So I bought a smarty ran the catcher for a couple of days. Everything ran good and I was fairly pleased with it . Exept that I wanted more power, so i downloaded the TNT. After changing the torque management and vgt it went to go through writing memory and then said turn key to off and press '>' so I did then it said turn key on and press '>' so I did. Then it said connecting please wait so I did then it kept doing this whole cycle. So I called Bob and he said to unpug the batteries for a 1/2 hr and it still goes through the same cycle? I have tried to unplug my air dog (incase it is drawing to much power), put my fluke meter on the batteriesand they are at 12.8, checked the fuses and looked at the obdII port wires and plug. I didn't change any mods and it was writing tunes just fine lastnight. I guess I will have to wait for Marco or maybe someone has had this same problem and can help me. Oh it also has the check engine light on after this ordeal it starts and runs good I just don't want to drive it.
