Yeah, timing was altered. I've been running my missing tooth at 55 degrees since I built the MS. With the polarity corrected and the timing locked at a fixed value, I had to change my missing tooth angle to 60 degrees to get the commanded timing to match the timing light.


With this problem behind me and emissions in front of me I decided to turn table switching back on. I can set up an additional 16x16 volumetric efficiency table and switch to it based on various parameters. I set mine up to switch based on manifold pressure giving me a map for on boost and a map for off boost essentially making it a 32x32 table. The big emissions benefit is having good resolution in heavy vacuum where decel transients tend to be very rich. Having smaller cell resolution (now 5kpa x 300 rpm) across the whole map doesn't hurt either.
