Usually gm just builds it in as tq management, this is something different.
It doesn't have to be perfect, it just needs to be done in two weeks...
A wise man once said "google it"
I agree. A sensitive throttle creates drivability issues (read lawsuits and warranty) with this much torgue in traction limited situations and with the manual transmissions for the less informed drivers that will be driving these cars. We just have to find the right way to tune this situation to our preferences.
This is why I like the old throttle linkage and IACV... when you are WOT... you're WOT!

Nice results but what was the stock base dyno?
While reading another thread on the Gen 5 portion of this forum, I read where a GM truck owner felt the Gen 5 trucks had their throttle settings "dumbed down" in comparison to Corvettes and Camaros. This made me think that if I did a compare between the two tunes I might find areas of the two tunes where the C7 tune had more aggressive settings for throttle, etc. where the C7 settings could be altered to get more aggressive. As you might imagine there are a number of differences. After just a cursory review, I found an interesting difference between the two where the C7 settings were LESS than the truck in what appears to be an important area relating to throttle. That table can be found under Engine>Airflow>Electronic Throttle>Throttle Area Limits>Max % Area vs RPM. The C7settings are less? An area for throttle improvement?
Attached chart shows the C7 settings. The truck settings are all 100's. (mistakenly posted table twice.) Click on thumbnails and they will enlarge.

Great write-up Chris, it's what opened up my understanding of the Torque based throttle/Engine Control and my tuning/logging strategies. Makes understanding a lot easier. I even referenced it in Andy's thread Even after peeling back the injector tables and charting the timing/fuel pressure sceanrio's, I have a basic understanding on how the fuel is added, how much and when. While theory as of yet, I am hoping to put to use this winter. Obviously the more experience you have, the better you get at it. Transferring from book knowledge to the PCM is the most difficult but rewarding journies.
Thanks again for sharing with us.
