Any success with 2022-2023 tuning/EU Emissions Torque Limiter removal?

Im not talking about the pedal commander, im talking about the pedal box. Default throttle response is at 65%, pedal box sets it to 94% so even if you go max throttle within a millisecond, you wont get max power until the set throttle curve is done. Having a more aggressive curve will give u max power sooner when you twist the throttle, instead of as it is now where you twist the throttle max but the signal to the engine will have a slow wind up curve, like slowly twisting the throttle on a wired throttle. Probably wont do alot but it will help with the slow response the ryker comes with by default. Feels almost like turbo lag.

Pedal Commander, Pedal Box, Sprint Booster, all variations of the same thing.

Your statement "as it is now where you twist the throttle max but the signal to the engine will have a slow wind up curve" is not correct. If you twist the grip 100% you get 100% signal to the ECU, with or without a Pedal Box. Unless you are in the Ryker's Eco mode, the throttle is going to open fully virtually immediately. The curves that Pedal Box shows is the signal to the ECU, not the signal out of the ECU to the throttle body. The Ryker's default mode is not a slow response; it is only slow in Eco mode.

I extensively tested a Sprint Booster decades ago. Drive by wire throttle bodies have a TPS (Throttle Position Signal) to the ECU so that the ECU knows exactly the position of the throttle opening. I recorded the accelerator pedal signal to the ECU and the TPS signal to the ECU with and without Sprint Booster. The TPS (and thus the throttle opening) tracked the accelerator pedal signal to the ECU with virtually no lag, with or without Sprint Booster, and the tiny amount of lag was the same in either case. Pedal Box response is not going to be any different.

I can make the same measurements on my Ryker, but I already know what the result will be.

Then it must be an EU thing along with the emissions limiter because people who use them says it gets way more aggressive on the launch and seeing people launch their Rykers in US isn't anything like it is for us in the EU. The power limiter lets go after 80km/h and after that its way more responsive, both on power and throttle, at least on mine.
And a quick max throttle at low speeds feels sluggish in Rally mode, feels like it has a delay....

Interesting. A quick full twist of the twist grip on my 2019 Rally will spin the rear tire in any mode but ECO.

Same on mine but it chokes out quick. If I do a quick max throttle and back off again, you can feel how slow it reacts. When I go 80km/h or above, it's instant.
I did a comparison with another guy who has a stock 2020 and he pulls away from me without issues, and that's why I'm getting salty and want the limiter removed.
Not sure if they messed with the stability systems as well, cause I can't take corners as hard either before it starts choking off the power.

I have a 2020 Rally and it gets sideways even in eco. Riding in the rain in eco starting on a hill it spins the rear tire at the slightest throttle input. I have no mods to the trike.
