PCV Threw Bike into "Limp" Mode
I've been running a Power Commander V (PCV) on my '07 Fatboy for close to six very satisfying months. The bike has been running extremely well; there was no prior indication of trouble. Just before Christmas, coming home from work, I exited the highway and my bike went into "limp home" mode at the stop light.
The bike didn't throw any error codes which wasn't any help. Early on, I removed the PCV and reconnected the ECM factory-style and the bike ran fine again. I reloaded the map that I had been running, hoping it would thump the PCV back into working order, but no dice. Now I am running lean.
I hate to abandon the PCV for broke. Can you recommend any troubleshooting steps that I can put toward the PCV? Does DynoJet have a way to confirm that the unit is ruined beyond recovery?
If the tuner is toast, I am considering a dyno session with factory ECM tune. Are there any cons to this route other than cost?

Mine did the same thing just weeks after having it installed. I was against a piggy back fuel management system from the start but got talked into it by a local Indy. When it happened I removed it and the bike ran fine. I later went with the SERT and Dyno and haven't regretted it.

Have you contacted Dyno Jet about the Power Commander V or even Fuel Moto to see if they could help?
Might be a loose contact or something as simple as that. Check all the connectors for corrosion as the weather has been nasty and could be causing you the problem.

not to rag on, but I've read a bunch of times over the past 7 yrs about Pc's or piggybacks systems can do this..
Big reason I went with SERT 7 yrs ago. Though I know there are better FM's out there now...
