Delimiting XJR?

Some habits are hard to break. When I learned to drive, ABS was not invented yet (late sixties). Cadence WAS the way I was trained, and I still do it although all the vehicles have ABS. Frankly,....I don't like ABS. Sometimes (on the slippery surfaces especially!) I want my car to slip and slide. Years ago in MN, I owned Audi 5000CS Quatro, and that thing had a button on the dash to disengage the ABS at will. It was disengaged every winter.

I've had to find the area just before the ABS kicks in to exploit my uprated brake system, that way I know I'm not going through a brick wall...
Paramount performance here in the UK delimited my car, a .hex file was loaded and the 3 digit check box figure of 155 was replaced with 255 - oh we giggled...

ABS and traction control is good to have, but I want to be able to disengage it when I want. It is MUCH easier to steer and brake the car on loose snow/ice, without it. To really learn how to drive on the ice/snow one should practice on the frozen lake. I know many people don't have the opportunity to do that, but I lived on the lake in MN, and MOST people that live around those lakes (Minnesota - The Land of 10000 Lakes!), drive over them in the winter to "create a shortcut" and/or to avoid the traffic. A car with disconnected ABS/traction is a LOAD of fun on the frozen lake. Maneuvers and the vehicle behavior learned, and practiced on that surface, come REALLY handy on the frozen freeways/side roads.

In that case it could probably be done quite easily, maybe even with IDS/SDD...just need to plop the modified file in the right folder and then reflash the ECU...

Gearing allows for 202mph (6150 rpm in 5th)
Motor Trend says de-limited top speed of around
175mph. The top speed of the 4.0 V8 (290bhp) is listed
as 150mph, but DavidN in DE says his has been to 155mph
limited in his XJ Sport. That car, having 7000rpm of
engine, would have a higher top speed gearing wise I'm
sure. It would need 450hp to even get over 180mph though,
by my reckoning.

Cambo, do you know of anyone on the West Coast (USA) that has the SSD and is able to "raise the bar" on the speed limiter?

Why does the dog lick its nuts? Because it can. That's why I want to have the option of higher top speed. Following your logic I should reset the limiter to 99 mph.

Tirefriar, I men't no dis-respect, I love doing what I'm not supposed to do too.
but there are so few places to really stretch the legs on these cars, and CA is about the least friendly of the ones in the US.
Unless you have friends with an airbase runway to use it's kind of mute.
Around 1991 in LA I was involved with some guys that had access to light planes and a helicopter, we would drive out to Barstow around shift change time for the CHP, use the planes to check for traffic and cops and run out on I15, I've seen 190mph on a freeway for short bursts, it's frightening..and CHP were not happy, we would get pulled over on the way back to LA and basically told if we get caught by them they will crush the cars and we would spend time in jail. I relate this story for 1 reason, I've done it and it's dangerous so I speak from experience. I also did the silverstate the same year the couple in the Ferrari died, little mistakes cause big problems.
