I have a 08 Electra Glide Classic I install the power commander III in Dec and today it died.This morning I started my bike ran great as always drive 6 miles to town and it started missing when i slowed down. When i got ready to come home it was hard to start and black smoke came out of the pipes like it was flooded and it missed all the way home. I took the lap top out to check the PC and it is no longer seen by the lap top are the desk top. Has any one had this problem.

 

Check your power and ground connections to the PCIII.
