3/4 of the way through my 2-bar tune my cars dash lights up like a x-mas tree check engine, srv asr, sys with security light. also all digital gauges read Lo. i thought it was my moates G3 adapter, but i put the the stock chip back in and it still does it. it was intermitent for a day but now is constant. does this sound like the ecm? i know the car was smacked kinda hard in an crash by a PO, the ecm bracket is even broke, but all this just started with pulling the G3 in and out doing this tune. also i disconnect the -batt before removing the chip, was i wrong on that? does anyone have an ecm i could barrow to see if it is my ecm for sure? or 1 for sale? 1992 lt1 m6
