no, the maf has nothing to do with the injectors.
You simply copy and paste the actual maf curve in your tune from the homepage
fox 24lb curve since ita cald for 24s
And then the 60lbs siemens patch since I'm running the black Siemens 60's?
I recall (a LONG time ago) you said that you use high/low to get close, and then the MAF to fine tune the rest?

I will thanks!
I see that some MAF curves have kg/min, lb/min, etc. Does it matter what one I put it into, as long as the unit matches? How does tunerpro know what one to use?

No, u have to put the injector data in first then the maf
read the comments on the injector high slope
they are all the same just displayed to you differently
i wouldnt recommend using the maf he poated as it doesnt go to max and min volts and the points are outside of the histogram so youd have to manually dial it in

I put the injector data in (using your Siemens 60 patch), then the 24lb calibrated MAF, SARCHG,
It wont run though, at least not well. There's raw fuel coming out of the exhaust and it ended up filling up the #1 cylinder with fuel to where I had to take the spark plug out and turn it over.

Yes. I might redownload the A9L2 and start back over to make sure.

I have 60's so I multiplied the right column by 0.31666666666666666666666666666667 (19 / 60)
I'm going to try the redone tune and see what happens.

Yeah pump shuts off after 3s of priming, how do I verify it's communicating well with the ECU?
I'm kind of wondering if I have a bad HEGO, or stuck injector or something on Bank 1, as that was where the #1 cylinder filled up with fuel.
Bank 1's HEGO volts are a LOT lower than bank 2.
