water temp and fuel gauge problem
 

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.
