MAF sensors - Tested Sensors and Known Transfer Functions

Post by Simon@FutureProof »

Posting a list of sensors we have tried and ones that we have known curves available for.

I personally have tested the BMW M50 Bosch sensor and Russian has tried a Bosch VAZ sensor. This leads us to believe that most common Bosch sensors will work electrically with just the 5v signal sent to an analogue in.

Miata NA AFM sensor has been tested OK, (yes the trap door one) - PN MAZDA B6S7-13-210A
Miata NB MAF sensor is currently not great (08/05/2020).

Known Transfer functions are available for:
