1226870 Eprom Question HELP!

[Mikepoore at aol.com]

I tried programming a 2732 eprom for my 1226870 ecm. I used gmedit to do it. 
Everything checked out ok on the programmer. All I changed was the cooling 
fan temps and idle speed. I plugged it in and the car will start and run 
fine. The problem is that the SES light flickers very quickly. If I plug my 
scanner into the ALDL the flicker goes away even after unplugging it, but 
once I shut down the engine and restart it the flicker returns. 

Am I using the wrong speed eprom? 
Does it matter if it's a 2732, 2732a, 2732b, or 27c32?

Any suggestions or comments appreciated. I don't want to test drive the car 
until I am sure I it isn't going to melt.
