Torque based engine control strategy can be a bitch sometimes can't it? Or rather the LACK of a torque based strategy!
Makes me thankful for the MS3-Pro's tables for automatic IAC increase when fan or A/C is kicked on, along with a delay so there is no "flare". Cruder than the OEM torque-based strategies, but more effective than just reacting!
Hehe, yup, the "old school" stuff that adds IAC counts based on AC or gear/neutral works pretty good. Does MS have multiples available? Meaning (for instance) Park/Neutral to reverse is different than Park/neutral to drive because generally reverse has more pressure than drive. GM didn't fix that for a long time or maybe never since they added adaptives for all of that. A lot of things can be tuned to make transmission transients vs engine transients better. The newer trans stuff is incredibly intense and for me it seems more time consuming to tune than the engine because of the complexity. I have to charge a completely different price now for engine and trans tuning. It's a whole new world as far as tuning OEM stuff goes and I am glad I only do GM stuff. There are a lot of things to screw up in the newer 6+ speeds
Watch out for that program counter in non-volatile ram if you think you can put it back to stock and get that lunched tranny thru warranty.
I've glanced at some newer aftermarket controllers that cost in the 10's of thousands of dollars and they look pretty powerful. How much can you charge for a tune? How much time can you spend for the dollar to the end user? MKE here on this site has a pretty good controller it looks BUT he also can tune and make changes to the operating system at will, not many can do that. I guarantee when he is done he will agree that it was at least $100k worth of time at MINIMUM for the EFI alone not including hardware and he will continue to tinker/make it better for years to come.
Yes, of course, you can make it close enough to get by for most applications. Just like carbs and the majority of those work pretty good when tuned. A carburetor is a beautiful piece. If calibrated close to the airflow demands of the engine it will "give it what it wants" in just about any situation. Atmospheric is the hardest for the carb, temp isn't so much because the fuel temp helps with that, hot or cold.
Anyhoosit, sorry to ramble.
