Ok, as a noob to modding, I come up with these questions from time to time that may sound stupid, but please bear with me.

My questions today are about buying second-hand tuners. Mainly, what role does the computer code written on the side of the car's control module play in getting a tuner. Will a tuner for one particular code not work with a car that has a different code? And if they do work from one code to another, what is needed, if anything, to prepare the tuner for use on your car? Is the code something that I would need to worry about or is it only taken into consideration when purchasing canned tunes from a shop like brenspeed or bamachips?

Any guidance in this area would be greatly appreciated.

Thanks.

tuners have this thing called VIN lock. wich means, that tuner is married to that car. in order use the second hand tuner the original owner must put his car back to stock and divorce it. but make sure its for your year of course. 05-07 i believe. did this help?

Yeah, that helped, I just had heard that when you go to order a tuner, they ask you for your computer code, wanted to make sure that if i grabbed a used tuner, it would work on my car with little difficulty.

As long as the original owner returned his vehicle to the stock tune, which was saved when he loaded the performance tune. This saving of the original tune is what is called a "Vin Lock", which marries the tuner to that car. Once the original tune has been reinstalled on the married vehicle, the tuner is now unlocked and can be used on any vehicle it was designed to tune. Make certain the unit you buy is for your vehicle, they are not interchangeable. I used the Predator, and am very happy with the results./ Bill
