LDU parameters to reduce power

Hi.
Can someone please guide me a bit how I can change parameters to decrease power output?
My first idea was to use the current limit but this seems to set the inverter/motor in error state if triggered?

I would like to have the possibility to adjust the power output in a controlled way.

Thanks

throtmax, you can reduce it to limit max requested throttle which reduces power.

fslipmax also seems to reduce power. I'd check out the parameters threads and basically do the opposite of everyone raising power levels.

In the past when I’ve had OC events doing hard pulls (usually occurs during wheel hop), it’s fslipmax that I’ve backed off.

Not had one now in a few years. However, the firmware version can have a big influence too. I recently upgraded from 5.20 to 5.35 and the latter made the car a lot more powerful, even with an identical parameter file.

Thank you all very much for the input.
tom91: I like the simplicity in this approach. I plan to send some can messages to be able to set different "power levels" and this should be easy.
Others: Will check parameters more for tuning. :)
