Hi,

I have a spare ecm for my lbz that i have a dsp5 program on. It started running bad this morning and I swapped the stock ecm back in and it ran fine. After work i was going to reflash the dsp5 tun file back in and I get the following errors

EFI live detected the ecm may not have valid calibration

flashscan is not able to determine the liscense status of the ecm

then it says the ecm is in an unknown state and disconnects.

Any ideas??

Thanks

I let it sit for about a half hour and restarted my laptop and it did a full reflash. Not sure what happened

Weird Things like this happen every now and then. I just plugged my scan tool in one time and then the truck would not idle for the next 2 hours. :( but it recovered on its own. That was a gasser tho. Strange things happen when you use computers
