2000 C5 and SCT X4 chip
Just a note to advise that the above chip programmer did not successfully communicate with my 2000 C5. We were able to download the latest software, plug in and receive info from the car to the device, but the device maintained an error message when trying to download our programming info. We tried this several times, talked with the tech guys all day and unplugged all fuses but the main one to no avail. Tech guys were not that helpful. They tried but didn't seem that educated. Be aware. There are other posts on the internet regarding this chip programmer and the 2000 C5. Wish we had found them before buying!
