I have a 2019 GT that has rev match and it has failed to work several times lately at the worst time. Unfortunately since it rev matches and I have had this car since I was only 6 track days deep in 2019, I have never learned how to heal toe the car. I know the right answer is I should learn that and not rely on the rev match but we are now 8500 miles deep into track events so before reinventing the way I drive I will just swap in a DCT transmission from a BMW and paddle shift the car. For now though I would like to get some confidence in the factory rev match system. I have had an issue with this in the past where the computer shut off the rev match once the car was over temp. Since that seamed more dangerous for the car to not rev match and slide in a big brake / downshift zone I programmed the computer to not limit rpm on the first 2 stages of over temp, and it solved the issue for about a year without issue, then while at AMP I had a fuel starvation issue and the check engine light that would cause, would at the same time shut off the rev match. I figured that out pretty quick and just kept the car topped of for the rest of the weekend without issue. But now both at the end of the long straight at road Atlanta, and CMP it had some sporadic issues of not working. It is really unsettling to expect it to rev match and then when it does not you get a pretty violent slide as the rear wheels get locked up until the engine gets up to speed. The question in all this is does anyone know other things the computer will cut this feature for?
