Several "problems"... hope someone can shed some light !

Hey !

Well, I have several issues, at least I think they are issues... I have a SKI Supercharged 330ci, with the asatronic piggyback.
I think my MAF may be dead or close to that (even though it doesn´t throw a code). Why ? Because of several issues... I don´t feel much difference when changing the ASAtronic setting from 10 to 0, if any difference at all (and we all know the ASAtronic works with the MAF sensor), I´m getting 19 MPG with fairly spirited driving (this may or may not be normal, you guys tell me. From what I´ve read here, generally most people get around 22-24 MPG), and, I tried unplugging the MAF sensor, and started the car, it started normally as always and didn´t throw a code either (didn´t drive it, but will tomorrow with the sensor unplugged). Finally, the car is cutting my RPM at like 5800 RPM or 6000 RPM, instead of 6500 RPM, which is where the factory rev limiter is supposed to be.

What can be causing all this ?

Thanks !

Interesting...I have a sk+ on a 330ci 02. Just change the MAF afer engine light came on and car seemed under powered. Got it read and was told it was the MAF. It seems ok but a bit lumpy when you start it. My Asatronic is just a box and doesn't appear to be adjustable. Have you got any pictures of yours???

Well, I don´t currently have a photo of the asatronic, but its just a little metal box with a kind of a knob that looks more like a screw on top of it that you can change to the left or right to lean or rich the mixture.
