The ECU, including the program, is completely defined by the part number. There is no code difference for California versions of the Tenere.
Ok, then it’s maybe down to variation from one example to the next, who knows. The CA models have different emissions equipment, in spite of ECU tuning that might affect drivability too, otherwise why bother with a separate version?

Fwiw, the abrupt throttle response was documented by Rider Magazine on their long term review of the 2015 Super Tenere ES. If you'd like, scroll down to the final entry (3rd paragraph at 11,196 miles). Author Greg Drevenstedt addresses this topic. I'd also take a look at the reader comments section following the article. Here's the link:

Yup, mine was done right from the factory. The only time my injectors turn completely off is when I roll completely off the throttle. Speeding up or slowing down, she reacts just like any other bike. I love the boat anchor engine braking.

Yup, I love the engine breaking, when loaded down with gear and coming down a steep grade on gravel the engine will hold that beast from running away. When you ride mountainous areas you appreciate what Yamaha has done with this feature....Thus "ADVENTURE BIKE".
Sport mode doesn't belong off road, Yamaha made the mistake of labeling the modes wrong. Its more OFF road mode and ON road mode.
As for S mode the THUMPY twin with its 270 crank definitely makes for getting use to the throttle as low end grunt is what this engine is about.
Its a truck of a bike, ya many complain about the throttle and Youtube/magazines tend to drive these issues but generally you hear more of the complaint's then those that are happy with it. JMO
If it doesn't fit your style change it, that doesn't mean its a problem, maybe Sierra and I got the only perfect S10 from Yamaha LOL.

In this case we are the problem children.
I love the fact that this engine feels like a monster single cylinder more then a twin. The torque and traction the Tenere can generate on loose surfaces is unreal. No rev's needed, just load it and go. Love it.
The only engine I can compare for that grunt is the Boxer from BMW.

Yes, I have to be careful if I get too "inspired". Or the back tire will break loose; or lift the front end. So, when I read how the first three gears are limited, I get confused. Mine is not that way. Or, if it is, I'm glad. More would not be better.

I flash all my bikes but on the Dyno. I had my Zx14r flashed for more power, earlier opening of secondary throttle flaps and the fan cutting in at a lower temp plus Rev limiter extended 500 rpm and speed limiter removed. She puts out 214bhp at back wheel.
I flashed my S10 to have more grunt coming out of corners and smoother throttle response with the fan coming on 5c earlier. She puts out 102bhp
Horses for courses but it was me that decided.

My 2012 model (I added to her a 10th anniversary sticker) has that jumpy feeling on S mode...
