Anyone else using MegaSquirt on a LA motor?

Care to elaborate on the newer magnum distributor? Wiring changes, settings, etc?
Or an off the shelf trigger wheel setup like youre talking about? Or at least a good writeup to use a commercial wheel and sensor, building my own brackets?

Ive become convinced that the lean burn is the root of my troubles. Everything points to it as it is the originator of the rpm signal. All the noise shows up in tach signal and ignition breakup, and every wiring test we have thrown at it has passed with flying colors. The leads are sheilded, every grounding and sheilding scheme has shown the same results. Playing with the gap in the distributor has changed the issues, but not eliminated. So it HAS to be the distributor, right?
I was about to pull the trigger on the msd stuff, but honestly cant stomach the prices on a hunch.
