The Monthly "My Car is Running Bad" Thread

Unplug your MAF and see if it will rev.

Granatelli MAS doesn't have baro, iat, or any of that jazz. The arc2 itself sends out a 68F and 1bar signal to the ECU, which is a fixed value that doesn't change. I am 0% confident in the ECU rebuild, but I'm not counting on it being the problem.

I have heard some grumblings about AVPRO. Enough, that I decided to try Auto Velocity. I believe some people were very p oed about AVPRO service, or lack of.

The Granatelli sounds pricey, is it old? I guess even the new ones can go bad, but you need to trouble shoot it. You could prolly get a working OEM MAS from GZP (or whichever used parts place) for pretty cheap (30 to 50). The unplugging will get it in a limp mode IIRC but is inconclusive regarding if MAS is actually failing.

edit...ECU does look okay
