Ever get where the fuel gauge will go past the full mark and the water temp will rise up to hot? It used to do this once and a while but has been doing it more often lately. Any clue how to fix?

 

I don't know, but I'm having similar problems. My temp gauge just dies when I go into boost. Stays dead for awhile then pops back up to its normal temp. Is this a problem on FC's?

 

Usually caused by cold solder joints, read the FC FAQ sticky'ed at the top of the main page, or search on the username 'Icemark' and you'll find a lot of info.

 

I didn't have this problem before I went turbo. Could that be my problem?

 

cold solder joints in the cpu? I resoldered that before to try and fix horns. Or is it the ecu? Resoldered some spots while I was doing the BAC transistor fix, maybe I didn't get one so well. It doesn't do it all the time.
