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.

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.
