Auto tuner Help

i know that there are many threads in regards to this. But really haven't found one that can help me identify my issue. I have the PCV w/Autotuner installed. I have read someone elses thread where they explained the settings to go with in the AFR for starters. But once i go for a ride, i come back and except the trims, bike is riding rough. like it isn't getting enough fuel. when i reconnect the computer, i go into the trims and it keeps telling me that they are all 0. I have reset the map to allow the bike to run better, but haven't been able to identify why the autouner keeps setting trim at 0. i have looked over installation, and everything (to my understanding) is setup properly. the one thing that I have notice, is that the autotuner light hasn't came on when i have the seat off. is that because it has to be set at a certain temperature or RPM's for it to start? anyways if you all have any information that can help, i would really appreciate it.

When you accept the trims & SEND MAP ~ you are telling updating the PCV with the new map. The trims should be zero till you ride again. In theory the more you ride and accept trims & SEND MAP ~ you are lowering the amount of trim necessary to stay within the afr range. Hope this helps ~ I have had three bikes and 200k on the autotune ~ this is the best explanation I can provide ~ SemperFi

Are you talking about PC-V or PV? I'm confused. I have had both and your description sounds like PV.

Michdm, so do i continue to ride the bike the way it is after i accept the new trim. even though it is running like crap. backfiring and almost stalling. and continue to accept the trim tables. not sure i understand what all i should do. the bike was running really bad. was scared that I would damage something. again, thanks for the help. still messing with it.

The PC V uses autotune in real time. I'm not sure what your talking about when you say you 'accept' the map changes. The PC V ('09 Fat Bob) I had used a set map as designed for the equipment I had on the bike and the autotune monitored the added wide band O2 sensors and made changes in real time.

Maybe they have changed this setup.

If your autotune light isn't on then for some reason the autotune isn't working. That would explain why it isn't setting trims. The PC V either is set for a time delay, or a temperature setting before autotune is activated.

If you are not sending map then accepting the trims is not updating the PCV ~ so here is the short of it ~ if the bike is runnin like crap check all 12 wires off of the autotune module ~ Unplug the Module completely load a generic map from FuelMoto or powercommander.com to see if this resolves the issue. Either one of the wires has come out of the autotunemodule, or you could even have an 02 sensor failure ~ this would require doing the recommended 02 sensor test by powercommander. I have had a wire come out of my autotune module, and have had an 02 sensor go bad on a previous bike ~ the quickest way to trouble shoot is to install a Known good map to the PCV with the autotuned unplugged ~ if it is getting a bad reading from an 02 sensor or a wire is not seated correctly ~ it will corrupt the map in the PCV.

How I know this a buddy of mine had a similar incident to Dbell with something hitting the crossmember of the frame below the oil bag. My Buddy's cracked ~ runs bike on no oil ~ the autotune did it's best to compensate for the rise in temps and other issues associated with no oil. Progressive bought him a 13 ultra limited to replace the 10. He kept his PCV & At ~

On the 13 the dealer installed 555's from FM before delivery but could not get the bike to run with the PCV and autotune. I went by the dealer and downloaded a known good map to the PCV and all was well ~ the autotune will compensate for the rest of the tune as he rides.

I have had quite a bit of experience with the power commanders and autotunes ~ this by no means makes me an expert but I am a bit more knowledgeable than I was 200k ago ~ the largest error is accepting the trims and not Sending Map (this came from PowerCommander tech support) I was baffled why my trims were not getting lower as I rode until I had this conversation with Power commander.

Auto tuner

well the bike was riding great throughout the day. when I came home tonight, I accepted the trims and sent map. took the bike for a quick ride and at first was riding really smooth. about half a mile down the road, it started acting up again. turned around and resent old map. took it out and bike continued to ride like crap. not sure what is wrong, but it is late and my exhaust is to extremely loud. I like my neighbors, so will continue to figure it out tomorrow. will check o2 sensors and will disconnect the AT and take it for a ride. this is really frustrating, and hopefully will get this taken care of so I can enjoy the ride. thank you all for all the help, will call those that have sent me their number in case I hit yet another road block.

Well finally called Power Commander and the representative was able to assist me in figuring out the issue. I had the #1 and #2 o2 sensors on the wrong cylinder. went over my map and made small adjustments. have excepted the new trim and bike is riding very smooth. thanks all for the help.
