not what I was hoping to hear but thanks a lot for the clarification. best, niv

 

Steve,
I recently spoke with your colleague (Chris I believe) there at TTS; he was very helpful. I'm rebuilding the motor of my 2003 softail deuce and have been waiting for the 4-pin TTS units to come available (along with pipes from D&D). I understand they stared shipping recently. The thought crossed my mind after the conversation to replace / upgrade the ECM on my bike since it is 20+ years old. What suggestions could you offer to get the best tune possible (perhaps closed loop) /O2) for this bike? Ron at RC will be doing the build; Bob the tune.
Thanks,
Doug

 

Going back that far there is not much I can recommend in the way of an upgrade for the ECM. The 2001 - 2003 used an ECM that was only used in those years of production. In 2004 the ECM was changed and the wiring on the motorcycle was changed along with many other items. When we developed the add in O2 sensors we only tested it on 2004 and newer models. The 2001 - 2003 models were never tested and checked out to see what might be needed to add the O2 system to that model. One other thing is that HD announced that they were discontinuing all parts support for anything pre 2014. So when current inventory parts run out that's it. You having a 2003 are **** out of luck and the upgrade part for your ECM is also on the hit list now. So you may want to look at getting the replacement updated ECM while there is still a chance of getting one.

 

Thanks for the response Steve,
Understood. Considering I plan on keeping the bike, I wonder what my options are. Though moving to an updated closed loop system may not be a realistic option, I'd at least like to get a newer ECM and if necessary have it flashed at Harley and then have a TTS loaded and have the bike dyno tuned. Though non necessarily optimal, it's worked on this bike for me very well for the past 15+ years. With respect to pursuing said ECM, do you know of anyone or a savvy Harley dealership that my be able to steer me in the right direction? Ron at RC is probably a good start I would think.

I currently have a 2019 road glide tubed withe the green tts box. I used analog wide bands along with the factory O2 sensors for tuning. Can I do the same with the can bus bikes? What parts do I need to buy?

 

You can use that same green VCI, external widebands & on board narrowbands to gather data with DataMaster, and use VTune to sift through that data to modify the ECM mapping. You'll need a new 6 pin Bluetooth VCI to flash the ECM.
The Analog channel setup in DataMaster provides a list of compatable wide band controllers.

 

Ok thanks. I use the ballenger afr ntk 500's. They work well.

 

how or can you switch the ve table to kpa vs rpm instead of rpm vs tps?

 

I believe you can only do it on '14-'16 tbw touring and '16-'17 tbw softails and the '17 Dyna Lowrider. Bad memory but any canbuss twin cam tbw bikes.

 

There is no switching the VE tables, unless it was in the ECM to begin with. Some years are Map only, some are TPS only and the odd ball one was the 2014 - 2016 TC that would allow you to select which one you wanted to use.
