Can anyone tell us how it operates / how it was disabled?

The speed limiter is preset in the PCM on a part that is known as the VID block(Vehicle Identification Data).This contains 5 peices of vital information.1/Speed/Cruise control 2/Speed limiter 3/VIN number 4/Fuel octane rating 5/Rear Axle Ratio/Wheel & Tyre size.

There is a way of reflashing the PCM using a WDS machine where the VIN number and Speed limiter are permanently removed. Because the VIN number is removed it is very easy to tell if this type of reflash has been done. Basically no VIN=No warranty and a real kick up the arse for the dealer that reflashed it.

Cheers fordtech, but if you've modded your T it's no warranty anyway isn't it? If I mod, I'll be wanting the limiter removed.
I have no interest performing "sneaky" mods or hiding anything I do.

If you were unconcerned about losing the warrenty could you instruct the service department to remove it. Would they have to respect your instructions or could they just not do it ?

Geea.

geea> I reckon you'd have trouble getting them to do it.

Imagine the outcry if they did and the driver then went out on a public road, maybe not even in the NT, :lol: and for whatever reason crashes and dies at a speed in excess of what the limiter had been - the dealer would have his ass sued from here to eternity and back, and maybe even FoMoCo as well for making it possible for it to be removed in the first place.

I'm thankful the only artificial limiter my car has is the size of my GOnads :blink:

I would reckon with the factory tyre specs having a speed rating of around 240kmh max it would be illegal for the FoMoCo or any of it's dealers to remove the speed limiter, even if you didn't have std tyres?

It's a difficult question guys. We have been removing or changing speed limiters on Ford since its introduction with EB/ED as well as C'dore, WRX Skyline etc.etc.

Our customers fill out a contract in their own hand which states (in legalese) that this is for motorsport use and that they will use Z rated tyres etc. etc. We have been fortunate that no one has been silly enough to do something stupid on a public road or otherwise, that would test the contracts validity in a court of law.

We have a duty to be responsible in our modifications for customers as well as providing real motorsport alternatives to go racing with.

Try considering that one for a bit for me??? :blink:

Cheers

Because every time I read these forums I just want to get out in the car and take it for a spirited drive. And if I go and do that I just know I'm at a great risk of damaging my car, me and anyone else that is out there. :blink:

Why did you buy a turbo then? A NA xr6 handles the same without the extra power, but then again, why bother with that? Go and buy a normal XT it goes the same as a NA xr6. But hang on, you should get something a little slower and more fuel efficient - how about a Toyota Prius ???? Give that thing a spirited drive and it shouldn't cause you as much angst..... :lol:

Hi Lachlan, is Chiptorque able to disable the speed limiter in the "T" yet, either through the Xede or by other means? If so what is the cost please?

Geea. :bigdrool:

The official words:

Not at present for BA!

This is nuts. driving at 200Kmph is a feat many if not nearly all people can perform, given the right attitude, training and knowledge.

I've driven many cars, at well over 200 Kmph, yes on public roads, even in the rain in high traffic, dual carriageway.. Completely safe and legal. Even at night, even, in when it gets a little icey. Not all of these were high powered performance cars, some where dinky little hatchbacks with 1.6L engines, fwd and 185 tyres.

You don't suddenly crash when you hit 180 or such a speed.

<Snip>

Disabling the speed limiter on the BA falcon should be simular to any other speed limited car, such as a GT-R or M3 or what ever, intercept the signal from the speed sensor in the gearbox, and using a varity of methods change it before it gets to the ECU.

Frequency divider, frequency generator etc. It isn't expensive and you can do it yourself or buy a kit. With a simple frequency divider, you can raise the limiter from 230 to 460Kmph hence not a problem anymore..


I too have driven extensively in Europe and I would concur with some of your statements when sensibly trained and experienced drivers are concerned.

Good luck with the gearbox speed sensor frequency divider!
