The way I understand how it works is at 100% TP and at a certain rpm PE is active.
I was never aware such a thing even existed in these ecm's. I have been to HD Race Tuner School @ HD in Milwaukee and such a thing was never mentioned. I think it is a neat thing to have though.
I own a 2011 Electra Glide and have 103", Wood 408-6 cams, high comp forged pistons, MVA heads, Hi-Flow a/c, FullSac B header w/ both bung sizes, SE street legal muffs (the ones that look like SuperTrapps. The only item I am happy with is I use 2270 in PV for my speedo and now it reads the same as my GPS but don't know how close the odometer is to being accurate
Talk about trying to tune this combination is exhausting sometimes. I have a copy of SESRT and have copied VE and Timing tables from that into various PV maps and some run good and some not. If you look at Harleys timing tables you will think you know nothing at all about how an engine should be timed. Sometimes I miss a set of points, a centifigal advance plate, and 2 carbs. LOL
The noise everyone hears @ 2200-2800 rpm's I have heard on all Harley engines stock or modified, Evo or Twin cam since I got into Harley's in '91.
New bikes out of the crate have it in various amounts and that always made me feel better that my bike wasn't broken. Usually it would diminish by increasing/decreasing the throttle a bit. It is always the loudest @ a steady cruise.
Getting back to the 2011 bikes they seem to have a new and unique operating system compared to the previous FBW years. I wonder how to set the throttle transition gear to 6th to only use the Alternate Throttle Blade Control table. This is a wierd thing as I have monitored the TP and the twistgrip positions and have seen the TP @ a higher number than the grip.
A long post but only a few of my wondering's of how things work and how can I change them. I want a week with the engineer that made up these fuel injection systems. LOL I want to play 2000 questions with him.

A question for iclick or anybody that can answer. At one point in time I had a calibration in my 07 that shut down the rear cylinder when the heads reached a certain temperature. 34412-07D is not it. 34412-07D is a skip fire calibration, It sounds very different than the one I had that shut off the rear cylinder. Actually I don't like this calibration because it really bangs hard on the transmission when it is active. The one that drops the rear cylinder does not do this. Do you have any idea what that EITMS calibration may have been?
I thought there was only one EITMS cal, which is 34412-07D, and when I had it installed I didn't have any banging like you're describing. I had 32903-07 (the "torque-smoothing" cal) originally, then 34412-07D, and I'm now on 32903-07E. The last cal didn't fix the idle issues, but changing the IAC motor did.

Anyhow moving on to power enrichment...
With SE 255 cams what RPM should I kick in PE AFR? I'm thinking 3200 RPMs, just outside of my cruise range. Does throttle position trigger PE mode or is it vacuum? Acceleration enrichment, what should I target for those quick throttle blips? I'm thinking 13.9 but I really have no idea.

My understanding is that it is based on duration (seconds) and RPM, not KPA or TP. I could be wrong, as I'm still trying to get a grip on some of this ECM stuff. I was a PCV guy for too long and my brain needs to be re-programmed. I'm having the most trouble figuring out the relationship between the AFR table and the VE tables, and I'm not there yet.
Accel Enrichment: I originally tried it at a leaner setting, but now have it back to stock trying to chase-down a very random misfiring problem that dates back to my PCV days. Are you having any issues using the stock settings?

FWIW for you '07 owners, 2135 gets my speedo correct with the GPS, but the odometer reads 1.2% low now. It was 2058 originally. BTW, the odometer and speedometer parameters in the ECM (readable with the PV) are not the same as the fairing gauges.

I left mine stock, at 5500 enable, 5300 disable. Why would you want it lower? I also changed all the values to 13.0, as they were all over the place and seemed irrational, going from 12.5 to 12.0, then back again, and as low as 11.5. I think this is to enrichen the fuel for people who run their bikes WOT for more than a few seconds, ostensibly to keep the engine from frying by throwing in some additional fuel every few seconds. I don't do that, so I'd rather the ECM not make such changes and keep it at 13.0.

I upgraded to the EITMS cal (34412-07D) a couple of years ago, and it shut-down the rear cylinder at 290°. Chasing an idle problem a year or so later I tried the newest cal at the time (32903-07E), and that disabled EITMS entirely. I haven't bothered to go back to the EITMS cal, as it only rarely engaged on my bike anyway.
I thought there was only one EITMS cal, which is 34412-07D, and when I had it installed I didn't have any banging like you're describing. I had 32903-07 (the "torque-smoothing" cal) originally, then 34412-07D, and I'm now on 32903-07E. The last cal didn't fix the idle issues, but changing the IAC motor did.

Question about PV and O2 sensors.
Back ground info:
I've been running the PC-V with AT for over 2 years now. I'll be paying Jamie a visit in July to get the 107" installed. Since he will be tuning it, I've decided to swap over to the PV. I removed the PC today, left the AT and WB O2 sensors in place, and then loaded the map Jamie loaded on the PV.
My Question:
Does the PV use the O2 sensors? Since I left my AT on but not connected, will this cause a problem?
I tried searching and couldn't find the answers and 67 pages are a lot to read through. Appreciate any input.
