When MAT reaches above 62C the vehicle goes to .7 lambda instead of its normal operation of 1 lambda at idle. Anything above 1000rpm and the vehicle runs normal again. I've tried to change the MAT/TPS table to remove all the fuel it can with a setting of 68 but it doesn't remove enough fuel to fix the problem.
I have another VEMS in a different car that i'll be swapping out to check to see if its a hardware issue. This vehicle runs perfect in all other parameters except for when outside temps reach 105F or higher with a MAT temp of 62C or higher.
