Abaco Maf...how Does This Thing Work?

I have to assume that you're running 42# injectors?

What tuner?


Where did the file come from?

I have not played with your specific pieces and parts however....

Generally when using 42# injectors and any MAF, you would load the transfer function for the meter separately from the transfer function for injectors. It really doesn't matter what the meter is calibrated for so long as the EEC/Tuner know what the transfer function is. From there, the EEC/Tuner would decide what needs to be done with each.

Different size injectors have different size characteristics.

My suggestion would be tell the tuner that you h ave 42s (since this sounds like a drop down selection) and also tell it that you have a meter that is calibrated for a Stock EEC and 42s (basically, tell it you have a meter cal'd for 42s) --or-- load the transfer function for your specific meter, to the tuner (if possible).

See if the thing doesn't go, "Oh! THATS what you mean".
