Title: Low maf reading at high rpm Post by: Fyzzz on June 13, 2021, 01:01:45 AM I have been tuning my car and pretty happy with the results, done alot of logging. My maf reading has been very weird, it's barley any higher than slightly modified bex file, but the car is way faster.
I changed out the maf sensor over a year ago when I bought the car. I did not buy a bosch one (some other brand). My car is bfb engine code with bex turbo and injectors. I have also installed BKR7E copper plugs and recently a FMIC.

I've tried multiple aftermarket MAF sensors and they've all been shit. Get an used or new OEM one Title: Re: Low maf reading at high rpm Post by: Fyzzz on June 13, 2021, 03:24:54 AM I tried my old maf sensor (which i knew wasn't in great condition) tried cleaning it. Interesting to see what would happen. It reads a bit to optimistic now, maybe I have to order a new Bosch sensor.

Should show up soon, interesting to see if anything changes.
