I'm sure this is very health for the engine ;)

Done with TL, cut fuel top end in a very short rpm range.

goshhh....dont do that. that nice sound will cost you a lot.

you should give a very small amout of injection on the final rpms.

so on the launch map....you adjust the rpm axis-and make the rpm closer.192108

This ecus turn off the main injector at 5300rpm , so if u put the max IQ u want to the end of the axis , the car will cut like this .

so if i understand this right...the fuel is cut by the torque limiter first,before it reaches the max rpm on launch map.

Don't need to use in-gear torque limiter (launch control map") can be done with the 21X3 torque limiter.
You want to cut the fuel suddenly in just a few RPM for example at 4200rpm you have 50mg, and 4202rpm
you have 0mg. Modify the axis data. Try a few different things to get the desired effect.

For me, I won't be trying it lol

Another example if you don't want to rev the engine too high

Or just find the single RPM Limiter to turn off the injectors and change it for the RPM u want.
