Anyone pulled their power steering fuse?

[detroiter]

Has anyone pulled their powering steering fuse? And if so, what's
your opinion on it?

I decided to try going without mine for a while today and honestly,
aside from the much heavier steering feel, the car feels multiple
times better in my opinion. It seems much more planted and it doesn't
have the left or right wandering that's so typical. I might just end up
leaving the fuse out and call it a day, the driving feedback seems
much better without it than with it.

I have. Heavy steering at lower speeds, but it is quite nice on the highway. I let go of the wheel on a long straight stretch and must have went about a mile before the car began to drift a bit. I put the fuse back in because I really like the EPS around town. If I was to take a long trip I might pull it back out. It is nice that such a mod is so easy, and there is no cost.

I've had that disabled for a long time now -- I like it. Most people don't like it.

Even better is to also remove the servo motor from the steering column; I plan to get to that pretty soon.

Is their any possibility of hurting anything by driving without the p/s fuse plugged in?

You won't hurt anything having it pulled.

I have done some experimentation with fooling the P/S ECU and will eventually have a product to offer which allow configurable disabling of the EPS. Where, you'll be able to select options like having it on-proportional or on-full at low speed (<5, <10, or <25 MPH) and off completely at speeds above the configured threshold.

That sounds WAY COOL.

subscribed..this is interesting..but wouldnt this just gets rid of loose steering on low speed under 20km/hr higher should still be the same wouldnt it.

now where would this fuse be.. maybe i can rewire it to make a switch for it..

If it is plug and go. I'm in.

At higher speeds the EPS is still proportional, which is what causes the wander and inconsistent feel. At low speed with no assist it can be pretty hard to steer. My idea is to flatten the response on both ends so that it feels the same through the whole range.


The fuse is under the hood, but you could do the switching on the large power wire to the EPS ECU.

cool.. got to try this..thanks

I've driven around a bit more today without the fuse and the wander is definitely gone from what you'd normally expect with the electric powersteering running in place.

Now does the electric powersteering compensate to each of the front wheels? Like for example, god knows this car has no torque but sometimes if you nail the gas at a lower speed and the car really takes off, sometimes it has the reponse that your car is "pulling" to the left or the right until the torque lets up a bit.

Since pulling out the fuse, when nailing the gas hard, the car pulls straight as an arrow with now feeling whatsoever that it's trying to put power seperately to the left or right wheel.

There's a torque sensor on the steering column. The problem is that it can't tell the difference between torque applied by the driver or by the road.

is there any other difference? its not like on older cars where pulling the belt will give it more power, i know. Maybe just more stability in voltage or something lol

The main idea behind EPS is not wasting power/fuel, driving a pump when it is not needed, so it is actually pretty efficient. When you are steering like crazy at low speed, is when the EPS motor draws the most current, so that is where you'd notice the biggest power gain from eliminating that load.

getting more interesting..

OK i tried taking the fuse on etcs 10 amps but the car wont stay on itll crank but it drops the rev to zero.. does battery have to be unplug too.

It is a red 50 amp fuse labeled EPS. You do not have to disconnect the battery to pull it out.

oh maybe i took out the wrong one thought its the etcs.. now i need to find eps..thanks

what does s-lock stands for its missing a fuse in it..
