I did. Doesn't work. The axis is not really speed. It's some conversion factor for calculating gear. Gears are 5, 4 and 3 to 1. So if you put the lauch rpm, it uses that for gears 1-3 which is nice...

Yes it does work, you have it wrong then, in ms42 put 500 in last box and 450 in middle box, right box should be your launch rpm

For those, who say it does not work, I can confirm that this method DOES WORK.

Just did this on my friend's C6 ECU. Works nice. Value of 500 seems to be around 10km/h, value of 450 seems to be around 15km/h. The higher the value the lower the speed. Something tells me this is just defined a bit wrong.

Yes it's defined wrong. It's not speed but value to be used for gear calculation.

I only wonder where else that axis may be in use. Like in MS41.2 when you change RPM Limiter table axis, you also change the axis of VANOS table.
So far, no abnormal behavior was noticed with this setting.

Hi, can you show your working settings? I must put values for example 500 and 450 in axis address? I want to achieve 3k rpm launch control and 6784rpm limiter above ~5km/h...

Changed axis and LC works.

believe me or not i still don't understand where these tweaks needs to be applied.

Ok
thanks to Tipsb things are a little bit more clear.
i've edited all the axis for each hard/soft limiter to 24/450/500 and set the limiter to 7072 for 24/450 and 3616 for 500.

But (..but):

- it is not holding the rpm, is some tweak necessary to the Clutch switch section too? (even with clutch disengaged rpms wont go over 3616, obvi without moving)
- depending on the angle of the pedal, I feel a noticeable difference, with little gas the rpms bounce seem much smoother than in WOT.
I have Richard's POP n BANG mod, this works around 3000 rpms, i can clearly feel that this is influencing the whole thing that spot as engine is literally shaking on full gas (that's why i tried to raise the LC set point to higher rpms).

any idea on how to make it, first of all, properly works and then how to combine LC to pop mod without any side effects?

thanks in advance

I figured out how to set an rpm at a stop and have all gears go to increased red line
