P0505-IAC Low / 1 trip

P0505-IAC High / 1 trip

P0374-Cylinder Sync Lost / 2 trips

Front & Rear BLM's have a few red cells and I tried Apply but they still are off.

I also notice that according to the TCFI Log, the volts are between 13 & 14 even at speed. I know a Twin Cam is supposed to put out 14 at idle and figured it would slightly increase at 2000rpm or better?

New battery, voltage regulator and fairly new stator...
What do you mean by "ET on the TCFI log to not even be on the chart"? Is it low or high? It's just not showing up? Is this in the Real-time view or the chart view?

I more or less resigned myself to having P0374/P0373 errors. After multiple discussions with Chris, it's my understanding that when this gets thrown at start-up it's usually due to low voltage. I checked and rechecked all my connections. Chris' suggestion had been to put a heavy duty battery in...and I would, except no one makes a heavy duty battery for the late model Sportster.

FWIW, I normally see between 13.6 and 14 volts while cruising.

Are you having idling problems? Or just the error codes indicating a problem with the IAC?
