E46 m3 abs

[Bimmer_man]

Can you in a sense update your ABS by switching the E30 one with a E46 abs? Im curious cause obviously the E46 ABS is more advanced and well better.

I sort of remember someone asking about this and the answer was that it was possible, though E46 hall effect wheel speed sensors were required. It would be a fair bit of work.

a long time ago turner or bimmerworld (forget who) offered a complete mostly bolt on kit to retrofit e30s with e46 m3 abs. IIRC the cost was around 3k for everything that was required

Ah.... something I can sink my teeth into.

The sensors on the E46 M3 ABS (Mk20 or Mk60) are not Hall or VR sensors, they are a third type.

They offer directional information, as well as self check when not even moving.

These are the blue connector sensors.

One would need to convert several several items over from a Mk20 or Mk60 system, AND keep in mind its designed to work with brake bias ratios quite different from stock E30 car's, and certainly without a brake bias valve in the rear circuit. You'd also have to add brake lines since its 4 channel.

I would love to have "modern" abs in an e30. I wouldnt pay more than 500-1000 $ to do it.

4 channel would be lovely.

Biggest problems other than installation and parts would be with the wheel speed sensors, and tying the modern unit into the dme/ finding one that is standalone from other systems.
