AIrflow meter, Air temp voltage -> degree

[E30godz]

I wired up the SMT-6 to intercept the Airflowmeter air temp signal, and it gives me a nice voltage reading...when cruising it gives me about a 2.5 V signal but when i datalogged it and under full blast turbo boosting goodness, it gives me a .8 or so V reading...im trying to figure out how to work these into degree readings..anybody?

oh at cruising the 2.5V is (im assuming) the ambient temperature, which was about 80 degrees today.

My check engine light have stayed on since the first time the car received boost

wierd, my doesnt come on...

maybe means a shitty A/F ratio...bad enough to make the check engine come on

i think the absence of the temp sensor will keep the check-engine light on.
