Diff ratio editing

[Highway]

is there anyway to change or edit the diff ratio

[Fury6]

Sure, you'd need to add the transmissions to each truck you're interested in though.

Here's my own definition for an Eaton Fuller Super 18 gearbox with 4.11 rears:

You can see the parameter called 'differential_ratio:' near the top, right above the gear ratio definitions. That's what you'll need to change to suit. I have a whole range of these I use for all my trucks going from 2.80 up to 4.17

[Highway]

so where do i find that or is it a mod

[Highway]

bump

[Highway]

bump

[Fury6]

Yep, you make a small mod that adds the transmissions to whatever truck you want.

Here's a link to one I just made as example: https://drive.google.com/open?id=0B9uM3iEXaWnYNkZWdFJVV3IteG8

It adds a range of super-13 and super-18 gearboxes with various rear-ends for each of the vanilla trucks. Hopefully google-drive will let you d/l it...

Just drop that folder into your mod directory and activate it, if you want to use it directly.

[Highway]

how can i do it for a truck that i downloaded

[Fury6]

You'll have to make a mod for that truck using the folder I linked to as an example. Which mod is it?

[Highway]

this is getting over my head, what do i use to make a mod

[Fury6]

notepad, this is the easiest type of mod, it's just a unit file edit. Which truck mod were you looking at doing this with?

Ok, drop this folder into your mods directory and activate it... :) (I'm hoping google drive lets you d/l it, haven't tried sharing stuff via google drive before...)

[edit] If it lets you d/l it, it will zip it up first then send it down. You'll need to unzip it into your mod folder.

[Highway]

it shows up in the mods but hasn't shown up in the gearbox selection

[Highway]

doesn't matter how or where i put it, its not showing up in the upgrades

[Fury6]

ok.. make sure you've unzipped it. It won't work if you just dropped the .zip file into the mod folder. You need to take out the folder that's inside the zip file and drop that folder into your mod directory.

[edit] I have it working here with that t600... so I can only assume there's something wrong at your end in some way.

[Highway]

yeah done that, even placed the *.sii files into the mod folder to try something else
