First Dyno Tune... Thoughts, Results, Etc.
Hello all, new to the forum but have been reading here for months.
I decided to rent some dyno time and try tuning my 100% stock 2010 Corvette before getting into the big stuff on a modded car. My goal was to just get some seat time with the software... I have several thoughts, numerous questions and feel a bit overwhelmed. I was able to gain roughly 15HP and 14Ft/LBS which seems good to me for a "tune-only" car.
First tune was to eliminate CAGS - No problem
Second tune was for FAN settings with the 160* Stat - Seems fine. I lowered temps 15* and brought in some PWM% a little earlier and maxed it out the 89.9% a little earlier as well. Is this typical/correct?
Third Tune was for commanded A/F for both Normal and PE modes - 14.5 and 12.5 respectively - this netted the biggest gain of the day. Durring this I did disable the MAF, STFT, LTFT, Etc as listed in the tutorial to try to log the for some VE tuning, but the car seemed to be so close it made adjustments almost not worth it - is that normal when tuning a stock car? I also noted that even though everything was disabled, I showed some LTFTs while logging... I thought that was odd, especially since the car was in open loop? This is where i got overwhelmed and just left the mods limited to the A/F changes, turned the MAF and STFTs back on and started to mess with spark.
Fourth Tune was for Timing. Car took about 4* from about 0.50 @ 2500 up. This combined with the A/F changes netted the gains I mentioned above.
I guess I am looking for some input on my approach/results. I have been waiting to post until I had some actual time tuning to avoid questions that could have been easily answered by just using the software, but now that I have used it, I am just as confused as before... lol.
Just on a side not, if it matters. I did have a LM2 connected while logging as I installed a bung pre-cat as I had seen on sites like LS1Tech, etc. (in the top of the cat)
Thanks,
Mike
