PCV and EITMS not compatible?

On my bike, it never stalled, but didn't work the same as before the PCV. It would stumble bad when giving it gas. I have over 8000 mile on my 08' and know how it was before the PCV and how it was after.
So, today I was able to test it with the new firmware update from Dynojet, the same one Jamie was sending others to try. I also set my idle AFR to 13.7 looking at my laptop with it running. (I have the auto tune, so you can see your live AFR) I don't know if you should set that or not, but I gave it a try. I just added a 7 and 3 in the 0 and 2 percent throttle settings at 1000 RPM. I noticed my AFR previously was at 15 or higher at idle, so I thought I should get that down.
Anyway, I rode it around after in 95 degree weather letting it idle and get hot and it worked flawless! Just like it did before the PCV. I don't know for sure if it was too lean at idle or the new firmware helped. I can just take off, or blip the throttle and it works great.
So I suggest to anyone having the problem is to update the firmware and see how it goes.

I would also like to add that for anyone considering the PCV, my bike rarely goes into EITMS mode with the PCV installed. Last year before the PCV, EITMS kicked in several times during my afternoon commute. It has been hotter this summer and the bike definitely runs cooler.

I bought my setup from Jamie mid june I think and got home to see this thread. Oh well... otherwise it performs flawlessly. I have over 10000 on my bike and know how it ran before, and how it runs now. Great power, much cooler, and BTW my gas mileage has gone up from ~40mpg to 46mpg.
The ONLY problem is when EITMS kicks in, and it did so on saturday for me in traffic. I went to accelerate from a stop and the bike just quit. It never did it before the PCV. So because I was aware of this from this thread and still stuck in traffic, I ohhh sooo gently gave it some throttle and then clutch and it pulls away fine. Only problem I see here is if I am sitting at a light EITMs is on and I have a cage coming up my ****... my instincts will just be to give her throttle and go and the bike will quit.
I will have to break out/borrow/steal a windows laptop to see my map and firmware version. But I am wondering... I don't have auto tune... but would adding a few % at idle maybe make the difference here??? Anyone else have any ideas? Why is this doing it when EITMs is kicking in... it does act just like a bike running at idle to lean. Wife's sporty acts exactly the same when idling and blipping the throttle when it's cold and the enrichener is not engaged, it even does the carb fart (vice throttle body backfire). Is the PCV somehow messing with the skip firing of cylinders and fuel delivery or something? I could tell EITMS was kicking in via the idle, but smelt nothing unusual.

Like I mentioned on another thread a while back, the only time my bike has hit EITMS is in my garage while watching the PC software readout, most recently about two weeks ago. I made a point to blip the throttle fairly hard in neutral, and it recovered to normal operation with hardly a hestitation.
I'd like to pose a question to those who've had hesitation problems, which is whether or not you are running aftermarket cams and AT. I've noticed that on my bike and others with a cam mod that if Target AFR's are applied to 1250 RPM @ 2-10% TP that AT will trim too lean in those cells. That has caused hesitation with my bike when not in EITMS, and I would imagine that it would definitely cause the bike to die if it was in EITMS mode. Without going into a long-winded fix at this time, which I can do if anyone needs it, I'd like to know how many have aftermarket cams and/or AT.
If you have AT, even with stock cams, check your base-map and trim values for the above range. If they add up to negative values more than about -25, this may be your problem. This means if you have -10 in the base map for a given cell, then -20 in the trim map for the same cell, you have a total change of -30, and that's 30% less fuel than the ECU is dictating.

I have a set of Wood's TW6-6 Cam's in my '09 with a PC-V/AT and was experiancing the hesitation IClick is mentioning. I took his recommendation (install 0's at 1250rpm between 2% and 10% TP) It took care of this problem. I'd like to add that according to Jamie, alot of the '09 bikes running after market cam's are running extremmely rich at idle (something to do with the MAP sensers) . What Jamie directed me to do was set the idle afr's in real time, in other words, let the bike warm up, hook up my laptop, watch the real time afr's and adjust the base map numbers at 750 and 1000rpm until it's reading as close to 14.0 as I could get it. I did both the above mentioned procedures and the bike run's awesome...............Rich

+1 Did the same here but on my 08 it took +3 and +4 to get to 14.0

I got caught in city traffic and it was very hard to get going when the light turned green. Then one time it just died as soon as I tried to go. I've turned off the heat management, but I wish there was another option.
