will running 17" snows on my 07 Aspen mess up the PCM?
I want to make sure that it won't make the traction control dangerous to use or royally mess the PCM. This is obvioulsy not a +1/+2 -1/-2 situation as mine is calibrated for the 20" wheels. I estimate (depending on the tire) about a 5-7% error on the speedo which I can live with to run an aggressive snow tire for a few months.
I would prefer not to have to find someone with a decent scan tool to recalibrate the speedo but just wanted to check in with a few people in the know as to whether or not this is a slippery slope with this PCM. It appears as though it monitors pretty much everything especially with the EVIC. Thank you, A. |
I run 17's in the winter
I used the same size as my spare all around so I don't think I have any issues, saved my 20's for spring!
