EPAS Terrible Shudder

[cyclerick]

I run 315/35/20 and 275/35/20 pilot SS and have never had the lights come on.

So, Terry, are you aware of the possibility of the stock racks being reprogrammed with the same FRPP-M3200-EPA program?

I have a guy (customer) working on a very cheap solution, but it would be more along the lines of "rigging".

Any news on this?

Would love to do poly bushings but too worried about this EPAS problem. Don't have 1k to drop on new rack.

I installed poly bushings in my 2013 and haven't had any issues with my EPAS.

I was convinced that my shuttering was due to cheap tires but I'm on Michelins now and it's still there. Very unusual b/c it's not consistent. In other words, if I'm driving to work, sometimes on the same road it will shake like a paint can getting mixed at Lowe's, and other times it's basically smooth with no shaking at all. It's kind of annoying but not enought to make me not like the car or enjoy driving it. I would love for a fix though other than a new FRPP rack for $1k

Mine had the shudder when the temp was warmer and the steering was warmed up. It never did it when the car was cold or the temp.

Did swapping to larger-width wheels and tires cause an issue? I want to run wider tires, but I'm terrified of making my car undrivable. And that shudder of death equals undrivable in my book.

I went from stock 19"x 8.5 x 245 on my CS to 20x9x 275f and 20x11x315r with Steeda Sport Springs and D specs without any problems. It was only after the aftermarket front A arms and bump steer kit did I get the shudder like in the video. Once the bump steer was removed, the shudder went away. Now a year later, I just did 14" F and R brakes and I've got a vibration at 80+ mph. Was this caused by added weight of brakes or do I have a wheel balance problem??? Will check balance again.

I run 285s on all corners without an EPAS issue. All the front bushings are stock, however.

Is it possible for any of you guys to test the EPAS by disconnecting the CAN communication and tell how it feels/compares?

I just went to check that the data connector has switched power too so disconnecting the plug just won't do it and is going to be more complicated than that, forget about it.

Dang, one year later and this thread is still going strong. I figured they'd have an update by now.

They do. It's called the Ford Racing electric steering rack, it's "off-road only," and it costs $999.

Yeah, kinda like Ford's fix to the MT82 is that they sell the T-56 Magnum XL in the FRPP parts catalog? Some days I wonder if I would have been better off just building my 4.6 3V or doing an engine swap than dealing with all the cut-corners of the 11+ S197s.

I wouldn't say corners were cut. The '11+ chassis has a lot of improvements over the earlier ones. Though I do wish the manual transmissions were built in a first-world country and that Ford would allow me to install the racing EPAS unit's code onto my stock rack, since firmware is the ONLY DIFFERENCE between the two.

I think they did cut a fair amount of corners on the 11+, but for the sake of keeping the thread on topic I'll leave it at that. I will give you that there are a lot of improvements as well.

I honestly don't care that the transmission was built in China - they just should have kept the QC in check and NOT used the inadequate shift linkage for this application. I also wish I could just flash the EPAS rack with the proper firmware. I'm surprised nobody has "engineered" a workaround for this yet given the cost of the replacement rack.

 

[Sky Render]

I don't think there's a way to reflash the rack. At least, the dealers can't do it.

 

[choate]

It's unfortunate we can't flash. I will just wait and hope mine doesn't get worse and maybe someday there will be a fix. Luckily mine is not as bad as in the video but it's there for sure. I had the car up to 100 one day on a back road in the country and the shuttering didn't get worse at higher speeds though so that's good for me. It almost seems at it's worst between 70mph and roughly 85mph but if you keep going it basically just stays the same or slightly gets better. What is ridiculous is when I rented a car recently I got a Chevy Cruize and it was smooth as glass.

Anyone with 20" wheels and a big brake package install a new rack and eliminate the shudder at 80 mph?

Bit the bullet and ordered Boss 302R M3200 EPAS for early July install. Tired of the EPAS shudder

Any tips on the install? Believe have to raise motor less than 1 3/4" to reach bolts that are locktited.

I now have the shudder but only when advancetrak is turned off. If the nannies are on then i have no shudder.

My car just rolled 19K and no shutter.
