    Diesel engine sound is different and turbo sound changes depending on if you have DPF on/off and straight pipe changes the sound even more, gasoline is the same but with straight pipe it also changes

    I think if you put all the stuff you made for ETK 800 into one pack it would be epic

    I must preface that I am by no means an expert in transmission design and that all the information that I've found is available on the internet. The addition of a gear indicator in drive is a nice addition, and the shift logic feels pretty good for the petrol 3.0L 8-speed. However, the base game gear ratios and minimum gear for the converter lockup for the petrol 8-speed automatic are accurate to the real-life ZF 8HP45 and don't require changing. Also, I'd suggest reducing "gearChangeTime" from 0.3 to 0.2 to reflect the 8HP's official shift time.

    I started with the real life gear ratios for ZF8HP and torque converter lockup but couldn't tune it right. Gears were spaced out strange from each other and there were situations where rpms were too low or rpm needle looked jerky so little by little i landed on a hybrid variant of real life ZF, my beamng modding knowledge limit and my taste/feel of how things should happen. It even uses older style lockup logic where 1st and 2nd gear and below 2000 rpm on all gears it's never 100% locked up which is totally wrong on paper but looks alright when driving. Also i tried improving the shift points curve in the lua but it's still not perfect. So you can treat it like the most optimal solution for now and not a 1:1 copy of a ZF 8 transmission. I will reduce the shift time in the next update.
