I took the car for a qwick spin tonite and it all the sudden lost power and the scanmaster went blank. Pulled over and the ses light is falshing fast and Im running on 5 with black smoke. I go get the trailer and bring it home and get a code 51 from the ecm which said ecm or eprom. Anybody have an idea of what I need to check. The ecm has had the powerlogger in for 2 years and its Turbo tweak chip. Thanks for any help.
