Best to get a consistent launch control

[Botasjr]

hi

since i update the firmware to 1.167, im geting strange launch control.
this is a 1.6 psa engine with peak power at 9100 rpm and a 1st gear that reaches 75 km/h

with previous firmware version, i set the rpm to 6500 rpm, and the engine stays at 6500 rpm with a very fast cut and power,
but now
sometimes, it works good, and other times the engine cuts a lot, like a fuel cut, and i have this function disable like you can see on the picture.
i have tried with ignition retard, and it seams worse.

how can i have a constant fast rpm launch control?

interpolate ign. angle and interpolate spark cut are on by default since it was implemented, are they on or off?
post a screenshot of our launch settings.

yes you have interpolation on, turn it off.
activation is at 6000, cut off rpm at 6800, with interpolate spark cut on it will start by 1% spark cut at 6000 and 100% at 6800.
and you can set the activation at 6500 and cut off at 6600.

that is what i have in mind
but i need to test it

have a small gap between the activation and the cut rpm.
