Is it me or lots of cars in Historix 1.9 with grinding tranny are very forgiving.
When I use grinding tranny with some other mods if I not rev enough or over rev when downshifting I will either lock wheels or my car will shoot out as soon as I release the clutch, so I know that grinding tranny is set up and working correctly.
In Historix tho most of the cars dont mind me missing power band.
IIRC Mercedes is rather vulnerable but Porsche 911 RS 2.8 and Cobra (I think it was porsche and cobras I dont remember atm which cars exactly) are more forgiving I dont think I locked wheels on either of them even tho I am sure I missed powerband a lot.
I would need to connect all the pedals and wheel to tell precisely which cars are oblivious to my terrible shifting practice
First things first: If you're not revving enough or over rev when downshifting you shouldn't even be able to get it into gear, so you shouldn't really be experiencing lockups because of that. =)
But anyway, the cars are pretty forgiving when you for example initiate a drift by shifting down and letting the revs drop before engaging the clutch. I'm guessing this is due to the tyres being pretty forgiving when sliding and perhaps there's some slip in the driveline when that happens. In some mods, yes, you would spin out instantly, but these cars are pretty good about it.
And about how some cars might be easier with Grinding Tranny than others, that's pretty big jumble of different things interacting. Gear ratios (especially how large the gaps between gears are), rev limits, how quickly the engine revs up and down, all of that plays a part in how easy the gear changes are. Some cars with very wide gaps between gears are more difficult to time correctly than others. But if you learn your car inside out you can figure out the correct timing for most every situation. The DB4 is one of my favorites and I enjoy driving around the Nordschleife in it, never using the clutch when changing. The time to wait between every upshift and the amount of blip required for every downshift is different and very situation dependent, it's great practice and immensely satisfying when you can go a full lap without any missed gears. =)
EDIT: On the topic of desynchronized speedometer, am I right in my assumption that rFactor doesn't really allow you to make needle gauges with a non-linear scale? I've seen plenty of cars where 10, 20 and maybe 30 are really bunched up on the gauge and then 180, 190 and 200 are wide apart.
Besides, how accurate would the needle speedos in racing cars be anyway? They take their input from the gearbox, so wouldn't changing the final gear would necessitate a readjustment of the speedo anyway? You're just supposed to set your top gear so that you barely hit the limiter on the longest straight/fastest part of the track and not worry about specific speeds anyway. =)
