I know this thread is pretty old, but the link is gone. Any link to a working page? I would like to clean my AFM.

You won't see a power increase on an otherwise stock m20, but responsiveness improves drastically, since the barn-door is eliminated.

... i wont say anything about the used parts.. But uhh how bout a AFM to a Mass airflow sensor swap instead? How hard would it be? Is there a power increase?

You need some kind of ECU system that can interpret a different reading, from a different type of sensor (AFM to HFM)

SMT-6 is often used for an HFM conversion.

It's very easy to work on these cars. It's just people do stupid things just because they can. That isn't directed to you.

The fact that the E30 is easy to work on makes it just as easy to screw up. If you think the E30 is hard, try changing the head gasket on a Mk1 Mini. :)

Believe me I know these car are easy to work on... I was just making a funny.

I'm thinking of installing an A/F Mixture guage and using that to tune it. I may go with the M30 AFM swappy swap.

If it were that easy to work on these cars there would be no r3v.

The one that came with the car was trashed. New one costs WAY too much.

NAPA sells a reman AFM for $100US. Should come with a warrenty. Might be worth a try.
