Following this thread : http://www.cruzetalk.com/forum/201-...cussion/196210-small-changes-reduce-heat.html

And after chatting with Corbin Murphy @ Fleece, i wanted to know how much power my car was making and if the 50hp tune was indeed stronger then the Race tune. (The tune you get when you delete)

So Corbin made a Tune that "should be the 50hp tune scripted over what you had." (The 50hp tune is one of the 3 tunes you get when you just tune a stock Diesel)

So here are the results : Land vehicle Vehicle Car Chevrolet cruze Motor vehicle
Line Text Pattern Design Architecture
Electronics Technology Font Electronic device Auto part
Technology Electronics Scoreboard Display device Electronic device

1st of all, if you look in the picture where you see my car, on the blue shield its writen Mustang Dyno, so these are good numbers. The guy there never did a Cruze, didnt know Diesel existed and was quite impressed.

I was right! The 50hp tune is indeed more powerfull then the Race tune, but the amount of BLACK SMOKE you get is ridiculus, lol. The guys at Fleece did an incredible job on the Race tune to make it this powerfull with almost no smoke. On the Graph you can see the difference between the two tunes.

181hp and 296lbs of torque at the wheels for the 50hp dirty tune. The torque punch earlier too, its quite violent and funny when you drive.

173hp and 286lbs of torque at the wheels for the Race tune. Smoother driveability and no smoke.

Conclusion : I will use the 50hp tune only when i go Drag racing or to do stupid things. Its not worth it on the street for the difference with the Race tune.

I've kinda put my tunes into generations. I know some of the Gen 2 and 3 files are easily sub 15 second. But they have problems which the what I call the 'Gen 4' set out to solve.

I haven't really had the time yet to make a super powerful Gen 4 version yet. The one I do am working with is relatively smokeless and is fairly mild. Definitely not as wild as the earlier ones but some people like it a lot better.

Hey if you want to try it let me know. Although there's the whole.. Autocal issue.
From what the guys at Fleece told me, unless you change the Turbo, you cant have more power w/o big risk of boom.

They said that the Turbo was the most feeble part of our setup and when you do around 200-210hp at the crank, you are at maximum safe lvls and im right there.

So sub 15s with stock everything like i have? No way.

Anyway, its the best a Cruze Diesel can do, unless it would be way more modified. (Bigger turbo, injectors, suspension, ect...)

But with more power, traction would be a big problem. Even at my power lvl i had difficulty hookin'up on a preped track with our open diff, that's with 225mm PZero tires, lol, so...
I was doing 2.2s on Nankang 245/35/20...

I bet a set of radials and a loose extension rear shock will get it down to 1.7s

Something's up with Fleece's tune. It really shouldn't smoke as much as it does. Not really sure what to say, it's not like I can look at it and say what they did wrong. I can only speculate...

lol, nothing is wrong!

This is not the normal Fleece tune, its a tune i asked for, an hybrid tune between the Delete race tune and the 50hp tune, i explain that in my 1st post.

Alright alright.

So open offer. If you convince Fleece. I will send them my latest and greatest 'mild' tune to them for no cost. They can package it for your autocal and there ya go. I trust them enough not to blatantly steal everything in it.


And then. There can be honest comparison.

Ok, add your car to your garage and make a signature detailing all the mods you did to you Cruze, then have pictures proving it. Then go on quarter with equal or less mods then i have and do a better time.

Hey Poje, I just noticed your in Canada, where? I'm in Ontario where they test for emissions. does the tunes pass the test? Or do you need to do something every time you take it in?
They do not test in Quebec and no, if you dont have the After treatment, you wont pass the test.

Sort of? It's more complicated than that.
Ok, i will accept to test your best Tune, but i will ask Fleece to check it out, to be sure it wont destroy my turbo/engine.

Would prefer if you made the deal beforehand then figure out who specifically I need to send it to in an email.
Ok, i sent an Email to Corbin at Fleece, i will tell you what he says.

Just so we understand each other:

Intake
Tune
Exhaust
DOT tires

Correct? So if I was to tune my own car, I am not going to hear "But I meant *insert shop name* tunes only". Correct?

This thread is exciting. I want to get to the track, we have 1/8 locally. My car launches great with a little bit of stall, bottom end is awesome, but just falls flat on top of the rpm range. I feel like it would be low 10s in 1/8.

I would personally like to see high 9s and I would be happy. Guess I need to go and get a baseline first.

I bought this car for strictly commuting fuel mileage, but 1 emission hiccup and delete/tune later and I wanna go fast.
