NA MAF to FI MAF; is one of the harder processes to do IMO.

But I think the primary reason for that is the "newness" of MAF based Tunable EMS's - which are basically Flash Tools like the Cobb AP.

The upside is that since MAF = MASS of air; you don't have to account for heat from FI for fueling purposes a.k.a. Loss of PPO2 due to heat (you do for timing obviously; as a super hot intake charge will be more likely to detonate).

I am pretty darn sure that MOST of the factory boosted EMS's (MS6, MS3, EVO, STI) - have both a MAF and MAP; which would a really good way to tune; hence why the Oem's use them both.

I'm not arguing, just surprised. That's the reverse of what I would have thought. Since MAF could already (to some extent) account and adjust for the added flow from boost, I figured that an OEM MAF would be easier to mod to FI. I thought a MAP system would be pretty much fixed based on throttle position, temperature and intake pressure but only up to atmospheric. So you'd need to start all over to move to FI. In any event it's been fun to try to think it through.
