Abs Off Switch

[Yoda]

Everyone probably knows that a human can out perform an ABS system. So....has anyone managed to design a switching mechanism to diable the ABS from the drivers seat?

I know you can pull the fuse in the panel in the dash but this seems to upset the auto transmission, and the one under the bonnet is a pain in the a.se.

Any idea's out there???

Hey Yoda.....

If you simply pull a fuse the computer will recognise that no signal is present from the abs sensors and go into limp mode......

I've been trying to get mt hands on a workshop manual on cd - hopefully this might help shed some light on this subject as well.....

Who knows? Might even be able to set up a line-locker if we can sort this out (for those who own manuals)

Should be able to find out the required voltage signals from the abs sensors & work out a little thingymajig to confuse the abs processor???

Would you be able to turn it off with the edit? You seem to be able to do anything else!

In an emergency stop on a slippery wet road? Methinks not.

I've been to several happy days at Mt Cotton on both the skidpan and the LVMA and can attest to the performance of the current system. For the tiny bit of advantage you may get on a track, then maybe, but for everyday use I cant see any advantage.

Just my opinion mind you......

I was talking about the track. Are people of the oppinion that the system is that good that it is OK on the track?

You are right, from a technical point of view, a human can out brake abs. But the catch is, most of us are not good enough to do it. & the other thing is ABS gets it right 100% of the time, humans can never hope for this. As far as switching it of, simply unplugging a wheel sensor or switching a main power wire would do the job. Problem is it would make it unroadworthy & would think no insurance company woul;d cover you in case of accident. I have wiring diagrams & think ABS system are fairly simply, but they do not get controlled by the PCM so edit cant help. However, I dont think many people will give you the diagrams for this reason, is a little dangerous & probably even puts us in a situation where liability may come into play.

A couple of points to make about Ford ABS.

1) it is not really suitable for a track and or racing situations, a human can vastly out perform it.

2) Ford use the ABS to balance the brake bias (I.e. front to rear). The rears have far too much brake preasure and will lock first. If you bypass the ABS you must do one of the following to restore a more natural brake balance. 1) fit a non abs master cyl, 2) put an inline brake preasure reducer in the rear line or 3) use vastly different pad material front to rear.

3) Simply disconnecting the existing control unit, either electronically (fuse etc) or by bypassing hydraulically will lead to worse braking performance and increased stopping distances, due to prematurely locked rear brakes.

If you were racing it in the Production car series or plan to dirt rally, then I could see why you would want to do this, but for the odd club track days the ABS does not get in the way.

I would leave it alone and make sure you only drive 8/10th. Any higher and it may all end in tears.

The 4 channel system on the T is very advanced, 99.9% of people could NOT outbrake it.

In both my XR8 and XR6T I can tell you ABS is applied well before the wheels would loose traction. It would be the thing I hate most about my XR, that being said all new cars are the same, it’s not like the Fords are any worse. (in fact the SLKs are BAD)

If it was an option to not have ABS fitted I would have ticked that box.

Thanks for that info xr6_prod. That is what I have experienced in a track situation. So what is it that you have done in your car for racing or do you have to run the ABS?
