Aftermarket Upgrade Sensor Data

For some modifications its useful to change already existing engine sensors to upgraded ones from the aftermarket or even other OEM parts.

The most common change is propably another MAF sensor so the ECU is capable of processing more airflow. But also an M50 manifold swap requires you to change the IAT sensor data because of the different charactaristic curve.

All temperature sensor voltage data (Volts -> °C) is listed together with the pullup resistor value for MS42 and MS43, keep that in mind when you want to use data from this site for standalone ECUs.

We try to find out sensor resistance data so that you can create your own voltage data for non factory ECU useage.

The term (X*0.0048828125) is used by MS42 and MS43 to convert the ADC input signal into voltage. Just ignore this to get the voltage conversion.

Mass Air Flow Sensors

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 the Audi S4 B5 series. Sometimes you will also find it even cheaper under the VAG replacement part number 078906461B.

The sensor itself is a Bosch HFM5 slot-in type and comes premounted in a 73mm inner diameter tube.

This data is untested, but calculated from the original 38-point scale HPX provides on their website.

According to HPX both grounds can be connected with no negative effect on reading accuracy. So you only need +12V, ground and the MAF output signal to adapt it to an MS42 or MS43.

HPX MH95 2600 MAF Scaling.png

HPX MH95B-3000

HPX MH95 connector

This data is untested, but calculated from the original 38-point scale HPX provides on their website.

According to HPX both grounds can be connected with no negative effect on reading accuracy. So you only need +12V, ground and the MAF output signal to adapt it to an MS42 or MS43.

Bosch MAP Sensor 20-300kPa (0261230119)

Bosch MAP Sensor 0261230119

This sensor is perfectly capable of running an M5x engine in speed density mode because it can measure as low as 20kPa which is heavy vacuum. The push-on tube connector makes it perfect to be connected to the M5x manifold nipples and mounted remotely. Or to check compressor inlet and outlet pressure with quick taps.

BMW TMAP Sensor 25-425kPa (13628637897)

This TMAP sensor is used in BMWs B38 and B48 petrol engines and perfectly replaces the stock sensor of B58 and S58 intake manfolds if you have to read higher air pressures than the original 250kPa sensor.

Its is labled to 50-350kPa by BMW ETK, but the pressure element is capable of measuring 25-425kPa making it perfect for speed density (MAP) useage when you swapped in one of the mentioned air-to-water manifolds.

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.
