The short cable that went from the PCV to the AT-100 needs to be replaced with a 6' cable available from DJ. It plugs into the PV just next to the main PV connector that goes to the bike's J1850 data port under the left or right side cover. That connector fits in the rubber boot on the PV which appears to seal it off well from the elements. The AT-100 needs to be powered, so a splitter is available for that purpose. One end connects to the J1850 port and the other splits, one going to the PV thru the 6' cable and the other to the AT-100.
Not to panic anyone, but I've had trouble with this arrangement and DJ is working to figure out why. When the splitter is used the gauges blank sporadically and the PV will lock-up. Unplug the AT-100 and all is well again. The data port only provides power for the AT-100, so in theory if you attach 12V to pin 4 and ground to pin 2 the unit should work. After powering mine in this way it still doesn't work, so I obviously haven't delved into any datalogging with the AT-100 yet.

I haven't used my AT-100 yet with the power vision, so I will just wait until you get the bugs worked out.
thanks for posting. I already have the cables from Jamie but wanted to try with the stock O2 sensors until I got the hang of it. Sounds like it was the right thing to wait.

I have gone through 3 maps from Jamie, and am now modifying one that he sent. Timing hasn't been being pulled by the tuner even when I have 4deg knock retard in the front cylinder w/ 2-3 in the rear and the ping is lasting 6-8sec. I have been manually pulling the timing myself so that I don't further destroy my motor. Afterall, it already has over 6300mi on it and it has been pinging the whole time... and it is still a few days shy of 2mos old. So I can't afford to NOT pull the timing lol.

Problem: Jamie, I seem to have run into a problem with the backup up and restore factory calibration. The first backup went fine. I went to the dealer and had the EITMS download installed into the bike. I backed up this calibration and when I went to edit it's the first backup no matter what I do. I can't get to the second or third load (we tried twice at the dealer). The ECM copy of factory calibration is always the first file and not the EITMS load. I can see all three backups on the Power Vision but for whatever reason I can't get to the second and third loads. Is this a bug? It seems to me the software in the Power Vision should store in the copy of factory file the last backup I performed. If this is not a bug how do I get to the calibration I need?

BTW:
I just backed up each stock backup to my computer and restored them to the Power vision one at a time to see if I could get it that way. No, it still shows the original ECM load. We have a bug here somewhere.

It hasn't been established that there is anything inherently wrong with the AT-100/PV combo just yet, but rather it just doesn't work on my bike yet. There could be an issue with the bike or something unique to the year-model, so I wouldn't hesitate to experiment if the AT-100 and new cables are already installed. Let us know if it works. In my case the AT-100 hasn't been working for over three months, so maybe it has developed a problem. It worked in February when the PCV was pulled off the bike.
Also, has anyone been running the AT-100 with splitter and CAN cable to the PV with success? If so, please state year-model and any details you can.

My rig is as follows...2011 Dyna Super Glide Custom... PV with a newly purchased AT Pro kit...contains an AT module, CAN cable, two WB O2 sensors, and the splitter cable. Like I said, now that I have the bugs worked out, it seems to be working perfectly.
The only issues (beside the one stated) had to do with the instructions (or rather, the lack of instructions) with the AT kit... None are included, and the only written info that's included refers you to the PCV documentation on DJ's website... however, the AT module I have is different than what's shown on those directions... I have a single module with two sets of connections (one for each 02 sensor), whereas the website shows only a single set each on a pair of AT modules... But hooking it up still was easy enough. I only had to verify that the connections labeled "1" corresponded to the front cylinder.. nothing, anywhere, says that. Jamie cleared that up in an email.

band sensors seem to show up for tuning changes. Warm up lamda always seems to read 00.0. Most odd.
Have the day off Thur and will spend more time on this.

I just setup a version of the map from Fuel Moto to use with the AT wideband sensors. I plan to set everything up tomorrow and begin tuning. I started by doing 7 tuning runs with the stock O2 sensors to figure out the process.
To setup the map for wideband tuning, I have set all of the AFR values in the cruise range to 13.8, Disabled Accel Enrichment and Decel Enleanment, Disabled PE mode & EITMS. Is there anything else you guys are setting for wideband tuning?

I've never seen anyone ask this before...maybe I'm the only one that doesn't know the answer, but I'm going to ask anyway....
The values of the VE table represent the volume of air moved by the engine... measured as a percentage of the engine's displacement...right? So, without any type of forced-air induction system (turbo, supercharger, RAM-air, etc.), how can those values be above 100%?
I realize that the values can be manipulated manually! But, as we use the logtuner and our 02 sensors to tune our engine, we're actually calibrating the VE tables for our specific engine...so even if we started with a map that had a bunch of values above 100%, wouldn't all these values decrease to some number less than that? On my engine, there are areas of the VE tables, especially for the rear cylinder, where the values are over 100, and aren't changing much.
These are areas where data IS being gathered... I obviously wouldn't expect changes in areas of the table where no data hits are recorded. And, the displacement of my engine is listed correctly in the Engine Displacement table.
It's not that I think something's wrong...I'm just trying to puzzle out the whole process so I understand it better.
Thanks,
Art
