Nobody uses that. It's a pain in the ass and gives you the SUV feel. It looks like most folks are putting in a potentiometer and adjusting the force feedback manually.

You take the rack, and since you are done with the rest of it, I guess I'll do something with the motor.

The nicest thing about EPAS is that when I change lanes and the new lane is an inch or two higher because it's freshly paved, the wheel doesn't jerk out of my hands.
Oh, and if EPAS saves 1 mpg, then it must be from less parasitic drag on the motor, which means more power at the wheels.

Electric steering and brakes? Controlled by a computer? In a wifi equipped car? Criminals better be cautious when choosing a getaway car, big brother will take over the controls and drive them straight to jail.
Or they will control your speed on the interstate, slow you down when approaching construction zones, track you to your drug dealer,
Naw, I'm just a little paranoid.
Or am I?

I read little more last night about some of this. It appears that most folks are quite happy with adjusting steering feel manually.
I would imagine that a similar method could be used to dial the brakes in to your firmness/likeness. It will definitely require some method of being able to "set" the piston length (it has to know how far to actuate the MC or what the limits are). I suggest TWO potentiometers for this. One to limit max travel of the actuator and the second to increase and decrease the push-back.
Once you got these two set, you probably wouldn't need to touch them again.

I'm sure it can be done. You'd just need to design in failsafes so that if your electrically operated brake booster fails, you still have brakes.
At least with steering, you have a physical connection to the rack still.
Ford puts the motor on the rack. Would be interesting to see a fox/sn95 rack like this with variable assist levels. I doubt the aftermarket would manufacturer something like that. Too much liability.

The electric brake booster builds pressure in a reservoir. If the pump goes out you still have time to stop. Plus, from what I understand, the brakes would be similar to manual brakes in the event of a complete shutdown of the booster system.I'm sure it can be done.

Bmws have EPS...You can bet that the loyalists btched loudly when they made that choice.The steering in our cars change in quickness and effort when you switch between comfort, and sport. Since BMW made the change, only the dyed in the wool purists still btch.
Having driven a '12 X5 w/ conventional hyd power steering, it's plain to see why they did it. It was a heavy, medium effort steering feel...They are courting the female driver now,...With EPS, steering a 5000 lb SUV can be as easy, or as "in touch with the road" at the touch of a button.
It saves significant weight, and reduces power drain as a result of one less belt driven accessory.
I should convert....I've got a whole pile of mashed potatoes on my plate as it is.
Yeah, I saw all hell breaking loose over there again. So long as it keep you off the streets at night.
I would much rather use an electric power steering pump like something out of the Toyota MR2 or perhaps an MBZ unit like the guys building Project Binky (check it out on youtube, those Brits are good and nuts). With a good electric power steering pump you can take load off the accessory drive and still keep your hydraulic systems alive. I looked into this at one point but there wasn't a good way without building your own microcontroller based system to change power assist relative to speed. It also gets a lot more complicated if you want to do a hydroboost and power steering if you want a variable assist system. I didn't get into figuring out if you could run that off a single pump or if you would need two pumps.
Also, someone mentioned needed an electric rack if you swap to a coyote, this is not correct. There are brackets to run a power steering pump off the new 5.0 accessory drive so you can still run hydraulic systems of you want to. I have a friend that swapped a new 5.0 coyote into his fox body and still runs a hydraulic rack.
