PLEASE NOTE: DIYAutoTune did not ship these with mounting brackets, and has made no effort to manufacture or provide the brackets, therefore the ECU needs to be wedged into the stock bracket, or held in with zip-ties. This is unfortunate, and we recommend contacting DIYAT directly for any and all complaints as they’ve been unresponsive to us. Because of this issue, we have taken a personal hit and discounted these ECUs to you for the inconvenience.
