Hi everyone, this is my first time posting on the forum.
I have a lean spiked at low throttle input on my 1999 supercharged mp62 6 psi. Ecu is Megasquirt 2 vers 3.3.1
The car was tuned and everything seems to be working fine but the lean spike(hesitation) is driving me crazy.
I have messed with Ae enrichment but is doesn't seem to be helping the lean spike. If I am driving at 4k rpm and releasing the throttle and reapplying it, their is a hesitation that last 1 second or less and then it goes smoothly.
I have included a log and a copy of the tune.
Thanks you for your response and sorry for my english!

Reason: error in tittle and error in text
Your Accel Enrichment thresholds are too high, so AE is not playing a role in the moments you are having trouble. Lower your TPSdot threshold % from 100 to 15 and retest, it should be much improved. The rest of the AE settings need some work as well, but this would be where to start.
