I don't think the ECU swap will work. Sport mode has a lot of other little things that support it. If you want more storage than the F3-S has, you can fit the F3-S with most of the same type saddle bags, different seats, and trunk boxes. I just use nylon bags when I need them. The F3-S the way they come from the factory is more like the old sport bikes from Honda and Yamaha I used to ride long time ago. About the same seating position, low behind the tank, and stripped of any fairings, wind blocking or other comfort accessories. Same with all the Harley Spoerters I owned. No windshields or fairing at all. One of them I bought used had a nice windshield on it when I got it. Rode it for about a week and took the windshield off. I have never even put a windshield on my F3-S. No floor boards, or saddlebags. It is basically a stripped down model with the same engine, drive train, and horsepower as the touring bikes hundreds of pounds heavier. I got the large rear pulley from the factory. Still got just the tinted gauge spoiler which is nothing more than a low piece of plastic to keep bugs from splattering on the front side of the gauges. I think maybe the large rear pulley may be part of what makes more power at the rear wheel in sport mode. It lowers the gear ratio at the final drive belt, and trying to put a different ECU in a model not designed to run it would probably confuse all the systems so bad it would be a nightmare you don't want. I used to put the 1200 top ends on the old old 883 Harley Sportsters and run them with the 883 geared down final drive pulleys and belt, but that was long before any of the electronic control systems or having sensors everywhere. The old carbed Harley Sportsters had nothing electronic on them unless it was after-market and you could get away with swapping 1200 and 883 parts around. I don't think you can get away with anything like that on the Spyders with all the electronics on them. It is not always easy to keep them going when the electronics are on the model they belong on.
The sport mode is basically just a thumb button on the hand grip that lets you swap the fuel injection mode up to feed more fuel mixture in at a faster rate and you would have to have all the buttons and the fuel injection parts to make Sport Mode work on a model it was not OEM on. That along with any other factors affected would be a project not worth jumping on when you can get a 5 or 6 year old low mileage F3-S now that came stock with it.
My 2015 F3-S has most of those features you mentioned, such as the larger rear sprocket and lack of touring accessories.
The horsepower rating has also remained unchanged from 2014 until today.
I suspect the CKP and CMP sensors, TPS, as well as the temp, pressure sensors, and the fuel injectors are unchanged.
BRP wouldn't spend the money to change stuff and recertify the emissions systems without any increase of power or other benefits.
Some of those items, such as the final drive ratio, tach, and speedo calibrations, etc are adjustable in BUDS.
My DynoJet PV4 gives access to the fuel and ignition maps, fan on/off temperatures, throttle mapping, and many other functions, but unfortunately it doesn't include fields to adjust traction control or other nanny functions. It MAY actually have the capability to modify those parts of the programming, but these things are such low production machines that no-one out there has taken the initiative to reverse engineer it yet.
Your gauge console is visibly different from mine, and MAY use a different connector, or a different CAN protocol to communicate with the ECU, which would be a difficult hurdle to overcome.
Could you take pics of the controls on your handlebars, as I'm not sure when those switch layouts changed.
Thanks for your input. Maybe, with enough help, I'll eventually find a way around this problem.
