Mass Air Flow Sensors

We decided to publish often used MAF sensor scalings. This will make fuel tuning even easier.

Please keep in mind that you have to apply the MAF hack to your firmware binary when exceeding 1024kgh.

Audi S4 MAF Sensor

The Bosch 0280218038 MAF sensor is installed in Audi S4 B5 series. Sometimes you will also find it even cheaper under the replacement part number 078906461B.

The sensor itself is a slot-in type and comes premounted in a 73mm inner diameter tube. Matching connector can be found under VAG partnumber 1J0973775A.

Due to the relatively high minimum pressure measuring threashold, this sensor is maybe not suited to measure vacuum, but boost only.

Oil / Fluid Temperature Sensors

If you want to use different anolog sensors, it's important to know the ECUs internal electrical circuit diagram, since the sensor value differs when you calculate the sensor voltage with a wrong pull-up resistor.

The MS42/MS43s oil and coolant temperature is measured over a voltage divider with a 828 Ohm pull-up resistor to the internal +5V supply.

Temperature Sensors

If you want to use different anolog sensors, it's important to know the ECUs internal electrical circuit diagram, since the sensor value differs when you calculate the sensor voltage with a wrong pull-up resistor.

The MS42/MS43s intake air temperature is measured over a voltage divider with a 2.49kOhm pull-up resistor to the internal +5V supply.

The M50 IAT sensor uses the same thermister as the M50 ECT sensor, which is a bosch 0 280 130 026. Bosch ECT Sensor Data

The M50 has an 1.1k internal ohm pull-up resistor. The below table has been scaled for the MS43 2.49k internal pull-up and is ready for use as is.
