Speed density tune for EVO X
I notice lots of 8 & 9s running SD on stock ECU. Is this possible on a X? I imagine converting a X would be no different than a 8 or 9. Anybody running SD?

Nope...you can run only MAF or only MAP seperately, or both together...all depends on how the car is tuned. With that said, yes, you still need both functioning properly and on the car... e.g. you can't just get rid of the MAF sensor if running MAP only.

I'm going with what Scott said here.
U can run either/or, but needs to have both to run efficiently. The X comes with a factory 3-bar map sensor. Aftermarket SD r 5-bar map sensors. U can run MAF on low rpm and switch to MAP on higher rpm. The crossover is smooth as long as the tune is smooth.

I am not tuner and can be completely wrong, but i think you can adjust the 3 MAF tables to 0 in the area that you want the MAP sensor to be used. If you want to tune the MAP tables, you adjust the MAF tables to 0 in the areas you wanna tune. Since air flow (volts) is related to load. Then when you are done tuning, take the MAF tables back to what they were.
