I'm running alpha-n right now but have a Saab mad plumbed in and hope to get the setup running on maf.
I have not started tuning yet because:
Voltage reading in tuner studio withe the sensor unplugged is around 0.2v with the sensor plugged in and the engine not running I'm getting 0.95-1.05 volts. I cleaned the sensor with flux remover with no change.
Is this OK or should I toss this maf and get another?

Are you sure you don't have an HFM5? The zero-flow voltage for that is 1V, less indicates reverse flow. Blow through it backwards and see what happens.

Any updates? Did it measure reverse flow?

Re: hfm2 maf no flow voltage reading around 1v??
my wife just picked up a cabriolet to play with but have to swap out the motor, so my scirocco toy got kicked out of the garage for now, I haven't messed with it too much since the scirocco is running well with the itb's on alpha-n and sd with the map connected to the plenum for boost correction and control. once I get the boost control and eae dialed in, I'll have a really good base to use for comparison switching over to maf/eae.
