Tire Size Reprogramming
Hey,
Recently my dad has stepped his C5 upto larger wheels and tires. I was wondering if we had to have the PCM reprogrammed for the new tire sizes to work with AH&TC.
I have heard that if this is not done, the two systems may have problems down the road...
Please advise on what you have done, and what I can do ... I do not mind buying the HyperTech to reprogramm for the tires, but if it is something that can be done for less ... I would not mind suggestions ...
Thanks :cool:

Re: Tire Size Reprogramming (AP)
You only need to reprogram if the overall diameter of the tires is waaaayyyy off. You can have up to 9mph different in front to rear (as seen by the computer) before it would know the difference.
Measure the overall, and if it is close, you will be fine.
