Ride height sensors for magride delete cars

[mavisky]

Recently moved to MCS coilovers on the car and was curious if there was any reason to leave the front ride height sensors bolted in place since I run with stabilitrack disabled. Re-locating the sensor would allow me to utilize the softest front swaybar adjustment point on the front end. The only real concern I would have would be ABS and what role the height sensors may play in factory ABS algorithms.

You can put them wherever you want. Just keep them connected. Ride height sensors aren't used for ABS.

Sounds good. Now to find where to tuck them out of the way.

I suggest you do a check ride with the sensors disconnected from the mechanics before you relocate them. The VDM is supposed to check the sensors for rational movements, and if not detected, it's supposed to send a DTC out on the CAN bus. If the IPC hears a fault in the VDM, it'll block the driving mode selection and set it on "Street" until the DTC is fixed.

Now, I say "supposed to" because I've seen the VDM DTC list, but I've never experienced the problem. Maybe it's not a problem, but best move into it stepwise.

I know I had an issue at one point on the stock VDM when I had a ride height sensor come disconnected. It did kick stabilitrack back on and set me back to Normal mode a few times, but it was always triggered by a weird situation on a course we would run where there was a steel plate for the water outlet of their wet skidpad and it would cause the car to try and do weird things dynamically.

When I had the DSC unit hooked up you couldn't even access the VDM through something like Forscan. A test ride with them physically disconnected from the suspension arm isn't a bad idea I suppose and easy enough to do.

Why run them at all? You can delete the ride height sensors with these: https://shocksims.com/shop.html#!/Multi-Piece-Kits/p/553905070

It may throw an ABS code in the DTCs but I have not noticed it any issues with ABS.

Because just relocating them is cheaper than purchasing an eliminator.

If you had the DSC connected, then the VDM wasn't.
