[Audipwr1]

Anyone running a Volvo pump intelligently with MaxECU

Big list of pumps that work: https://www.maxxecu.com/webhelp/can_...rsteering.html

Wondering what is best for a RS2 / ABY S2 rack?

Thanks!

Good find, I already have an Opel Astra pump, but now I am thinking of using one of these Volvo, as Maxxecu supports those.

How you liking the Maxx? I’m in the planning stage of building a car and leaning towards using it

I am looking after the Race version of Maxx, to have plenty of features which could be used, but otherwise ecumaster black was my second option, which is cheaper but looks good too.
Ask your tuner, which ECU is best for him.

Anyone? Would love to order the right pump the first time!

Maybe give it a try to post this on the s2fb group. I guess that forum is not as visited as before a few years back.

Yes but which one is best for our platform?

Audipwr1 Did you bought a Volvo steering pump already?

I installed the 31202520 pump in an S6 AAN. With original Volvo holder. Connected this to the Maxxi and rebuilt the pump holder a bit and it still works quite well. But as I said, I have an AAN, not an S/RS2.

Prosac Did you manage the pump inside maxxecu? Like slow speed turning (more force) higher speed (less force)? I am curious if you managed this.

Hi, I connected the pump to the Maxxecu via CanBus. A good help can be found on the MaxxEcu Website. For the correct settings of the pump you have to try and drive something. It is effective like a servotronic.
