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.

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.

Thats why a 1/4 mile is better, because even if you dont have the greatest start, the power of your car can still compensate for it.

I was making sure I wasn't doing something that would be invalidated by a minor detail.

It'll be June/July when ill report back

Would prefer if you made the deal beforehand then figure out who specifically I need to send it to in an email.
Thats what i got from Fleece :

This is not something we would do just because it is not our product we could not stand behind it. We only sell OZ Tunes. If the tuner is incapable of loading it on the autocal I would be cautious of trying it.


​I think thats a NO.

Incapable? Autocals are linked to basically the 'master' tool. You save your file "For Autocal" and then any Autocal linked to yours can flash it (no one else's Autocal will be able to flash it). I have done it far too many times now.

So long story short you'll have to buy one from me then. Or convince them to send you the unlock code. If you wanted to.

Thx for the offer, but i will keep the tunes i have right now.

This is my daily driver and its enough power. 15.4 quarter mile time is good enough for me.

If you claim your tunes are better than other tuners that sell them and you want to prove it in a challenge that you have issued... Shouldn't you send a loaded AutoCal to @Poje to install your tunes in his car and run them back to back on the same day. Then if your tunes are superior you have great marketing to sell more of them, and if they are not, then he can send you back the AutoCal and run his current tunes. I would imagine that Poje may even buy them from you for a prearranged discounted price if they perform as well as you claim...

Whenever I am doing an installation article the manufacturer or tuner sends the tuner/module/programmer to me to install on the given vehicle. In fact one arrived this morning for a future article...

My focuses aren't on tuning cars for moneys. Got far more lucrative endeavors for that.

Plus there's the whole legal issue of deletes which everyone seems to simply forget about it. Shell companies can only take you so far.

I'm assuming Fleece locks the tune so that only they can upload a new one? Is that the issue I'm seeing here?

Did you tune the car from someone in Quebec, if yes, i could meet him/her and we could do some tests.

I havent read the entire thread yet bit couldnt resist responding.

I have been using trifecta tune for couple of years. Brand new the trans sucked. Rough shifts, hunting for gear... couldnt decide. I hated the going to neutral as you come to a stop also hated the automatic downshift when I was trying to coast for fuel savings. I absolutely loved the tri tune and it made the transmission shift beautifully and as I was accustomed to in all the cars I've owned in 50 years. As fuel economy continued to get worse I set the engine tune back to factory but left the transmission tume. Now I've discovered that my decrease fuel economy was at least partly the map sensor and EGR things with all the soot build up. Just cleaning the map sensor today restored 8 of my lost 10 MPG and I'm considering going back to the engine tune to see how it does. It is certainly a lot more fun to drive that way it really wakes it up.

Funny that you say you lost fuel mileage with the trifecta tune. I was under the impression that trifecta's tune (along with almost any other tune I've had or heard of) they are only made for WOT. Most of the time people who experience a loss in fuel mileage, it's because they can't keep their foot out of it because of that new found power. ?
