Revision as of 19:26, 9 August 2022
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.
Mass Air Flow Sensors
Please keep in mind that you have to apply the MAF hack to your firmware binary when exceeding 1024kgh.
BMW M54B30 MS43 MAF Sensor
The connector and pinout is the same for all MS42 and MS43 MAF sensors.
Note: MS45 uses a different MAF sensor.

HPX MH95B-2600
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 MH95B-3000
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.

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.
