Marty, thats what I thought originally, it was cutting the rev limiter back
because of the heat, but NO, it's not, I can rev it to 6000 rpms and it does
fine, but when I hit the clutch, shift and then floor it I get nothing! This
only happens under hot conditions, if I race at night time or under cool
conditions I don't get the problem. So no its not the Rev limiter. Rev
limiter is above 6000 rpms, never hit it before :)
It most definitely could be a connection, its always very humid here,
usually 80-95% humidity.

I second this. You don't have a computer heat problem. Clean all your
connections. Especially if you live in a humid climate with high temp
fluctuations. I know this will sound stupid, but I have to ask: are you
hitting the rev limit? General question to list: Is the rev limiter
threshold
heat dependent? (would make a kind of wierd sense from an engineering point
of
view).
