C5 PCM Question I am checking to see if anyone knows which pin on the PCM of a 2000 Corvette controls the cars TCS software and retards engine timing. I also need to know if the TCS program applies a ground to that pin like it does in an F-Body or is it a different set up? Thanks in advance.

For example on an F Body there's a pin on the pinout that you apply ground to and it will trip the timing retard side of the TCS. On a 1998 f-body pcm the pin number is an r30, on the 99 and up cars that pin is r53. I'm just trying to find out what number it would be for a 2000 MY C5 PCM. Thanks

I have a '99 TA, and have ask this question alot before, about to ground or not to ground the r53 pin in the PCM.
I have remove my TCS and just elminated that wire from the PCM.
Do I need to ground that pinout? With it not being grounded, will it retard timing. I have not driven the car after I did this, cars been down now for 2 years.
Thanks

Yes, the 83 is for the absence of a Vette in 1983 due to the changeover from St. Louis assembly plant to Bowling Green. Every one of my friends calls me MrVette because I've been a Vette fanatic since I was 8. 26 now, still don't own one but it's on the horizon. In the process of buying a house now, but once the wife's car is paid off I plan to apply that money on a C5Z or possibly an LS3 C6 depending on what the market's like at that time.
