Mark,
I am with Bob........Air gap too big between pickup and Renesis timing wheel ??.... Need to know as my EC-2 is set up for Renesis wheel and
pickup........You will have probably found solution to a problem I may
encounter in the future........Eagerly waiting for solution to mystery !!

I haven't cheated and looked at the manual.....since your gonna tell us anyway...eventually...but problems I've had before in race cars...plug wires running parallel to each other, and too large of air gap in the pickup in the distributor. Close???

Ed,
You are getting closer when you stated that it must be erratic ignition. (I wish I had someone to give me hints). Yes, the ignition timing was too far advanced, but retarding the timing didn't correct the problem. The coils are LS1 units, 6 ea, so any individual coil isn't firing any more often than on a 2-rotor. So, what's causing the erratic ingition? That's the question.

Hey, No Fair! Mark. Most of us do not have a Renesis shop manual. But, lets see the old CS had three wires, the new one has two wires - I get it - there is a wire missing {:>).
So it sounds like the problem was indeed ignition - well, its almost always either fuel or spark causing a problem. So if fuel is more or less ruled out it defaults to ignition. It probably wouldn't be a rev limiter as they simply cut out above a certain rpm. So either your ignition timing somehow was off at higher rpm (too much advance?) or else your ignition was erratic in its firing (such as exceeding the capability of the coils to recharge between firings - unlikely in this case).
But, without a shop manual to give me more insight, I must say I'm out of ideas.

Now Rusty!!! That's too obvious. ;-)
OK, another hint... I got a hint of what might be causing my problem from the ignition section of the Renesis shop manual.

OK, I'll give you a hint... it was related to my decision to change over from the original CAS to the Renesis CAS. I got that bright idea from last year's rotary get together at Tracy's.
I've got it. YOU were the problem :-)
