128-130deg computer issue?

I posted this in the new edge Cobra section but I spend alot of time in the Terminator section and it seems to have much more traffic.

So what does the computer do at 128-130deg that would kick it back into closed loop and stay there. It happens every time at that temp.

Any ideas, this has been a long term problem and we are grasping at straws for an answer?:shrug:

Its definently in the tune. Maybe take it to a well known tuner and have it looked at. It seems odd that its doing it at that particular temp. Its not even really warmed up until the 160 mark.

Been tuned a couple times by a professional and he is stumped also.

so the pcm is actually seeing 130* and flipping to closed loop? sounds like a processor issue. tried a different one? if you have, there has to be another input, what tho????

It is actually 128deg that it flips. The tuner seems to now think that it could have something to do with the binary code since 128 is half of 256 for some reason. He is going into the code to see if he can find a glitch.
