In one datalog, I see you have a knock sensor error code. You need to resolve that.

You also have a burnout limit set at 6000rpm which is always on and that is why you are seeing a fuel cut at 6000 RPM. You need to set that to use a different input that has a switch you can turn on and off.

sorry it has taken me so long to get back to this post. what switch do you recomend, and the knock sensor error code is due to it being disconected, i am also having problems with the car starting to go lean after it reaches opperating tempatures. i still have the stock narror band o2 sesnors hooked up, do you think this could cause a problem ?

You can use the cruise control switch on the clutch pedal and just wire it to one of the inputs.

I would highly recommend getting this tuned on the dyno by a professional if you are unable to tune this yourself.
