Hi, I'm hew here but love the site. Everyone has been extremely helpful. Here's my question....The EEC fried in my 93 Lightning 5.8 351w e4od, should I replace it with the same exzact one? Should I go with aftermarket? I have a vortech geared supercharger w/ the whole set up on it, can the stock eec be programmed for mods?
You can try looking on nloc.net, in the classifieds for a used ECU. You'll at least want to try and get a factory type ECU like C3P1, C3P2, C3P3 or ICY1 because the transmission settings are a little more aggressive, and the timing tables are different between a GEN 1 and F-150. Otherwise, any 5.8/E4OD (pre OBD-2) ECU from that era would work
