Does anyone have a MAF transfer curve that came with a Summit MAF calibrated for 30# injectors? I intend to shift to a LMAF when the funds become available, but for right now, I am stuck with the MAF that came with the car.

Honestly, I would try to contact Summit Racing tech department and see if they have that information. I would imagine it would be close to a pro-m 75mm bullit calibrated for 30#'s That curve can be found in EA.

the 'calibration' is relative to the intended application, find out what the maf was intended for then just multiply out the difference for the stock relative curve

I contacted the Summitt Tech department asking for the curve. This was there reply, "The units are listed for standard street applications with basic horsepower upgrades based on the injectors being used. These are not designed for high horsepower application where this information is required for tuning."

Not alot of help.

In that case, grab the MAF curve for a similar MAF that is calibrated for the same size injectors. The curve won't be exact, but it'll be close enough you can work with it. With a wideband, you should be able to work it out well enough.

That meter is a Pro-M 75mm unit re-branded by Summit....

If thats the case I wonder if he could call Pro-M with the serial number and get a flow chart?
