Fuel starvation, who else?

boosted180

when my engine was cutting out at the track, i thought it was related to limp mode, but looks like it *might* be fuel starvation. when it happened to me i was at about 1/3 tank and it was most noticable going up the hill (top of 2nd gear, shifting into 3rd) just before the last two turns before the front straight at sow. the thing that makes me think it's fuel starvation is that if i am hard on the gas, it would cut out (engine almost shutting off, but not quite). it happens at around 5-6k rpm. but if i very slowly rolled on the throttle, it would rev all the way up to redline. and when it happened, my oil temps were only about 240-250.

i thought that hitting limp mode in the previous session somehow caused the ecu to not let the engine rev up again in subsequent sesssions, even though oil temps have gone down.

so at this point, im thinking it was probably fuel starvation, but am still not certain that it was not some form of limp mode....

does anyone know if it is required to reset the ecu after limp mode gets activated? or do you just have to let temps go back down and the car will behave normally again? answering this will allow us to rule out fuel starvation or limp mode.

I ran into the same scenario last weekend. I thought the car was in limp mode but when I hit the long straights, the engine was reaching max RPM's. Oil temps were reaching 270-280. I also thought it might have been the VDC kicking in on exit through the tighter corners. I didn't consider fuel starvation. I will pay closer attention next time out. I should have any oil cooler by then.
