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

decipha wrote: ↑2022 May 17, 20:57 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

dleach1407 wrote: ↑2022 May 17, 18:42 That is not a slot maf, thats an old school "tonsil" style maf. You should be able to use a stock maf curve and just multiply the whole curve by .90, maybe .85 to get it close since its calibrated for 24s. Youre going to have to dial it in regardless.

If it's a newer style sensor it should be clearly labeled which sensor it is. If it's an early one its harder to identify. The outage listed above should help you identify which you have. Both of mine are 10 years old and still going strong. They are the first generation sensor.

decipha wrote: ↑2022 May 17, 15:06 Yeah 7 or 9 points is typical to test a maf sensor its only to show that the sensor works and reads air flow it is not a maf curve.

In order to get an actual maf curve you have to send in your intake manifold complete with the throttle body, inlet piping, air filter assembly and all - 100% identical to how it is in the vehicle.

PMAS makes about 25 different slot sensors that look identical so you'll need to manually dial it in as it could be any of them.

Its easy enough just let tunerpro correct it for you using the histograms
