Yesterday I pulled the MP Chrome ECU and installed the Rev-N-Nator that I bought about a year and a half ago. Back then when I tried it, the engine detonated worse than it did with the Mopar ECU. I had to retard the timing to 29 degrees to get it to stop knocking. That put my initial at 15 and it felt lazy off idle. Since then I have learned how to set the advance curve in this distributor.
I was going to try vacuum advance but the instructions read that their ECU isn't compatible with it. No problem.
Theres more tuning to do to get the A/F readings closer to the ideal. I expected that the thicker head gaskets and lowered compression to cost me some power. I figured the head porting would offset it. As it is now, the car flat out scrams!
It sounds great, it feels great. After all that I have been through in the last 8 months, I would have been satisfied with the same power but with NO detonation. Its a nice plus to have these changes result in MORE power too.
