mmm... okay, in wikipedia I had found this, I understand that in "Drive" mode I would not have to cut injection, only on "P" and "N", no?

If you go “old fashioned”. The autobox has a rod connected to the throttle
so it knows how hard your driving and if to change early or hold a gear.
one would expect the rev limiter to be active at all times.
to prove this, get somebody to change it to something silly like 3200 rpm
or unplug a load of engine sensors so in limp mode and eat sleep and repeat

AT speed limiter recorded in ECU transmission
And for popcorn mode, you need to edit the torque map in the DDE engine (ecu). And it will work on P and N
