    Default No Flash!

    The ECM is locked up some how and wont let me load in a new tune. Now it has corruted the tune that was in it to the point that it wont let me start the truck! What can I do to get this fixed so I can get the truck back running to take my kids home tomorrow?

    I just forced it by continueing to be more persistant than the ECM! So far it works perfect and loads up any calibration I am thowing at it now!

    I ended up loading the same tune that was in it from the beginning and then recalibrating it to the tune that I wanted in it. I was running a big tune in my truck, and wanted to drop about 50- 90HP. It just stopped in the middle and wouldnt reflash. Dont know what happened, but it is now good to go.
