Well i went digging thru online manuals for the titan and chevy and found this intresting bit of info, dunno if it will help anyone or not, but that is what this forum is about sharing info and not hiding it from others.. lets get to the bottom of this and start making pgm's again.. all thatshould be needed are a few POT's or potentiometers to vary the voltage from the gm tb to the nissan wireloom that way the ecu doesnt freak out. we used to work with these in a/c refrigeration but im sure someone out there is a electrician that knows more than i do..
