I did a CAI upgrade (from VMP tuning) about a year ago, and kept my SCT tuner in my car. Unfortunately, the tuner broke. I just installed 4.10 gears and wanted to correct the speedo, so I ordered another SCT tuner. Will I be able to go in and fix the speedo without another custom tune for the CAI?
Unfortunately, I don't think you'll be able to. The way to adjust those options is just before you load the tune on; there is no way (AFAIK) to adjust them without loading the tune immediately thereafter.
call sct or vmp and get a solution from them. you do not want to hook up your new tuner with a non-stock tune already loaded in. it would be a good way to have to buy a new ecu. i would see if there was a way to send your old tuner to sct and find out if they can fix it.
