Once married, you can't use it to tune any other ECU, unless you "unmarry" from the original ECU. Unmarrying consists of reflashing back to stock, and then being free from the pairing. The AP is then free to be used on ANY other ECU, after being married to that new ECU.

I do know how they work, many of my friends with WRXs and STIs swear by them. But what I said was not untrue, you take away the access port, you take away the tune, effectively making it good for only that one car
