Love your work. You do an awesome job.
Apologies in advance for the length of this post.
I was wondering if you may help me with a query regarding transmission setup?
I am using your calculation spreadsheet, which is brilliant.
I know spreadsheets fairly well and have checked the formulas, and also checked the results by hand with a calculator, so there is no issue with the gear calculation sheet.
So ... I'm having an issue essentially with 6th gear.
Using your system I'm finding it difficult to get a launch low enough to not spin the rear wheels on a particular car.
So I've slightly altered your start procedure, other than that I've followed your system.
Instead of going up to 70% final gear in the first step I've actually gone down to around 40%.
From there it's set the max speed to minimum, spread gears as normal, lower final gear to 2.500.
So basically your system with a slight change regarding starting point on final gear scale.
I chose to go down because at that point on final gear, then max. speed to minimum, then first gear at 0%, final gear down to 2.500, I have a perfect launch.
So I then reset the gearbox to standard, then set same final gear start, max. speed to minimum, and worked out my 6th gear ratio to match the track top speed. (When final gear is back at 2.5000 of course)
I can't see anything that I'm doing anything wrong.
So knowing my 1st gear is set at 0%, calculated my 6th gear to be at 38%, I then proceed to spread the remaining gears evenly.
The issue is that all gears 1st to 5th look beautiful on the gear line diagram.
6th gear however is separated way too far from 5th and comes in at far too low a rev count.
I cannot work out why this is happening as I'm certain I'm not making any silly errors along the way.
An adjustment by eye on 5th gear to even out the spread on the gear line diagram can be a simple fix, but I would much prefer things worked as they should and I didn't have to revert to 'guess work'.
Any thoughts on how or why this might be happening?
Is my start procedure, although different, still okay, or is it the cause of my issue?
I realise the % ratios are a bit weird, but I find it easier to do it that way.
There's perhaps a more regular solution, and perhaps I'm doing it this way because I'm being lazy, but I still don't understand why 6th gear simply doesn't fit nicely like the rest if I'm essentially using the general concept correctly.
I appreciate you taking the time to read this, and trying to get your head around what I'm describing.
(Again, sorry for the long post but difficult to describe in a few sentences)
