Air Flow Meter

Post by adika »

Hello everyone, is there a way to get rid of the air flow meter and put something that will work better. I believe its the reason the car is having some idle issues and I cant seem to adjust it.

Thanks

Well, MAFs are better but I've never heard of software to integrate them to L jet. Even on E28s with chips they tend to be cranky. AFMs can wear, but are generally repairable and really do pretty well.

Check to make sure your cold air valve is working properly. It might be as simple as needing a cleaning. The idle air screw on the air flow meter is meant for fine-tuning, not to be a substitute for the cold air valve.

On my car, my cold air valve is located under the intake manifold. You will need to bleed out enough coolant (which will be a lot) to avoid a mess when removing.

Ive seen on e28goodies.com an "air flow meter delete pipe/temp sensor", i have no idea how it works or if it works, but might be worth checking out.
