I got an idea from APR's tuning (Audi tuner for those who dont know). I dont know if this would be possible with the xede, but I was wondering if you would be able to design a "valet" map which the driver could set when handing the keys to a valet parker. I hate those guys. Just thinking here, but a 3k redline would be nice, and maybe like 1psi or something rediculously low.
I have no idea if you are capable of doing this with the xede, but I feel positive that I am not the only one who would like this option.
