Paddle shift, Sequential gearbox - Rev. match when using clutch

Hi team,
is it somehow possible to activate rev. matching when shifting down with clutch?
This could be quite usefull in slippery conditions.
If, yes please give me little hint.
Best Regards, Rainer

There is not enough time for rev match with sequential gearbox . the only option to have that done is to get gearbox barrel driven by brushless motor ( i think one company is doing that at the moment) so you can “stop” shift between gears and wait to rev match . with current setup you can only manipulate blip level to achieve smooth as possible shift

I mean when the clutch is pressed there is enough time to match the revs before the clutch is released. (what you would do with heel and toe).

Yes but shift process is finished … and strategy is not active anymore…
maybe would be possible to implement somehow revmatch for h pattern but not sure how would this work this maybe difficult

Currently, there is no option like that for a sequential shifting.
Greg mentioned that the gear shift process will be finished when the next gear is engaged, which means the strategy is not doing anything anymore.

We would have to add a special case for the downshift with the clutch pressed.
We can add it to the list, but it will be a low priority for now.

Thanks, I understdand that it’s not top priority, but I’m very glad if you added to the list.
It could be quite helpful in rain with bad semis or slicks.
That’s really great support, guys. (even if you don’t add it :wink: )

I think there are 2 things to take into account when creating a down shift strategy, depending if its is a dog engagement (seq or H) transmission or syncro transmission.
Firstly as mentioned, there is the ‘rev’ matching to engage the gear dog (or syncro). In practice, as mentioned, this is too fast in a sequential gearbox, that it doesn’t tend to matter, and has no practical benefit. In a syncro box, a rev match when the clutch is pressed can be of benefit to help prolong syncro life by reducing the amount of ‘braking’ it needs to do.
Secondly, a throttle blip on downshift is useful, not for the gear shifting process, but to reduce the delta of wheel speed and the axle torque (engine braking) to the tyres under down shift scenario. This is particularly important in wet conditions as mentioned above, to reduce the chance of locking the wheels under rapid down shifts.
