ZZP and BNR is all I mainly hear from other local Cruze owners. I’m shocked.

 

I should have known as a Christian not to go with Bad News Racing. Definitely a freudian slip when they named it as they're nothing but bad news...

 

I'm a Christian and have been with BNR since they started tuning their own cars. Does that make me a lesser "Christian" than you? Weird post to make, during the holiday season at that.

Why did it take you 18 months to report this experience, during the busiest holiday season for both companies, right after BNR releases the GTS250 to compete with the V3? As a Christian, don't you also believe that there are no coincidences?

If you look at the actual tuner notes (item 3), the dyno operator clearly states that there are erratic/unexpected knock readings. Further down the line, it is re-affirmed that there are large amounts of knock being reported. You requested that the sensor be "dulled," which essentially means forcing the ECU to ignore a reported fault. To my knowledge, that's not how BNR operates because it places the engine at risk. The correct fix is to address why the high knock is being reported (could it be your sudden burning of oil?). This is like sticking electrical tape over a check engine light.

Dyno operator recommends replacing the knock sensor. Was the knock sensor replaced? There's no indication from the initial post that it was.

Moving on, we're supposed to believe that the car started burning oil a month after all of this happened, and that the car was in perfect mechanical and electrical condition prior to that? In my experience, that's not how any of this works. What was the fix for the oil burning issue?

Finally, you said that BNR said the chinese castings were junk. Can you provide proof of this?

I'm sure Tim is a fine tuner, since I've heard of him before, but this post is just...weird.

 

FWIW I used to have a Grand Prix. I came across ZZP about 15 years ago and have been using their stuff for about 15 years. I have never been let down by them, they are even good about answering my questions when I have emailed them.

I have often thought GM should get with them, to make ZZP versions of some of their vehicles.

 

So, you edited the tune, on your own and are upset they cannot edit anymore for you? Do you realize the liability that would create?

No wonder you only made that little bit of power, there is something wrong with your engine/vehicle. Knock sensor is there to save your motor... would you rather it blow up?

Since you brought religion into this, for some odd reason, I think you need to have a come to Jesus moment and get back to reality.

 

Like others have said, it's quite suspicious that you left a review on ZZP's website for their tune back in March, but all of the sudden now you're here posting this as we're going into the busiest time of year for both companies...

But to address this bit by bit-

1. Yes I told you you had a boost leak OR a leaking injector. Your fuel trims were off the charts negative, meaning you're either losing air somewhere or getting too much fuel versus what is being commanded. So there are only two possibilities, this isn't magic. You either have an air leak, or a fuel leak, or potentially a bad MAF sensor but that is far less likely than the other two options. You told me you installed brand new Bosch 42LB injectors from a reputable shop. If the injectors are not the issue, what option remains? A boost/vac leak. Over the course of our years of tuning, you did in fact find multiple boost leaks, and faulty fuel injectors. See screenshot.

2. You were told by BNR AND the dyno operator you went to that you had extreme knock spikes and I asked you if you had something rattling around, like a heat shield or exhaust part, that would be triggering false knock from the sensor. Knock is detonation, and if the engine computer detects knock (false or otherwise), it will reduce power in any way it can to save the engine. The dyno operator commented that the BNR tune you took to his dyno was conservative on fuel and boost (you can read this in the report you posted) and therefore this knock must be false. He recommended you get a new knock sensor.

3. I did say dynos can be off by a ton, depending on the operator, but you're making it seem like I said your specific dyno was 110HP low or something. Here's what I said:

4. I didn't say chinese castings were junk. You asked me if certain parts would fit the chinese castings on the zzp turbo. I told you they most likely wouldn't.

5. You also still had DTCs for crankshaft position sensors all kinds of strange random activity, where I again told you that you had either a boost leak or some other issue based on the logged data.

6. After all of this, and with what I would assume is still a motor that is running like crap due to mechanical issues that have likely either never been resolved, or were resolved after this conversation, you told me you bought HPTuners and were editing things in the tune, and wanted me to continue making edits to whatever you made.

I don't think its crazy for me to not want to touch a file that you've been all through and made changes to who knows where and what. I am not going to put the BNR name on a file some random guy is editing and changing so he can go max out the boost tables, blow the motor, and make a post that BNR blew his engine.

I'm happy for you that you got the car running in whatever fashion you accept as good. Best of luck to you.

Next time you go to bash someone's reputation, don't leave out things or make things up, it's not very Christian of you.

I just did a quick datalog, (E78_0008) WOT second gear (two runs) till it hit rev limiter.
Knock retard = 4.0
Retard Due to knock = 3.5
Much lower than the 11.8 in the first log I sent, but only a quick run.
Also, another quick run (E78_0007) just after I sent the first log was 5.1 and 4.0
Will look into the spark plugs and gap.

A friend is going to show me how to gap the spark plugs as I haven't done this before. Do you have a recommended gap to set them at? What numbers should I see on the data log so I can check the results? So from what I can tell, it will be fine to tune the car but I will likely lose top end power until I gap the spark plugs. Is this correct? Thanks, Murray.

Hi Jerry,
I have just ordered a ZZP catless downpipe too. Not sure how to proceed. Should I wait until I have it installed to send you a data log or can you adjust the tune for it beforehand? The downpipe will be on an otherwise stock exhaust so I'm expecting the CEL to go on. I also have the AEM intake which you have already tuned for. So far just the base tune and one custom tune.
Thanks for your time,

Hi Jerry,
I've decided to port the intake manifold too. So I'll send in a data log after I have the downpipe and ported manifold installed. Not sure what you want to do in the meantime. If you could just adjust the tune to not throw the CEL would be great, but I'll just leave it up to you to figure out what you can fit in. I can just turn off the CEL with my EFILive device in the meantime if necessary.
Sorry for the confusion,

Hi Jerry,
I have the ported intake manifold and the ZZP downpipe installed now. I have attached a few logs for review. The BNR WGA has been shipped too. I have the Rislone Injector Cleaner in the fuel at the moment, which might explain the misfires in one of the logs as it's never happened before. Also new plugs as the original iridiums have done over 100,000. NGK BKR7E V-Groove (copper core), which I'm assuming is the Aussie version. I gapped them to 22 thou. I have been trying to reduce the KR so any help there would be good.

It hit overboost up the first hill in 4th. Also it stalled while idling at the end of the 2nd log, but probably just the computer adjusting. The boost jumps around quite a bit around 20-22psi too. Still waiting for the WGA to arrive, so maybe that will fix it?

It looks like the KR is only before the engine reaches temperature. Looking back at logs it goes away mostly and has been generally up to about 2°. I might try adding some octane booster but it might not be high enough to worry about. I've never actually heard any pinging. Also the old tune had been running real good as a reference...

Hi Jerry,
I went back to the old tune and it's the same, but it's not hitting overboost. It looks like the OE WGA is failing, the max boost has dropped and it's a wobbly line on the chart. I guess just a coincidence and luck that I have a new one arriving hopefully before the end of the week. Power has dropped also.

Hi Jerry,
The new WGA is installed and with the new tune it runs fine with no overboost. I started at 1 full turn and now on 2 full turns. Boost holds much, much better in high RPMs but it's making less power. I added octane boost and it's back to the same power before the downpipe, intake porting, WGA and updated tune. Not sure why I'm not making more power? Can you update the tune for more power?
The last log attached is after adding the octane booster.

Hi Jerry,
I'm really not happy with this tune. I had the most torque and least KR with the original custom tune after I installed the ZZP downpipe and ported the manifold. Things started going wrong when the original tune was changed. KR went way up, so did INJDC1 and torque went down. Then with the re-tunes for the larger injectors there were no improvements. I was expecting big improvements and gains with the downpipe, ported manifold, BNR WGA, 42# injectors and all the re-tunes for these parts.
Please review and explain what's going on with these tunes because I can't go back to the original tune with the new injectors.

It looks like you have a boost leak, can you check for leaks and let me know.
M
Murray Snow
, said 4 years ago
Hi Jerry,
Lots has happened! I boost leak tested, all three PCV valves/diaphragms were gone. It slipped by me because the intake nipple was still there and there was no hissing/suction on the cover. All the vacuum was going through the turbo inlet. I replaced the cover and both PCV valves. It's not perfect but it takes about 30 seconds to drop from 20-10psi. One of the new 42# injectors is causing the misfire, still gotta sort that out, but doesn't look like a huge problem. Replaced the gasket with the cover and also a new intake gasket. Spark plugs seem OK for now. KR seems largely fixed except for when the engine is cold, but that's probably normal I suppose. Torque is still lower than expected and boost in top end is low, but here is a long log so I'm assuming that's just because it's the first tune as you asked to be logged. This is all on the full new tune you made me. Thank you for finding the boost leak, it revealed many problems with the leak test.
Kind regards,
Murray...

Hi Jerry,
The tune is good! The new pre-cat O2 sensor made no difference. After looking at logs more, the O2 sensor drops to 0 volts when off throttle, so under vacuum, like you said. The boost leak test took 2 minutes to drop from 20-10psi. There was an intermittent leak through the oil filler cap so I replaced the o-ring but made no difference. I have no clue where the air could be coming in as it seems 100% air tight under pressure. Any ideas or advice?

Could be valve cover gasket, could even be an exhaust leak or something.

Murray Snow

Hi Jerry, I've done some work. New: MSD ignition coils, BKR8EIX's, purge valve, aftermarket BPV (GFB) and post-cat O2 sensor. No boost leaks. The boost holds much better with the BPV so it needs a bit of tweaking as it seems to dip then goes up again. While the post-cat O2 sensor was unplugged the STFT stopped spiking to 99% but obviously threw a few codes. With a new sensor the STFT started spiking to 99% again, have no idea what's going on there. Also seemed to lose a bit of low end torque while unplugged. Also it was throwing a P0172 rich code before all this but not after the recent work. The logs show that it starts going rich after it starts purging, but the new purge valve made no difference it seems. I changed some PID's for logging and it shows that the CanVent Open Circuit Test (CANVOP) fails. Not sure exactly what this should be but it fails 100% of the time, which makes me think it's not connected but I haven't had a chance to get under the car to check it. Possibly when it purges it's sucking in from the tank without the vent closed?
A lot to review so I thank you for your patience. On a good note, the KR is considerably lower now which I'm attributing to the new coil and plugs, but not sure.
Kind regards,
Murray...

Just to confirm, you are running 42LB injectors green bosch injectors? Where did you get them? If it's not a boost or vacuum leak, it could be a leaky injector, or it could be the air intake you're running, or even a dirty MAF sensor. That's what the trims tell you, the car is running rich or lean compared to what you're commanding, and in this case it's very rich. Do you have an atmospheric bypass valve?
M
Murray Snow
, said 3 years ago
Hi Jerry,
Yep, I'm running the bosch green 42's. I got them from a performance shop here in Australia, they are definitely genuine. There is a misfire following around one of the injectors though. I swapped back to the stock injectors with the first tune and it still runs rich. I've attached the log with the stock injectors for you to check out. I've got the GFB bypass valve, but didn't seem to make any difference from stock other than holding more boost top end. I've still got more diagnostics to run regarding any boost leaks, but from what you're saying it must be a pretty big leak, which should have shown up pretty easily. I also changed the AEM intake back to the stock air box and didn't fix it...

Hi Jerry,
I've installed the ZZP intercooler. I'm hoping it has fixed any boost leaks. Here is a log with it installed, it'll probably need some tweaking. It's not making full boost, otherwise seems good...
Thanks,
Murray...

Still leaking. Do you have the PCV fix kit installed? If not, I'd recommend looking into that

I've gotta take off the intake manifold to check my pcv mod, I think the cheap epoxy may have melted. My 2011 Cruze won't do flex fuel, but will it do a straight E85 tune? Would my setup be capable of that? Or maybe with your FPCM upgrade?
Thanks,
Murray...

Yeah it would do straight E85 all day with the 42s, no FPCM needed but wouldn't hurt.

Hi Jerry,
There was a leak in the boost gauge, this should have fixed it.

It's still really rich, maybe a leaking injector or something? Or still a boost leak? This tune isn't optimized for E85 but will let you at least run it. Fix the injector or boost leak and log this

Is it the short and long term trims telling you it's rich? I had been trying to fix that for ages and I went back to stock injectors and their tune and the trims were still way off. Would you mind checking the first log I ever sent you to see if it's running rich please? The trims were off since I bought the car it seems...

They've always been slightly rich, but not as bad as they are now. Have you ever done the PCV fix? The PCV system on these is terrible and always goes bad.

OK thanks. I've done the PCV fix, I took the intake manifold off a few weeks ago to check the cheap epoxy I used on the PCV fix. It seemed OK but I redid it anyway with JB Weld but it wasn't the issue. I might test it with the PCV system completely blocked/disconnected. Still waiting for the new MAP sensor to arrive...

Hi Jerry,
The car has been to a performance shop for diagnostics on a dyno. I have attached a few pics of the results. These results are using the E85 tune before the FPCM update. I have put a new knock sensor in but it didn't make any difference.

Ok, so do you want me to turn down the knock sensor's sensitivity? I can do that but I don't do it usually because then people have problems down the road and love to blame me turning down the knock sensor at their own request.

Is the KR the reason why you can't add more timing and power? Dyno results are only 140HP but it should be much higher than that. It would be good to reduce the knock sensor sensitivity as we know it's definitely false knock with the current setup. I'll have to take off the valve cover to check valve lash and anything loose that could be causing false knock. I'm really keen on getting this E85 tune further optimised...
B
Bad News Racing

Did you dyno the vehicle completely stock on THAT specific dyno? If not, you can't really say 140HP is low. There is no standard for dyno testing results, the same car could make 100HP on one dyno and then go to a dyno of the exact same type down the road and make 180HP. It all depends on the gear used, the load used, the input conditions for the test, etc. I had a customer with a 2nd generation cruze with a big turbo go make 160HP on a dyno by him, get all mad, go to another dyno with ZERO changes to the car or tune and make 270HP. Dynos are great tools for tuning cars and seeing where the engine is losing power and needs adjustment but without a completely stock tune stock parts pull, it's impossible to know what you gained.
Here's the E85 tune with the knock sensors dulled

Thanks Jerry,
Yeah fair enough. The only comparison was with the AEM intake, everything else stock. In EFI live data log it showed 224nm, since then it's been as high as 318nm but usually around 290nm. Not sure how accurate any of that is though. The dyno guy said there's almost no timing in the tune so I figured that's because of the false knock and why it seems down on power...

Hi Jerry,
I'm rebuilding the engine because it started burning a lot of oil. At first I thought the piston ring lands had busted due to the extra power but the pistons are good. Actually everything looks good, perhaps the valve stem seals have worn but it started burning oil all of a sudden. The stock turbo looks in pretty bad shape so maybe a seal has busted, so I'm replacing it with a fairly standard Maxpeedingrods street turbo, just because of my budget. I'm rebuilding the engine, all big and little end bearings look new so it looks like it's been rebuilt before I bought it, possibly because of busted pistons. The cylinders look spot on 72.5mm with all hone marks still, so I think it's probably been resleeved due to busted piston damage (2011 model). I'm hoping to resolve any false knock with the rebuild and all replacement parts. When rebuilt, I'm going to go back to the tune before you reduced the knock sensor sensitivity and added timing. Just letting you know if you have any input or advice on how to proceed. So after dissassembly everything looks good, main bearings are a bit worn but not too bad (going to replace). Cam bearings a little worn but all good. It's not any tuning problem so I'm not concerned about that.
Kind regards,
Murray...

Hi Jerry,
I'm installing the ZZP BWv3 turbo with the rebuild. Do I need an update before logging data for you? If so can you make the adjustments for me please? Also please return knock sensor sensitivity to normal.

Hi Jerry,
The engine started well but I've got error codes P0016 and P0017, something with the cams or crank or sensors but not sure where to start. Thought it might just need a tune update for the new turbo though. Here's the log. I upgraded the valve springs and the BWv3 turbo. Also a very mild port/polish of the head, otherwise a stock internal rebuild.
Thanks, Murray...

Hello,
The crank sensor is faulty as the resistance on all wires is 'no connection'. That's why the cam codes were thrown. I ordered a new one today. It's runs fine and I'm sure I built the timing gear all good so hopefully that sensor will get rid of the codes. Got a couple of good data logs using the tune before you changed the KR sensitivity and timing. The BWv3 has the included WGA on it but I have a BNR WGA also, should I put it on? Also I have a GFB BPV which I can make fit, should I put that on? Other than that, it obviously doesn't run right so I'll leave that to you, lol...
Kind regards,
Murray...

I'm not sure if you can run the BNR WGA on the V3. It's not an OEM casting, its based on chinese knock off castings, so most stuff doesn't fit. Take a fresh log now that everything is installed and fixed for me

Hi Jerry, I haven't got rid of the P0016 and P0017 yet but everything else is finished and running really well considering it's the old tune. I installed the BNR WGA and it seems better than the included one, ZZP just said they make it harder to tune. There is a wierd boost cut off type thing which is like overboost but it doesn't cut the boost to 5psi, it hits at around 23psi. The timing seems good with zero misfires so I just need to remove the valve cover and cam solenoids to check the phaser adjustment but it would be good to get the tune updated in the meantime. Also if you can see why those codes are there would be awesome too.
Here's the new log.
Kind regards,
Murray...

Fuel trims are real negative, usually indicates a boost leak or vacuum leak. Would explain why boost is low/fluctuating too

Hi Jerry,
I've bought HPtuners and have made a bunch of changes to the tune file which I'm free to edit and change BTW. So I've been able to control the boost and have good drivability, but there is still a lot of power to unlock because something is really limiting torque. Here is the tune and log attached. I've also installed an AEM wideband with OBD2 for logging. Reducing the max pressure ratio seemed to remove that massive fuel or boost cut out. Are you able make any changes or point me in the right direction for which table will be limiting power.
Thanks, Murray...

Hey Jerry, no worries mate I'm learning to tune anyway...

 

As everyone is jumping on the knock bandwagon, I rebuilt the entire engine and Jerry still gave no updates. So blame the knock, sure...

 

So yeah, no updates so I tune it myself, and the result, no updates...

 

 

Just in case you still think I'm suspicious here is the picture where I missed the page join!

 

As for the dyno run, it wasn't for power, it was diagnostic to find this boost leak, but none. I never said anything about the 143HP other than it should be higher...

 

All the logs, messages and pics are in the links in the post I copied the entire transcript to. Go through it and make up your own mind...

 

All the logs, messages and pics are in the link in the post I copied the entire transcript to. Go through it and make up your own mind...

I made mine up. It’s your fault. @XtremeRevolution already caught your lie. Jerry didn’t say anything about how bad Chinese turbo casings are as you said in your first post. You even included the whole transcript where he doesn’t say that. You can’t be trusted.

 

So you had engine issues, it was knocking. You asked Jerry to make the knock sensor less sensitive. You blew it up and rebuilt, but can’t rebuild it correctly. Blame tuner. Do I have that right?

 

FFS, no you don't. The engine didn't blow up, the turbo oil seals were gone. The engine was in remarkably good condition with still hone marks in the cylinders. I already said it wasn't Jerry's fault so stop spreading bullshit mate FFS. I didn't rebuilt it correctly, I had to adjust the cam sensor rings to remove those two codes codes. If you must know, I scratched the surface of the head when I ported it and it eventually pushed a bit of the black rubber gasket material out and I was getting water in cylinder 4 so I have the head off now, it has been machined and it's almost ready to go with a new ZZP cam...

 

You said:
“I sent Jerry another log and he said they can't edit the tune now as I have edited it. And there lies the death of BNR and the misery of unlimited free retunes for new parts”

You’re blaming him because you edited the tune and want him to fix it. Then you ended the case with a smug comment saying you’re learning how to tune yourself. Then 8 months later come here and post this. Not sure what you think you’re doing, but ppl are gonna call you on your BS.

 

FFS mate, stop posting single out of context quotes. Did you not read the rest where he didn't give me any tune for my new build?

I'm sick of replying to these bullshit accusations when all you're doing is blindly defending BNR...

 

And the part where you said he claimed Chinese casings were junk? You’re making a complete and utter fool of yourself and straight up telling lies. I’d be defending any other company too in this scenario. You’re way off base.

 

See,

There you go, I finished my build, gave logs and expected an update. So he never said anything about chinese castings? FFS mate WTF is your problem...

 

See,
View attachment 305116

So he never said anything about chinese castings? FFS mate WTF is your problem...

Correct, but you accused him of it in your first post here. Anyway. Done wasting my time with you. If you can’t see what is wrong here that is your issue.

 

You're so full of ****...

 

He doesn't even make sense...

 

I already gave him logs and I didn't say everything was fixed...

 

Is that all from the BNR cheer squad?

 

"I made mine up. It’s your fault. @XtremeRevolution already caught your lie. Jerry didn’t say anything about how bad Chinese turbo casings are as you said in your first post. You even included the whole transcript where he doesn’t say that. You can’t be trusted."

Such wise words...
