Has anyone considered running an Electronic Hydraulic Power Steering Pump? I'm considering this because I want one less thing connected to the engine for removals and replacements (because race car).
I guess the SW20 had one but its kinda pricey used (if you can find one). -------------------- -Mike

I just downloaded the SW20 EWD - There is a Power Steering "Driver" and "ECU". The system does in fact reference the steering wheel position AND vehicle speed
It looks like the system is speed based... looks like it goes to a low power (3-5 Volts) over 40 MPH and full power (11-12 Volts) below that.... The steering wheel sensor looks like it uses a pair of photo transistors which you could use to detect the speed and direction of the wheel turning. It doesn't look like there is a mechanism or system in place to try to count the these blips of light to know exact steering wheel position.. Reading the service manual I can't see any explicit test where they make sure the steering wheel sensor affects voltage to the power steering pump.. -Mike This post has been edited by qatar11: Jun 11, 2015 - 7:56 AM -------------------- -Mike
