They didn't commit odometer fraud, you did by not reporting the car to the department of motor vehicles as TMU.
You need a tuner, no dealer will risk it deleting it since it is absolutely illegal. It's a federal crime to remove any emissions control devices on a street driven car.
Avoid Ebay tuners, especially from a low feedback seller. Just spend the cash and buy one new from a reputable dealer so that it will work. Ebay tuners tend to be locked and unusable.
