The pipe temp sensor, if temp reading(voltage) is not withing a certain spec, it will add fuel which will cause you to be super boggy. When I had mine go bad I was able to tune it via my bd fuel box for my turbo and getting it running to get out of the back country. When the next one went bad I gave up and soldiered a resistor for the sensor. I left the sensor in the pipe and have run it this way for two seasons. I have heard multiply theories on why it adds fuel for no temp reading but never got an authoritive answer. What I think it does is if the voltage is not within spec, either to low or to high it adds fuel. This is because if its to high, your running to hot, lean, it richens it. If its to low, sensor has failed, its trying to protect your engine by richening it up. Thats just a guess, but I never found it useful. Running a fuel controller and egts I don't see much need. If i didn't have egts and a fuel controller I would probably still not run it, but I am fairly concesious rider. Sorry just realized this is the pro forum, mine is a dragon but I would guess the same logic?
