2018 Indian Chief, "Adeline"
Since I'd be changing the subject of the thread above, I decided to just start a new discussion.Man, I wish my 2021 Springfield DH came with it! I don't like using the phone for my GPS and prefer something fixed to the bike. I'd have loved to chug the Garmin in favour of something that was part of the bike!
Hope Indian offers it separately as an accessory for bigger bikes.

In the thread above, a lot of the discussion was how many of us wish we could retrofit the new 4" Ride Command on our older bikes, and how Indian wouldn't allow it so you'd be encouraged to buy the new bike. This thread isn't a discussion on whether someone should or shouldn't attempt a retrofit. Instead, because we know there's fitment (what Indian says works, or "is allowed") and fit (what works, but Indian would say doesn't or "won't allow")--for example, fitment claims the air shock from a chieftain cannot be installed on a chief, but there's countless threads of people doing just that, and loving it until they install an Arnott or some such--this thread is about identifying what would actually prevent it from being retrofitted to an older bike from a purely technical perspective (e.g. not considering cost).
@HINK , if you think General Discussion is the wrong place for this, could you move it for me? * you’re good. This covers a variety of models so “general discussion“ is a good place / Hink
My own thoughts so far...
The 4"RC device is probably tied to the ECU, so I'd wager this is probably really a question of whether you can retrofit a 2022 ECU onto an older TS111. Since I own a 2018 Chief, that'll be my example. So, what would tie an ECU to a specific model year of TS111 bike?
- Rear cylinder deactivation introduced in 2019 is a possibility. From what I've read on it in the forum (admitting that I may have missed some tidbit of vital info), it sounds like the deactivation is solely an ECU thing--that is, there's no mechanical disconnect happening there, just the ECU cutting the fuel to the rear cylinder. Please correct me if I'm wrong.
- Ride modes--I'm aware that some of the newer TS111's support multiple mappings from the dealer. Again, though, this would just be a software thing--install that ECU on an older bike, and now the older bike supports multiple ride modes.
- I'm sure that by now we've all seen or heard about the upcoming VVT. it seems that was not introduced for the 2022 model year 111's, but when it comes, that would absolutely tie an ECU to its model year, since there are mechanical differences to the bottom end of the engine to advance/retard the valves.
- Weights/balance of the pistons, crank etc -- There are threads on how these get adjusted as time goes by--the thread about installing late(r) model jugs on an older bottom was a great resource for this. My guess is that the ECU may compensate for this by adjusting timings and such, but I don't see where that would prove problematic retrofitting the newer ECU to an older engine that doesn't have weights and balances the ECU would expect. Or, nothing that couldn't be resolved with a custom tune, anyhow.
