Seawulf, thanks.
Swazo,
The PCM must be able to compensate for temperature changes. If it is a -10F Janurary day or a 180F August traffic jam day. The only way to do this is to take readings from the IAT and bias the readings from the MAF. Everybody is just flat out bitching that it won't work right. From what the Focus guys are doing, it sure seems to work. Is there proof that it doesn't work? If so, what temperature was the air when the readings became totally inaccurate?
Personally, I have seen 180+F intake temps while using the CTA intake in the summer. Nothing blew up, but it sure ran like crap. The PCM was obviously pulling all of the timing due to the insanely high intake temps. From that info, we can tell that the MAF can do it's job up to 180F.
