How does this calculated AFR table look?
I auto generated this AFR table for MicroSquirt to auto-tune to. Is it reasonable? Should it be adjusted anywhere? Currently K26 stock headers and intercooler, soon Rarlyl8 headers, K27 hybrid, TK intercooler.

I'd fatten idle bins. Aircooled engines like it richer, like mid-13's at least. Everything else is pretty close to my target too.

He probly wont be using auto-tune for idle anyways, but yeah batch fire doesnt like an idle that lean.

On pump gas I would say kinda fat Carole the board. I agree in the idle. I'm at 13.2 on pump and corn juice

That's supposed to say "across the board" Siri

My map is a bit leaner - I do not go below 12.2 anywhere.
My idle is richer. I try to keep my richest areas of the map overlapping the area of the rpm range where most torque is made (relative to other cells for each horizontal pressure level).
