Help with Accel TPSDot curve
 

Hi All,

Here is a picture of my accel tpsdot curve. I was told I need to redo my curve so all values at negative TPSdot are zero. I was also told I have the accel enrichment adding fuel when I lift is a very undesirable behavior. Can someone explain to me why? This below setup is making my car running very smooth.

It is undesirable because your engine does not desire to have fuel when you lift off the throttle.

I actually use TPS dot values lower than 0% to trim fuel out when I lift. You need a zero column and could benefit from more resolution in the 0-150% TPSdot throttle tip in range. It should help with drivability. My curve is not perfect, but when logging I never get any lean spikes in all ranges of throttle speed. I tuned it the way I did to compensate for sucking at EAE/wall wetting tuning.
