Bypassing R32 Speedo Cable Heavy Steering

[sean133]

Want to know how I can bypass the heavy steering in my r32 has anyone done this by simply wiring in 12v to the plug in the rack?

My speedo cable isn't attached so Its normal steering until about 2 mins into the drive it goes heavy

And no I can't just re attach the cable as I have a 25 box and am waiting on a conversion part to come in and I want no heavy steering for matsuri in 2 weeks.

I've been searching and the most I've found is that someone said it can be done by some wiring.

Any other ways to bypass it without removing the solenoid and blanking it off completely?

Thanks guys

This note concerns me.

Does the solenoid normally run at full 12V or not?

I will be giving mine 12V at all times so will report back on how it goes.

I'm going to try it tomorrow but that note does concern me too

Makes no sense. Surely it can be bypassed

Driftings gonna suck if I can't get it done in time

I thought the change from low to high power assist was a hard cut but perhaps it's not.

Perhaps it alters the duty cycle of the solenoid to give a smooth transition, thus variable power assist?

If this is the case, I can understand why they wouldn't want the solenoid activated constantly.

I think you can remove the solenoid from the ps rack all together and it fixes it. But I'm not sure about it all really yet to go fiddling with it all

If anyone is interested, wired in a converter, took 12v from elsewhere, converted if down to about 6v, then hooked it into the plug next to the fuse box

Steering is now amazing all of the time

I agree with jiffo on this one, in that, wiring in constant battery voltage will eventually burn out the coil. Stepping down the voltage is a good idea, and should increase solenoid life.

I can't comment much as I don't fully understand it , my mate was the brains behind it.

But if I'm correct 12v would make the steering feel rediculously light, or heavy. I forgot.

We tried a few different settings as there are 5 settings on the converter.

You could wire in a dial/switch and change it to your liking however I'm happy with how it feels at 5v so I didn't.

[sean133]

And your right 12v probably would do that.

I shot this question to a pretty clever bloke on the UK forum and he suggested a 12V PWM running 80% duty cycle at 200Hz.

Then I did some Googling to find out what a bloody PWM was and surprise, surprise it's not all that difficult.

But if your reduced voltage works, then that's good.

Oh nice haha
