New Auto Tune modules, No Trim values after a 35 mile ride on warmed up bike.

Bike = 2009 Street Glide, PC-V, 255 Cams & SE Heavy Breather (Base Map from FM). I bought a set of new Auto tune modules back in November, just installed them today and spoke to Keith, from FM, about 3 times during the install for little info here & there.

I upgraded the Power Commander Software to the latest Version 1.0.3.2 and also the firmware to 1.4.0. Had a little problem with the firmware, but re-upgraded several times till it took and gave me engine temp reading. Did this while on the phone with Keith. At that time also enabled the Auto Tune feature & hardware switch. When connected to the PC-V in the garage with the bike running, I do have good AFR values reporting back to me on the gauge section of the software (right side of computer screen).

While I was at it, I installed a MAP switch connected to pins #1 & #2 (per Keith pins #1 & #1 are closest to the center of the PC-V where the wire harness enters the PC-V). I used the unused Assy switch on my Street Glide dash. Before I connected it I checked the wires with a Fluke meter for voltage in both the ON & Off positions - I did not have any volatge. I did have continuityof 0.1 ohms when in the On position and no continuity in the off position.

I went for a 35 mile ride and came back to accept the Trims, but the were NO trims! Anyone know why? I did enable the Auto Tune and the Hardware switch.

I am leaving in the morning on a 1500-2000 mile ride and wanted the Auto Tune to do it's magic while on the trip (I'm bringing my laptop with me).

P.S. On the 35 mile ride I did not turn the MAP switch on, I left it in the open position.

 

The AT is not as easy to install as the PC..chances are you missed a step. Make sure you plug into the diag port on the clutch side. If you read the thread below there are many of us that made mistakes with the AT install. I have done 2 of them now and really like the AT...

I also recommend, make sure you have AT1 connected to Cylinder 1.. although that won't give you no trims...it will try to make cyl 1 act as 2 and 2 act as 1... if you got your map from FM, you should not see +- 20 values in the trim tables... another thing that I did was to only let the AT adjust my map by 5%. If you have a good base map...5% adjusts will be fine.

When you start the bike, it takes the sensors a few minutes to warm up then you should start to see you trim values changing..

re-check the instructions..you may have missed a step or did something wrong...

luc.who,
Thanks, I checked out the thread and have tripple check my install (I used to work as a mechanic, so wrenching is not new to me). I see where others had issues by plugging into the wrong Deutches connector, but that is not my issue. I am in the correct connector, PC-V is working fine with it's base map, my AFR's are changing normally. I just can't get the AT to show me suggested trim values.

I double checked that I have AT1 connected to cylinder #1 (Front) and AT2 connected to cylinder #2 (Rear). Tripple checked the wire color code from the O2 sensors to the AT modules.

Does it matter what order you connect the CAN plugs between the AT modules and then on to the PC-V? Or what port on the AT modules the plastic terminating connector plugs in to? I currently have AT #1 plugged in to AT #2 with short CAN cable, Termination plug in second port on AT #1 and finally from AT#2 connected to the PC-V with the long CAN cable.

 

A quick check to see if your O2 sensors are working properly is plug in to the laptop while the bike is running in the garage. Make sure you have AFR1 and AFR2 setup in the gauges on the right side of the screen in the PCV software. If the AFR's read 0.00 after a few seconds once you start the bike then you have something messed up on the installation.

If that's the case make sure you are plugged into the diagnostic port under the left side cover, not the one under the seat. Also, gently tug on your connections to the AT modules and make sure they are seated.

If you are showing values in the AFR gauges...then I would disconnect the map switch, go for a ride, and see if you come back with any trim values. I suspect you could have something wrong with the map switch or connection causing it to disable auto-tune.

 

AFR's are good when in the garage. I am going to disconnect the MAP switch and ride it to see if I get any trim values. Thanks for all the suggestions so far - I'm open to more.

I am leaving early in the morning on my Eastern Seaboard ride. I will check this thread when I stop to eat or for the night. I am hoping I can get this Auto Tune working properly while on the ride.

 

P.S. I used the unused Assy switch on my Street Glide dash. Before I connected it I checked the wires with a Fluke meter for voltage in both the ON & Off positions - I did not have any volatge. I did have continuity of 0.1 ohms when in the On position and no continuity in the off position.

 

If you are getting updated AFRs while monitoring the PC, then it does seem that it is connected correctly...

I haven't connected a switch in either configuration i have had... So I too would try what you are doing, disconnect the switch and see if you get any values in the trim tables.

The other thing, that I would try is going back into the PC and toggling the AT enabled button...if its enabled..disable and back on...

And then of course Keith and Jamie are options..

 

I had the same problem this is what Jamie wrote:

The CAN termination plug is not installed in the Auto Tune module, you need to remove the rubber dust cover and plug in the plastic CAN termination plug. Also make sure you have the Auto Tune module plugged in to the data port under the RH side cover.


I hope this helps

 

While installing AT on my 09 FLHR I found the instructions detailed but easy to follow. For me it was hook it up and ride. Within 2 minutes the AT made the adjustments and the bike has run great ever since. The PCV with AT is a great product for the throttle by wire bikes.

 

That may be the problem, as in this position it is running in open-loop and the base map. It may not be writing trims in that position, although I'm not sure about that. Try switching to open contacts (normally on) and see if values start appearing in your trim tables.

I hope you checked for voltage when the ignition was on. If you connected to the ACC switch harness under the seat without removing the P&A fuse you may be feeding 12V into the PCV.

Double check that terminator plug, as that's what caused me to have the same symptoms at first. This is not the rubber plug that was in the unit originally.
