help with SCT tuner
just bought a second hand tuner which was unlocked/unmarried (actually, it was never plugged in to a vehicle)... i attached or 'married' to my VIN and downloaded the custom(only thing in it was supposed to be CAIK, which i have) 87 octane tune with no problem, and didn't change any of the adjustable parameters.
i have 2 questions, if any of you can help:
1. i wanted to try the strategy(i'm assuming these are the 'canned' tunes) tune, as opposed to the 87 octane custom tune on unit which was the one i downloaded. i was not able to do it... got error unable to unlock ecm(or ecu). do i have to return to stock BEFORE going to the strategy tune???
2. i understand the device can only be unlocked 5 times... every time you switch back to 'stock tune', are you actually "unlocking". i was hoping you could switch back to stock as often as you wanted, and hoping that "unlocking" the unit was only a manual procedure to detach or "unmarry" the car from the device???
