ABS systems are supposed to activate when the speed sensor at each corner notices the tire slowing down faster than it is physically possible for the entire car to slow down. When it reaches a threshold, it releases brake pressure to that corner until it senses some acceleration back from that tire, immediately after it lets it decel again until it reaches the threshold and the process starts all over.
I don't think our system is malfunctioning, in fact I think its working too well. It just thinks its going to loose traction immediately after it reapplies pressure. I think the parameters of the ABS system are simply too conservative to be taken on the track, problem is that if they were what we wanted, then we would have inexperienced drivers (read: the same idiots who crash when they turn vdc off) crashing in the rain all the time.

So put yourself in the shoes of the mfg, they would obviously rather a bunch of us enthusiasts bitch that we can't use our cars on the track that well, than people crashing and dying.
It happens to GT3's and Exiges all the same. The only thing we all really have in common is that the ABS system needs to be there to keep people in one piece and needs to undergo rigorous testing to meet standards.

At the same time, I realize that if the system were working properly, it should detect a point in which the tire deceleration can in fact keep up with the car's overall deceleration and stop the ABS system. If the ABS were programmed for big sticky tires such as the ones we have stock, that should minimize the intrusion of the system. It would allow for a more aggressive discrepancy between car decel and tire decel. I think thats too expensive though, to develop a customized ABS system specifically for this car and specifically for us track goers. They would rather probably use the same system as they do in the sentra, maxima and cube. Not to mention the problem again becomes; what happens when that same car is in the hands of soccermom late for practice in the rain?

The only way I can see us getting around this problem is turning abs off or having a system that is designed to allow more aggressive tire compounds. As someone already pointed out, that option is the BMW system that is $15,000.

I wish we had some sort of "Track" button that would switch us to a more aggressive ABS tune. I'm pretty sure Ferrari has such a system implemented within their manetino steering wheel system, but that's why they are $250k.

Anyone ever heard of a way to reprogram your ABS parameters?

In other words, I hope we find something punctual that is specifically causing the ABS to go and remain in icemode, but I have a feeling its just the system doing its job in what it is programed to think is a "complete panic stop". I can guarantee you all that the guys with GT3's out there, who have a little bit more resources than most of us do, (I said most, congrats if that doesn't include you) would have found a fix for this already if it were a hardware malfunction.

Just my .02 and on that note I will also add that I'll be looking for a punctual issue just like you guys. I'm just a little skeptical considering the facts.

EDIT: by this logic...folks with BBK's and stickier tires might be more prone to going into icemode. Maybe we need pads with less initial bite or less brake pressure. I'm just throwing ideas out there that might make someone put two and two together and say "Aha!". Not to mention it should happen less and less and not more and more as our crappy stock pads get hot and begin to fade, but that doesn't seem to be the case either.

Does anyone know what the BMW system replaces? Do they mention any components that hold up better to heat??
