Why are there 2 autotune units on my bike?
Why are there 2 autotune units on my bike?
What's going on, recently picked up a new to me used 2009 road king. Love this rig more and more every day. Right off the bat shes already got a set of full true dual rineharts and an arlen ness air cleaner under the stock cover and was curious about the tuner situation since I got it. Well today I did a little clean up on her, pulled the bags and seat and. Noticed a little wiring that piqued my interest which led me under the side cover where to my joy I find that I do have a tuner, a pcv....and even better it has the auto tune...
Which brings me to the source of the question.....there are two auto tune units as well as the pcv box all together there under my side cover. Why would there be 2 auto tune boxes? At quick glance they both look wired and plugged into places and they both look identical...
Ummmm what? Any ideas? Now I need to get a cable and hook into it all and verify function I guess.
Thanks

The first autotune modules were only single channel Or one sensor per module. They have a two channel module that replaced using two singles on the v twins. Just picked up a used double module setup and they are bad but when I first contacted dynojet that was my first question, why two modules. They said it was old, they haven’t made that setup in 10 years is what I was told. I’m paying them $25 to test them <was a wrench for 20+ years I know they are bad> in hopes they will give me a break on just the new dual channel module as I already bought two new sensors during my diagnosis. Curious to know if yours still works.
