Bmw e9x m3 Abs sensors To m1(solved)

[karel021]

That's actually normal, these sensors use an encoder in the bearing that allows them to determine direction of rotation. You should be able to filter it out.

Okay

i did Pm you.

if you have any drawing or some sketch how you wired them and also what resistor you used.

then we can try it

A short update.

the M3 sensors wont work.

Tried them in all different ways.

however for the front sensors its possible to use any other e9x sensor as long as they are not M3.

they will fit and get a signal from the orginal m3 hub.

trying to work a custom solution for the rear

An update

We got it to work

Not with the m3 sensor but one other sensor that fits good


Does anyone know how many teeths the wheel have ?

Summary.

The stock abs m3 sensor sends a pulsetrain of 6-7 pulses so it hard to translate.

In the front a stock 320d sensor Will work. Fits without mods.

In the rear we found also a working one that fits.

Tooth are 48 per revolution

Will update with motec settings when it will be up and running .

Just a simple question,

Do you still have the ABS module fitted?
It sends the individual wheel speeds out via CAN in 1 message and there should be at least a single wheel sent out via a wire with 1 pulse per rev.

nope i didnt, i think it would be easier to have that still in the car.

but im buildning a new car now with custom uprights so i will put a standard sensor there.

i got the M3 hubs to work with a sensor from an older 5 series.
