Hello!
1. Can the Map Delta, Tps Delta and Engine speed ROC math be changed? Specifically the time constant?
2. I assume the above question is no. So i've started to try to write my own channel but I'm not smart enough to get the results i'm looking for. I've started with the equation of CNT(A) A being Tps Delta. It is not showing me negative values on - delta values. I'm trying to lengthen the time of the delta calculations and see if that gets me the data I'm looking for.
Outside of overrun fuel cut conditions every car I've tuned for 25 years on every standalone platform, during slow decelerations ie throttle reduction to keep distance from a slower car on highway, Lambda is always well below my targets. When steady state, or when accelerating through the same areas of the map, the lambda is where I want at .9. While I try to use 02FB to correct it, I think if I can write a math channel that modifies the time base of the 3 channels listed then I can use that math channel as an axis on 4D fuel and correct what I've wanted to for YEARS. I tested this morning on a customer car and wrong the above math channel and entered it as an axis for testing. Now I just need to perfect the math.
I also tune OEM ecu's and for years have been wondering how they combat this condition during closed loop fueling without the 02's even twitching since fueling is perfectly reaching targets. Multipliers in the background i'll never understand i suppose
Thank you for any guidance!
