Does the MEFI 1 controller use the baro compensation? I see it available in the stock calibration but the multiplier is 1.00 across the board.
Ironically I was just at Powell doing nearly the same thing. I was fiddling with the base cal and completely forgot about the baro compensation
Good thing I have every calibration I've made on file so switching back is easy.

Is this Dustin posting for Whipple??
I totally appreciate you replies man and don't hate, but I forgot to mention I am running an M1SC at 7psi.
My current AFR's (last time I checked) in Arizona are in the 13.6ish range cruising and come down as I get into boost to the 12ish range. Runs around 130deg. I have been running like that for almost 5 years now and feel pretty good with it. (plugs always look a tad fat tho)
To put it simply, I remeber running fat last time I was on Powell and did not spend much time under boost. I want to take fuel out and think I need the multiplier to be less than 1.00 but every other map I read has multipliers of 1.00 or above. Am I backwards in my thinking?

I will take my laptop and my wideband to Powell and sneak off when the wife is not looking and apply this information.
Thanks to all who had input.

EFI does not have a baro compensation in the map for the base map, only crank fuel. With MEFI1, your usually forced to do mods in the base table.
The good news is that the MEFI1 worked pretty good because it had hardly any resolution.
