PCV and EITMS not compatible?

As Steve noted above heat management works in what Harley calls "phases" making changes to the AFR, igntion timing and ultimately controlling cylinder firing. Simply put you cannot Auto Tune under these conditions which is why you will note in all of our Auto Tune AFR tables that there are no values in this area meaning the AT will not trim, and it is very important that you do not alter the AFR tables to trim in these areas as it may cause an issue for reasons stated above.
The problem was that the software then recognized both the new base value and the trims, which not only would not change to zero on their own but wouldn't allow me to change them. Thus it was adding/subtracting the base value and the trim value causing bad running, which took me a while to figure out. I wrote up this "glitch" (my choice of words) here. It isn't a big deal and can be worked around, but PCV Auto-Tuners out there need to know about this "feature."

i have the same problem as th op. i just installed pc-v from fuel moto mapped for my monster ovals and se/ac. the eitms worked flawlessly before the instal and now the bike dies when giving throttle while coming off eitms. and yes i have tried blipping the throttle before releasing the clutch.
the good thing is it takes much longer for the eitms to kick in with the mods so the bike is running cooler. unfortunatelly i have had to turn if off until a solution is found as i like to be able to accelarate away from a stop without having to restart the bike

Did your bike get the HD Stage 1 download before adding the PCV? If so, is your map configured for Stage 1? If it is you should see mention of it in the notes section of the PC software (bottom center of main window). If not, call Fuel Moto and ask about it. If it says "Stage 1 AC" it doesn't mean it is configured for the Stage 1 download.
It could also be possible that AFV's (adaptive fuel values) are out of whack if you installed the AC and mufflers and ran the bike before installing the PCV. If you did this, call FM for help on getting it set right.
I don't have much experience with EITMS but have heard that it won't switch the rear cylinder back on 'til RPM's hit 1250. If you let out the clutch while below 1250 rpm's you may be still in EITMS while you're loading the engine, and with only one cylinder running it will kill much easier. Try giving the bike more gas before engaging the clutch, making sure it hits 1250 or more.

"you can't blip" lol well i could before the pc-v so what changed? and ya blip is a term, i can gently roll the throttle on when in neutral with eitms engaged and the bike will stall.....
Mine only stalled when I blipped the throttle. If I slowly rolled onto the throttle I was fine. I did have to change the values in the first column that were 3's to 5's to reduce the frequency that EITMS kicked in. But even when it does now, a slow roll gets things back to normal.

Same problem here. Died on me with a puff of black smoke trying to take off from a stop light while in EITMS. I've disabled it for now, and will try reviewing the map re: iclick's suggestions later. FWIW, I'm not running auto tune (yet).

I wouldn't buy Auto-Tune to correct this problem because it probably won't. The latest news is that keeping the bike in the base map (i.e. no AT) just above idle is best, so AT wouldn't help for the EITMS stumble. Mine has hit EITMS twice so far in probably nine months, once in the garage while fooling around with the PC software and another on the road in traffic. I didn't notice any stumbling either time.
