Doesnt look like wheelspin is much of an issue at the minute ?

What do datalogs of your launches look like as far as wheelspin etc is concerned ?

I have to hold the rpm at around 4000rpm and slip the clutch until it stops wheel spinning, then I give it full throttle. It's wet launches where I suffer the most.

The clutchless gearchanges are making a big difference with preventing wheelspin in 2nd. It used to break traction back when I used the clutch.

The flat shift may help improve the times a little more. The replacement gearbox sensor came on Friday so I'll fit it this week.

I'll pull the data logs from the S80 and post them on here.

It's on a hexagonal shaft and getting it straight can be a pita
So I just live with it. Can't say I notice when I'm driving..

Has anyone using this noticed anything strange in logs ?

I tried a couple of very slow tractionless launches earlier.

Until the turn off speed, only one driven wheel registers a speed. The right driven wheel will stay at zero until the undriven wheel hits the turn off speed then they all read as normal.
Left driven and undriven read as normal the entire time.

When launch is turned off, all wheel speeds record as normal.
