Anyone else using MegaSquirt on a LA motor?

Ive gotten mine running consistently finally. Fuel only batch fire ms2 with msd distributor and box. Once i have the fuel tables dielaled in and some faith in the car again, im going to get Megasquirt controlling the ignition again.

Is it difficult to dial in the AFR with batch fire? It's relatively easy with the sequential. I did, however, find it interesting that a slight adjustment of the timing at idle made a quick change to the AFR vs. adding/removing fuel. For initial setup, I made my timing table look like a standard mechanical advance distributor.
