PCV/AT problem
I was wondering if anyone had had a similiar problem. My 09 FLHRC has the PCV with the Auto tune and it has stopped giving any trim values. I've checked all the connections but can't find any problems. It just stopped working at around the same time my bike started throwing codes for 'throttle position sensor correlation' I've had the twist sensor replaced but the AT is still not showing any trim values.
Any idea's?

I guess the proper term would be enable. Plug the PCV into the computer and make sure that the AT is active. My guess is it was turned off somehow when the codes were cleared after the throttle issues was resolved. Just a thought.

Have checked the PCV/computer interface and everything seems to be ok
I still cannot get the AutoTune to show any trims. I'm starting to think the AT has failed altogether and may need replacing.

Out of curiosity, have you checked to make sure the auto tune wasn't disconnected somehow or maybe one of the o2 sensor wires become unplugged? I had a bitch of a time getting the sensor leads to stay tight in the module.

First thing I checked
Today I unplugged everything and then used some dielectric grease. Changed the AFR and will see what happens tomorrow.

Called the customer service today
They talked me through the issue. Seems that because of the throttle twist sensor failure, the voltage sensor for the AutoTune was askew and not getting any readings for throttle changes. They were very helpful. All is good in the universe again.
