Re: Power steering fix 100% working.
Just trolled through eBay. Look for one with good build quality.

Re: Power steering fix 100% working.
The motor controller should be able to handle 40-50amps. The pump draws alot of current under load/full lock.

Re: Power steering fix 100% working.
Couldn't be 100% sure but I am 99% sure the pump is going to be PWM speed controlled by the pump ECU.
Essentially it uses your speed sensor so you have full assist when your parking but at about 120km/hr your pump is essentially turned off. In between you would have some sort of linear or otherwise ramping of the level of assist.
So putting in a pot and manually varying the speed is not really a replacement for the factory setup, so yes its working but not 100%.
My part time job is to component level repair the MCB for the Pro-Form treadmill boards. Same principal your DC motor is PWM speed controlled via the console.

Not really sure what you trying to achieve?. I'm just trying to help people whos P/S isn't working.MR2DI4 wrote: ↑13/10/18 0:03 Couldn't be 100% sure but I am 99% sure the pump is going to be PWM speed controlled by the pump ECU.

My method does work 100%. You will have a working P/S system.
You just have to set your pump speed.

Re: Power steering fix 100% working.
Id ignore MR2DI4 - he seems to argue about everything so always go with the majority.
I think it would be great (if the power steering worked in the first place - lol) to have this option of controlling the power steering via a pot but also be able to switch it to auto too.
I did look at doing this myself when i was having problems but i solved my issue which was the kmh/mph convertor not wired in correctly which affected the ps.
Still a great idea for someone who wants to control it themselves.

Re: Power steering fix 100% working.
Would be awesome if the P/S just worked.
As for using the factory speed sensor with the motor controller that would be sweet. But that's where my knowledge runs out.
People mentioned the use of a micro controller to control the pump speed in previous comments. I only have basic knowledge of circuits. I'm sure there are people on here that have extensive knowledge of the P/S ecu and its contented components.
I would love to see a solution that improves on mine in every way.

Re: Power steering fix 100% working.
Planning on doing this to my mk2, really struggling to find a 0-12v motor controller. Anyone have a link or an idea where I'd get one. Many thanks
