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

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.

Ya, i will probably buy a tune from Trifecta since they have a tune for the Tranny too.

The guys from Fleece told me that the majority of the time they would use it in Manual mode, so when i want to go full throttle its always in manual.
No one has tuned an Aisin before. So uh, save your money there.

I have been working on another approach... Which is quite promising.

"TRIFECTA presents a complete powertrain power delivery profile recalibration for the MY2014+ Chevrolet Cruze 2.0TD Clean Turbo Diesel LUZ Engine and corresponding Aisin AF40 6-speed automatic transmission reprogramming.

Specifications of the TRIFECTA Performance MY2014+ Chevrolet Cruze 2.0TD Aisin AF40 6-Speed automatic transmission TCM calibration software reprogramming:

-Supplementary Aisin transmission TCM reprogramming compliments the ECM reprogramming and completes the TRIFECTA Powertrain Calibration: designed to work in unison with the ECM reprogramming for optimized performance
-Improved shift times in adverse shift patterns
-Improved shift logic
-Does not shorten transmission life or increase cooling requirements
-Retains all OE diagnostics functionality and TCM diagnostics
-Retains all OE error code reporting and functionality
-Improved fuel economy with improvements made to torque converter slip profiles"

And based on emails I have from Vince, it also gets rid of torque management.

No one has tuned it before. I don't know what more to say. Either its completely false, or is torn from another vehicle.

No other GM vehicle that was out when the CTD tune came out that had an Aisin to my knowledge.

https://en.wikipedia.org/wiki/AWTF-80_SC take your pick.

Look, they got a tune to work for the diesel, I really respect that. Something not very many people can pull off.

What I don't respect is how they sell their stuff. They live under the guise of borderline fraudulent statements like "increased combustion cycle efficiency" and make 100% false promises like that "it also gets rid of torque management". They will say the engine will throw gold out of the exhaust just to sell a few tunes.

That's all I'm going to say. I just don't want anyone to get hurt by them because they are promising to fix these transmission problems when they don't even understand how their own tune works.

What does the Wikipedia article mean...we all know what transmission it is...

Nothing in there says it cannot be tuned.
Im guessing he's saying they took a tune from another car with the same Tranny, like a Volvo or something.

You're just hating as hard as you possibly can. They've tuned the SRX for a long time.

There's one close by it's just the Cruze is on a long trip at the moment. :dry:
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...

You're lucky they prep your track. I have to deal with trying to launch my Cobalt (supercharged - so 14psi instantly off the line) on tracks that aren't prepped at all - that is unless I want to drive hours and get about one run in. Even with my 225 ZIIs it's impossible not to spin.

Ya, i was happy with the results and the people there were impressed too, both by the power and the Smoke, lol. My car doesnt have anything writen on it, quite the sleeper and when i did a run, there was so much smoke that when i finished and i cameback to the parking, there was still smoke in the air!

I was the only Cruze there and the only Diesel.

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.
