I have absolutely no interest in auto rev matching downshifts on my 9T but I am subbing to this thread after reading your write up alone!
All the best on the project.

Thanks! I know this is sort of a novelty and the 9T is pretty easy to rev match as long as you aren't trying to manually do it in the last 20m before an intersection hahahahaha.I have absolutely no interest in auto rev matching downshifts on my 9T but I am subbing to this thread after reading your write up alone!

Oh PLEASE don’t think I’m against any of what your up to …… the opposite my friend, I’m in AWE ! I love watching the deductive mind of man create machines with an understanding of the most minute deficiency in the process of getting horsepower to the ground and then developing unique computer controlled systems to make that transfer more efficient. It’s fascinating. I’m mesmerized and smiling not disappointed in the least. My thoughts move towards wondering what it will be like in another hundred years and celebrate my good fortune at being here at all to witness the advancements I have. Hell, ..I think simple fuel injection is a miracle. I salute you Sir. You take on a task worthy of your intelligence merely for the challenge and joy and not with capital gain as your motivation. There is honor in your effort to excel, you take pleasure in the accomplishment of bringing your thought into reality. That’s the heart of a creative mind …which in my world is a much greater reward. Can you imagine what this planet would be like if everyone had your curiosity and intelligence. What a world that would be. Tally-Ho deadwood ! I wish I had something to contribute towards your effort besides my applause and respect….. StayUpOn2 Sir ………..Blitz 🫡❤Data dump time!

Looks like the angular rate sensor (IMU) speaks in CAN. It just so happens this board has a whole section dedicated to CAN..... Now coding for CAN.... hmmmmmmmmm. Maybe not.

@BlitzSchnell I will be the devil's advocate. It is still just man and machine. The only difference is the amount of customization available. Some things are definitely hidden behind proprietary parts and protocols, but that allows mere mortals like us to use them instead of being relegated to racing teams where a corporate overseer dictates who can look under what cowling. It's the difference between riding a horse you have trained versus just riding a horse. Plus, I have decided this whole thing will have a kill switch, which is the clutch lever. Use clutch and receive 0 assistance.
Wow, the game is a-foot, the chase is on and the thrill continues to build. Seems the logical course would be to go straight to the source, the CanBus. Primarily because the focus would be on mental logic and firmware adjustments rather than the physical assembly of a pretty complicated wiring harness when the connections already exists. You’re going to have to tap the thoughts of the original engineers and get into their head….Looks like Mouser is going to get more of my money.
The CPS (crankshaft position sensor) is pretty easy to access, so it would be a good spot for an easily reversible harness.

And that connector is.......
What looks like a TE-Connectivity AMP MCON 1.2 LL 3-pin.... again. -_-

Onnly, there are two entries for crankshaft sensor test procedure. One of them shows the square wave I displayed before. The other shows an inductive sensor wave displaying a 2-tooth gap for TDC. The test plans also show a measurement on one pin and a measurement on two pins. But the wiring diagram shows three connections and there is an alternate crank sensor with two pins and body ground.

This all begs the question..... do I just bite the bullet and tap into CANBUS to get the data? The DWA connector is right under the seat. It will make programming more difficult, but the other option is to generate a ton of fault codes while scoping out the bike.
Though my scope does have a can protocol decoder.....
