Wed night Fun Races (2021)

Ok - Motec.


There’s nothing wrong except with your brain-to-foot interface…

I’ve dug into Motec. These graph excerpts show throttle position (green) and gear (blue) against time (speed is also there but not part of this discussion). Note that the horizontal scale (time) isn’t always the same as I did this quickly.

First image is a ‘good’ upshift. It shows I lift 100% (might not be necessary, but it’s what the data says I do) almost in sync with the tug on the gear paddle.



I’ve made Slicker shifts with less zero time, but anyway…

Next up is a mis-shift requiring a second lift:


Note that I do t seem to have needed a full lift to re-engage the gear.

finally, for completeness - here‘s a sequence of downshifts with manual blips:


Interestingly (I wouldn’t have guessed myself) I lift the brake (yellow-green graph that is labelled Steered Angle…!) just as I blip the throttle… It also looks as if I initiate the blip *before* pulling the downshift….

Then again, the Datsun is not a very sophisticated car anyway. So it adds to the experience of driving these crazy 70s cars. It appears to ask for just an extra skill, just like double clutching in cars with crash gearboxes of preselector-gearboxes...
Try to drive 30s sportscars (real not virtual) and it takes some time to get used to these quirky old things. In that period of time lots of cars had even throttle and brake pedals different (throttle in the middle and brake to the right). In the end you love it.... (untill you have to make an emergengy stop)
