Less top speed?

[v-tec civic]

I'm bussy with driving speeds of 300mph+ but yesterday i was driving with the tvr cerbera speed 12 and i tuned the gearing a bit to more top speed and then the car accelerated like it was stock even when i put the auto settings to 25 and the final drive to 2.500 it only got 1 or 2 mile more top speed. when i set the gearing the same as first it accelerated much faster as it did the first time!! Then later i took the nissan rg92p to the course and after tuning the suspension and doing a few tests it starts accelerating much faster. so i brought the gearing back the same as first and it accelerated much faster as it did before with the same setting. Now today i have bought a toyota gt one (black version) and i was testing and tuning these and it start doing the same things after i while. then i gave it the body refresher and it runs normal again for 1 run. but in the second run it already accelerated much to fast with the same setting!!! Is this a bug in the game or something? Because i can't drive high speeds this way.

you have to tune the gear ratios to fit the track and car's powerband.long gears are bad in cars that have no power until high revs. same goes other way round. you have to find well-balanced gear ratios.

the set-up you use now would look like that it's fast, but actually it's too long for any car in GT4 ( not counting the Tank Car ).

put the final ratio around 3.700 and adjust the individual gears so you get best compromise between acceleration and top speed, and use the final gear when going for the top speed, and work with your NOS timing. suspension and downforce settings also play big part in this. and so do tyre compounds.

I know but that isn't the point. Lets take the gt one as example. I put the auto on 24 and the final drive on 2.584. The car needs more acceleration for a higher top speed so i put the final to 2.621 as example. when i i drive around the testcours the car acellerates very hard. normally he wouldn't do that with those settings. so i put hte final drive back to 2.584. And again it accelerates very hard and first it didn't with the same settings! So i put it to auto 25 and final 2.500 and still it gets away with spinning tyres in 2nd and drops out at 280 mph. I also got this with other cars wich suddenly accelerates much to hard for those settings. This is realy weird.

GT4 appears to store, like GT3, two different sets of Final Drive settings.

The first is Final-Drive-before-Auto-gear-adjustment. The second is current-Final-Drive-setting.

So the two following scenarios, despite displaying exactly the same values, produce different effects:
1. Final Drive to 2.500, then Autogear to 24, then Final Drive to 2.584
2. Final Drive to 5.000, then Autogear to 24, then Final Drive to 2.584

(1 should accelerate quicker than 2)

As soon as you adjust the Autogear, it resets the first, unseen Final Drive value to whatever it's set at at that time. When you then adjust the Final Drive it retains the original value at the time Autogear was set and also takes note of the new value. That's why when you altered Autogear the second time, things went a bit odd.

This (if you can understand it) is a good explanation of why GT4's Autoset transmission setting can make a huge mess of your gearing, or make it perfect. From here rises the so-called 'tranny trick'.

It can take a lot of time to get fully used to and familiar with GT4's way of working with gear ratio setups, there are (complex) ways to explain it fully but the best way to unravel how to apply gear ratio setups is to test out different settings and figure out what does what, and then (if you really want to feel confident with it ) why it works how it does.
I like to think I know what works, and maybe why as well, but we're always learning
Anyway, hope to see you apply what you learn about gearing in the 300mph Club 👍

can you explain step by step on how you change your gear? like what you do first, change auto or final drive (very important)?
I am a bit confuse with "normally" part.
How do you measure accelerates very hard? ghost car? data logger?
