Big D Posted February 15, 2008 Share Posted February 15, 2008 If you have or know someone who has an eprom programmer, you can find the proper data on the internet. The 1227747 ECM is one of the most hacked units and there is a lot of info available on it. It is easy to reprogram for modded engines. I have been using one for years on a 383 stroker and just modified it for flash programming / data logging with an EBL add-on board.
