Just made a few trials with different gearboxes in Tor Poznan:
the "usual" Mazda transmision which is syncromesh with manual clutch irl in the road cars and in the older Cup car works realistically as expected.
Race start with the clutch, "forgetting" clutch engagement when shifting is penalized with gear box damage.
Its possible to use the clutch as a switch ( just tap it) and so cheat the game but I will not start with that kind of shenanigans as it would mess up muscle memory for my irl manual car.
To be frankly, without "shift lockout" which only allows shifting when the clutch pedal is depressed for at least 90% this is also kind of cheating.
I also can´t imagine how this would be quicker as moving the shift
lever takes longer and you have to modulate clutch and throttle, for "driftfree" downshifts even simultaneously with the brake/ Heel´n´Toe.
Just realised i didn´t try Autoblip
I tried H-pattern with autoclutch but was discouraged fastly as the "sounds of destruction" appeared when shifting without clutch signal.
I´ll stay with 3pedal driving with a sequential stick, I believe the manual clutch gives an advantage at Race Start and the upshifts are full throttle /Flat Foot Shifting.
For the the downshifts I just blip the throttle, braking is completely left foot.
In all fairness, that would only be "realistic way" for the current modell MX5Cup which has a sequential gearbox.
OH, BTW, Autoblip and Flat Foot shifting can be had with aftermarket tunes even for road cars. I just didn´t choose the latter because it stresses the drive train even more than normal track duty and I´m not slow on track because of the shift times.
( And in the GT86 Cup at VLN it was prohibited by the rules
)
