I went to start tuning my Silverado 6.2L with the 6L80 trans and when i downloaded the files it had a 3rd controller it said something about a ctsv in the description of the controller. When i was in the house i bought my 2 credits but when i connected it to my truck it wanted another credit for the extra controller. HPtuner websight said i only needed 2 credits for this truck. Did i do something wrong? I am obviously new at this. Did i waste a credit? It says its Brickable in red. See the pic.
