Default ECM Change - DIY?
I replaced the ECM on my '03 Cavalier. Is there a DIY procedure to get it working without Tech 2 scanner?

Never mind, my experiment didn't work. I could not get rid of Check Engine light, so I hooked up a scanner ... bunch of automatic transmission related codes ... mine has manual.
