Modern hot film MAFs are no more or less prone to failure than any other sensor, including IAT and pressure sensors.
Incorrect. If that were true I wouldn't have a stack of those bastards from replacing them for random side jobs. Car runs like crap? The go-to is always unplug the MAF.
Either way, why all the negativity toward someone trying to do something different and new with the platform? We have obvious expert trolls who like to strut around professing their expertise without bothering to share any of it. I learn by doing, and I will do this. Why? I have a need to run a filter directly on my big single and refuse to pay a massive premium for blow through MAFs that require massive amounts of time tuning to get right. Speed density, which is NOT a hack by any means, is my answer. Whether it be ME or complete standalone. The former is within my budget at this time so that is the route I intend to take.
