I did a lightning swap on my 02 gt. I tried hooking up my SCT X4 to the car and i keep getting error 11020. Battery voltage is at 12.5v and i tried it with a battery charger on and off and it made no difference. I just got my sct x4 back from sct after getting it unmarried. I tried it on another vehicle and it reads that vehicle fine. Weird part is it will read and clear codes from my car it just wont let me read vehicle info or let me in to tune. Called sct and been working with them with no results so far. Any have any ideas on what to try to get this thing going?
