talked to FITech today in depth and they are pretty confident that they know what my issue is. I have the good ol points ignition system with ballast resistor and they are confident that's the issue. Sounds like the 6-7 primary voltage from the coil causes the ecu to improperly work causing my symptoms above 4,500 rpm's.
So next step appears to be ignition... What are you guys using for ignition/distributor as it looks like that's going to be this weekends purchase. I am planning on using their timing control so a distributor that's comparable would be great.
I have a reman electronic style dizzy that I believe would work if locked out but wanted to make sure.
At least it's something to go by... Anyways thanks again guys.
