Hey what's up? Actually, I've tried that, and it doesn't seem to be working. How long do you have to wait after the sequence. My car is a '99, and I've been told that it doesn't do the keydance. Let me knwo cuz I'm really interested to know if I broke something. The car is lightly modded, but I do run nitrous, and an aftermarket chip. Each time the CEL comes on it's during hard driving, but no nitrous injection. Anyway, do you know if this works for a '99???
