Can't find older post, had a lot of info on electrical issues caused by ground issues etc on IQ chassis, put mine away last year with an int gauge problem, blank screen at low rpm. Sled is going to be apart soon to allow for new intake parts..., trying to locate common area for wiring shorting out/bad ground issues/regulator problems. Also, when I take in to get the top end update done, before they clear codes, does anybody have a code description etc to expect with a poss voltage regulator or ecu problem? Thanks!
