I'd even be happy to see the factory calibration (even if I had to buy LSEdit to read it!)... but I'm sure someone has been down the path of calibrating Air/Fuel and spark for a ZZ502 before, and I'd sure like to benefit from their experience.

My heads are a little different (AFR340), but I'm getting some surprising results, like 25% VE down around idle, and could really benefit from what someone else did.

Thanks!
Dave
