Does ABS know which way the wheels are rotating?

Or does it just know how fast?

Reason being I want to keep the ABS from my donor but I also need to put the front hubs on the wrong sides as the steering arms are behind the wheel centres.

Obviously this means that the front wheels will be going in reverse (compared to their original fitment on the donor).

I believe the direction is irrelevant because the sensor records the number of 'teeth' that pass it.

I dont think it matters as they just measure the pulses

just the pulses

Personally, id bin the ABS. If it goes wrong, youve got no (or little) support, and if youve grown to rely on it and it stops working, you could hit some doddery old git overtaking on a blind country bend that nearly happened to me today. (no, i wasnt speeding, and i had the kids in the car!!) And yes, i did swear at him!!

He may not have the choice if he's using the original ECU, it might refuse to start the engine if it thinks the ABS isn't working

thanks guys these are just the answers i was hoping to hear. I want to try and keep the abs, it looks like a fairly simple system but yes it is tied in to the ecu, check control system etc. Which is fine as i have always intended to use as much of the donor as possible.

ABS isn't a simple system it has to be programmed for varialbes such as weight, spring rate, wheel base.

Also just swtiching the uprights to get the steering arms to the front could cause big problems with the ackerman angles, depending on the exact design of the steering arms you could end up with a great deal of toe-in in turns which can give very scary handling.
