ECU CCU TEST SWAP LIMP MODE HELP 06 M6

[ilovepowder]

MY BUDDY HAS AN 06 M6 AND IT SEEMS TO BE STUCK IN LIMP MODE. WE HAVE PUT ON A NEW SERVO MOTOR AS THE ONE THAT WAS ON IT WAS NO GOOD.
I WAS WONDERING ABOUT TESTING THE ECU AND CCU.
WHAT WOULD BE THE BEST WAY TO DO THAT. I HAVE AN 07 M8 THAT WORKS WELL AND ANOTHER FRIEND OF OURS HAS A CROSSFIRE 700 AND I BELIEVE ITS AN 05 OR 06.
CAN WE TAKE THE ECU AND OR CCU AND PUT IT ON THE OTHER SLEDS THAT WORK GOOD TO TEST IT?
OR WILL WE RISK BURNING SOMETHING UP ON THOSE SLEDS?
WHAT TESTS SHOULD WE DO AND WHAT READINGS SHOULD WE GET?
DOES ANYONE HAVE THE APV CABLE LENGTH FOR THIS SLED?
DOES ANYONE HAVE THE STATOR TEST READINGS FOR THIS SLED?
WHAT IS THE BEST WAY TO GO ABOUT THE ISSUE.

THE SLED IS IN LIMP MODE DIRECTLY AFTER STARTING IT.
ANY IDEAS WOULD BE HELPFULL.

Check the taillight wire, my m8 went into limp mode cause of a shorted taillight wire.

Just my .02

WILL DO THANKS FOR THIS IDEA. WHERE WAS YOURS SHORTED? WAS THE TAILLIGHT ALSO NOT WORKING?

ANY OTHER IDEAS WOULD BE HELPFULL, I THINK WE MAY WORK ON IT TOMORROW FOR A WHILE.

Checked taillight wire is good. Check pipe sensor it is good. .
Here is a video of it running.

Brought the sled to the dealer. Exhaust can was plugged. Sled has a speedwerx pipe and can on it and the can was falling apart inside causing to much back pressure for the sled to rev out.

Turns out it was a sno stuff can that was on the sled so it was no fault of speedwerx at all.
Typical, everything I have ever heard about sno stuff is that is junk and my first experience with there product and it is junk.
Now to decide what kind of can he wants to buy that wont fall apart. Anyone have a killer deal on a sweet can for a 06 m6?

Jeez that can really was falling apart inside. Glad you got it figured out!
