I'm hitting lean protection in 4th gear when entering boosting part throttle then punching it to full boost. It also happens when down shifting into 4th and going WOT. My datalogs show lean spikes as high as 32 AFR. My setup is JRSC (13 psi), full exhaust sytsem and CAI.
It's only happened in 4th gear that I've found and the car is undriveable right now, I will get smoked by anybody else. Could it have something to do with my WOT compensation tables for the lean spikes? Any advise is greatly appreciated. Had to zip the datalog file for file size.

What injectors are you using?

Rc 650cc

the lean cuts have been intermittent. tried to reproduce today and nothing, it was fine. pulled all the way to redline in 4th gear but the day before it was cutting out with lean spikes like crazy.

Have you discussed this issue with your tuner?

he hasn't called me back yet, kinda slow. grasping at straws but i read it could be a flaky connector to the MAP sensor.

It could also be that your lean protection is just set too aggressively.

at first I thought so, but this is ok right?

protection 1
14.2:1 maximum lambda
3 inches engine overload
250ms trigger time

protection 2
13.1:1 maximum lambda
3.9 psi engine overload
250ms trigger time

Try longer trigger times of 500 or 1000 ms

my tuner said to try raising the boost cut in the "protection" parameter from 12psi to 13psi. i tried that but i was still cutting out.
I'll try increasing the trigger times, thx u.

i think making the trigger time longer is going to work, so far so good, no lean cuts. something seems to be funky with my kpro. monitoring the display on kpro, even in neutral, i can see on occasion the A/F hits 32 for a brief moment. unexplainable to me.
