Power Commander User Guide and Install info

All connections appear fine, the red LED is alight (with an occasional flicker which I assume shows it's active), so I think my next move might be to whip out the wideband lambda sensor and see whether it coked up. Any suggestions on how to clean it will be greatly appreciated.

No idea about cleaning the sensor. I've heard that they're delicate and easy to bugger up. I would also suggest you have the PC-V software active and connected while the bike is running. Check the 'Autotune' active indicator in the lower right to confirm that the PC-V is actually receiving data from the Autotune.

I couldn't find the AutoTune indicator, so I updated the PC-V software. I was running the version that came with my PC-V. Alas, the AutoTune indicator is not illuminated. Looks like I might have a shagged AutoTune.

I'll double check the connectors, especially to the lambda sensor, and if all look in order, I will remove the sensor until I can get a replacement AutoTune. The bike is running great with my "zero" map installed, I can always revert to any of my saved maps, or if I'm brave enough start tweaking the PC-V directly should I feel something is not quite right.

Thanks again for your help.

No problem. I agree, check the CAN bus wiring between the Autotune and the PC-V and the wiring from the sensor to the Autotune. Plus check you have a good +12V and GND to the Autotune.

That's exactly what I done. At the same time, I shortened the cable from the lambda sensor to the AutoTune, and checked all other connectors. Plus, I found a use for the cut yellow wire that was once feeding the starter relay -it's now powering the AutoTune. And, hey presto, the AutoTune indicator is now illuminating after the 60 second preset delay. Also, I see a change in trim value being produced on a couple of cells.

I need to go for another test ride, but weather forecast not looking that wonderful. What I still can't understand is how the AutoTune managed to produce unhealthy results in the first place. I'm contemplating turning off the AutoTune except for planned excursions, so that I keep a good stable map on the PC-V.

Only speculating, but I would expect freaky data can be produced with a bad/intermittent supply or ground due to transient noise created by the connect/disconnect of the 12V or GND. Although, the CAN bus is supposed to work in noisy environments like this without issue. Hmmm.

Kiwi_dave,

I can see you've checked the connections but this may be worth something: I had intermittent operation of the AutoTune when it would simply stop working just like you describe, and in my case it was the connector that plugs in from AutoTune into the PCV. It is supposed to click in but really did not and had to be in really tight to be working stable. I bent the tab so it would lock better but in addition to that zip-tied it tight to the AT unit and had no outage since. Could be worth a shot...

As far as updating the software: good to have the latest version of the desktop but be sure not to upgrade the firmware in the PCV, even though there are several newer versions on the Dynojet website and the temptation is there...

AutoTune gets completely bogus readings in certain areas, especially really small throttle openings under load; as such it can only be relied upon to build a map from scratch if you know which cells you can trust and which to leave the AT correction off... This also means there will still be areas on the grid where we'll still have no idea how to correct for optimal mixture without dyno work and appropriate experience. This is something that I personally did not fully understand when I made my purchase; was naively hoping for higher degree of plain plug'n'play experience

This said, you could ask instructions from Todd to go from the baseline he provided to you originally to arrive to an even closer match. Essentially you'd be simulating a dyno run and pulling the map for him to modify for several iterations... In other words, still no replacement for a proper dyno run.

So here’s my question ? You get map, Accept trims then send map. Well I’ve got map but the how do you accept the trims, is there an option to select or just viewing then sending map is all that is required.

Do NOT Accept Trims, please just send me the map via email to have a look and tweak for you. I have this clearly stated as well in the Notes section of the map.
