I am building a track car based on a Focus Mk3 (2013-on). The Focus uses EPS with the power assist motor built into the rack at one side (I think made by TRW).
The problem with it is that it relies on a CAN BUS input to operate.

Does anyone have any experience of using this steering? A stand-alone signal module could be a good way to go?
If it can be made to work, this could be a very attractive unit for many project cars - easy to mount and compact.

I have used the Corsa C steering on a previous project with a speed signal module, and while it worked ok it wasnt the nicest feel nor was it easy to mount.

I can't help with your original question but has used cosa A power steering. I think that also only took a speed signal and 12v supply.

Nice and easy.

I've got the corsa b set up in one of my cars using a proper speed signal from the gearbox and the Agila / wagon r in my other car . They both have the same Mitsubishi ecu and I've fed both with a proper speed and rpm signal so they work properly . The Agila set up is half the size of the corsa with the little ecu strapped to the Column and its clutch driven so no gear drag once the assistance is off so feels quite nice and above 30 mph the assistance is based on torque input with a proper speed signal

I used to work for TRW Automotive in the EPS Division.

Maybe I can help?
