Okay so picked up another dsm yesturday and drove it home perfectly fine. Got it home shut it off let it sit for awhile then went to start it again and it started but ran really funny. And so im trying to get link back on the laptop and its saying that it cant connect. I looked it up on ecmtuning and tried mostly everything amd it still will not connect. I know if you unhook the battery then the tune will come off the ecu with v2. So my question is what else can i do to try to get the ecu connect to the computer
