PCv no communication with laptop

[Jon]

Got bike mapped right and everything set up...sounded
Great!! Went into shop next morning and started it up
Ran about min. Then died. Started it back up and it belched and
Died... Then got it started and sounded like it was running on
3 cylinders. Thought a plug fouled so I changed em and same
Tune. Checked PC5 and can't get any communication,no readings when i could get it running?? Any way to reset the
PC ?? It's running like a pirate w/peg leg..wondered anybody
Had any ideas??
The power lights flash back n forth on the PC but something is
Wrong some where...I plugged it back up stock and it runs fine!!

check the ground, it really needs to be grounded to the motor.

Got more issues now.. I checked all my wiring from the harness
To pc and ground( it's lock washer/bolted to frame) still ran like a
Harley so I disconected everything and started
It and ran better but still not right..so I took it for a short ride
At light pulled in clutch and Launch master held the RPMs and I
Took off!! Sounded bad about half-way then cleared up.
So I headed back thinking maybe some dirt in an injector.
Got back to light and stopped. Hit the throttle to launch and it
Reved way past MSD settings 6500rpm I though well it's not working
Now, but bikes running perfect!?!
Got bac in the shop and pulled seat...MSD wasn't powered on
No red light? So now I'm wondering what could be the issue??
