I can see the values for gear box ratios and final drive but how do you accommodate the primary reduction gearing value?
Found it, its just called Ratio :)
and..
How do i lock ratio options to a certain gear i.e. i have 2 sets of gearbox gears P1() an P2() each with 6 ratios, how do i map set P1(1) to 1, P1(2) to 2, P1(3) to 3 etc and P2(1) to 1, P2(2) to 2, P2(3) etc.
At the moment i have 6 gears and 12 gear options but i can make more than 2 choices for each gear in the garage :(
It might be a bug... :(
I checked with the default 125.
In the garage sometimes you can only select 1, sometimes 2 and sometimes 3 ratios/gear. Only 2 gear sets seem to have been defined (i do not quite follow the logic as it seems to have an odd numbers in the ratio matrix) but depending what you select for one gear position the available options for the other gear get altered or locked out.
Thanks
It assumes that gears are monotonic: the ratio of gear N will limit the available ratios for gears N-1 and N+1.
Slightly lost as to how you model a box with 2 fixed gear options then. Any ideas as i would of thought this is quite a common problem. Otherwise i end up with funky gear options in the garage
I was hoping it was defined like this
My box
gearbox
{
gearing
{
;P1 is first gear shaft option
;P2 is second gear shaft option
ratio0 = 14, 31 ;p1 first
ratio1 = 16, 33 ;p2
ratio2 = 19, 31 ;p1 second
ratio3 = 17, 29 ;p2
ratio4 = 19, 26 ;p1 third
ratio5 = 20, 29 ;p2
ratio6 = 22, 28 ;p1 forth
ratio7 = 25, 31 ;p2
ratio8 = 26, 30 ;p1 fifth
ratio9 = 26, 30 ;p2
ratio10 = 25, 26 ;p1 sixth
ratio11 = 27, 29 ;p2
}
NumGears = 6
Gear0 = 0
Gear1 = 2
Gear2 = 4
Gear3 = 6
Gear4 = 8
Gear5 = 10

If you mean that you want to have 2 gearbox sets with ratios [r1a ... r6a] and [r1b ... r6b], I think you can't in GPB.
Thanks again for the info. Seems odd, i would of thought it would be common for superbikes/kit race bikes.

Don't know. I've heard about categories with fixed gearbox ratios, but once you're allowed to touch it, you can probably change each gear.
I was hoping the logic was better, so for example;
Gear0 = 0
Gear1 = 2
Gear2 = 4
Gear3 = 6
Gear4 = 8
Gear5 = 10
if i define gear1 as starting at position 2 and gear2 as starting in position 4 it would only allow ratios 2 and 3 for gear 2 and 4 and 5 for gear 2 etc.
You could then have complete control of the range of ratios applicable for that gearbox position. At the moment you can end up having impossible (in real life) gearbox ratios.
I now realise that it is just a list of indexes :(
I think what GPB does is OK with respect to real life.

Can you give an example ?
The problem is that in garage view with the example stack i can end up with ratios that should only be applicable for gear4 being available to gear3 and gear5 depending on which option i have selected for gear4. Thus i end up with 'overlapping' ratios.
The ratios i have used are the stock and HRC alternative gear options for an RC51 (from HRC race kit manual gearing table) so i know they are realistic combinations.
The logic for moving through the options is a bit unfathomable, i am sure that in real life you only have limited options for gear ratios in each position but in GPB i cannot create a constrained list of options.
Do you mean that in real life you can't put a ratio that is intended for 4th gear on 3rd gear ?
How's that done ? gears have different splines to the axis ?
We would need some of the real life racers to comment on how practical it would be to construct you own custom gear stack. On issue would be whether all the gears had a common spline size and correct width and drive dogs to be used in a different position.
