SUPPORT: Cars Performing Outside PI [UPDATED 9/15 10:16 a.m.]

Hi can you please check all the cars, because i think its a drivetrain issue when 4wd/rwd converted adding a race diff/ 100/100 accel…
Also the benchmark and calculations go very weird after drivetrain swapping cars, for example adding a tyre width can add 2 sec to your 0-100 time.
From the many cars ive tested with EMW, 90% were v similar to the mini, fiat x19, some the same impact, others a little less and a few only noticeable on fast tracks.
They were all performing way above there Pi levels, only when coverted to either 4WD or RWD, adding only a race differential would almost half the 0-100 benchmark.
Then building the car alongside the benchmark, adding parts that only improve your 0-100, you can drastically alter the cars Pi.
All the above is done without adding power or reducing weight.

Mazda Rx3
Mazda mx5 all
All VW
All Ford
All Renault
Every single car below B600 is open to exploit, the above is only a few.
It would be really great if the above issues could be fixed asap, because FM6 is a v good game that deserves to be working correctly, thankyou.

The root of the cause is FWD/RWD → AWD conversion and to a lesser extent FWD → RWD conversion, but both need fixing.

Is there any news on this yet? This is really spoiling things right now.

needs fixing ASAP!

FWIW, I ran a quick test and it’s not just selecting the race diff that causes it, it’s merely changing the diff. I set up a new Arbarth build, which isn’t usually capable of getting to 100mph, by doing the drivetrain swap, doing the race diff mod then adding engine bits til it could get to 100mph. The 0-100 time was something like 44s - no bug. Then when I switched it BACK to a normal diff, it dropped to 18s and the top speed went from 101mph to 124mph. Weird. Trying it the other way round would get the 0-100 down to 14s! Yikes! SOooooo, in conclusion, it is the act of changing the diff which triggers the bugged code, rather than specifically choosing the race diff.

I can confirm the Toyota Trueno can do this. I saw a time set in D class by a guy I know is not that fast so I decided to look into it.

After AWD swap and race diff added, the car’s 0-60 decreased 1.4 seconds. The 0-100 decreased 9.2 seconds. The top speed increased 9 mph. Those numbers don’t make any sense.

There were no performance upgrades added to car.

When you do an AWD swap doesn’t it also change the transmission? I know we’re used to looking at launch when we do the AWD swap, but it has always changed other aspects as well. When you switch something to RWD or AWD you are changing the entire drivetrain not just the diff. If you did this on every car you would see some have an increase in top speed and some have a decrease. All should see an increase in 0-60 and 0-100 as you would in real life. The Nissan GT-R Black would do this in FM5, but to a greater extreme.

The 3 cars they are looking at are having issues with a 100% diff. Not necessarily the drivetrain swap. Try putting an AWD swap on the Hellcat and turn the diff to 100% and see what happens. I’ll try it tonight.

Of course 0-60 should decrease some with AWD.

Go do this yourself. It’s only after you do the swap and THEN install the differential that the very odd ratings appear. When tuning, the accel by default is already at 100 for both accel stats. Tuning didn’t appear to me to drastically change the stats for this car.

The differential doesn’t give insane ratings when the car is left in rwd. It’s only after you swap drivetrain and then place differential on the car that things go crazy.

A differential will not make virtually a stock car into a super accelerating monster (especially on top end) and increase top speed by 9mph.

Sorry, this is not legit. Look at the numbers I posted. Does that make sense for a low hp E class car?

The glitch doesn’t seem to mess with newer cars. I’ve tried it with every car I’ve tuned.

Adding just AWD with a diff and no performance mods, should technically slow the car down a little. As it should be adding extra weight to the car. It shouldn’t be going faster just from an AWD swap and diff upgrade alone.

The Audi Quattro would like to disagree with you. The grip and ability to get the power to the tires out way the nominal increase in weight. That’s like saying a 6 cylinder is faster than a V8 because the V8 weighs more. Go to any drag strip in the world and you will learn that AWD has the advantage.
Top speed can be different. In the game your transmission is often upgraded by default along with the rest of the drivetrain. This is what causes there to be a higher or lower top speed.

It’s still not legit.

The switch to awd is minimal in terms of effects on the stats of the car. Adding an upgraded transmission also had minimal effects.

It’s only when the differential is added that it goes crazy.

You obviously haven’t looked into this stuff so stop trying to defend it as if it’s accurate.

Seems the Bathurst Rivals challenge has a glitch as well. Unless it’s because I changed a couple of settings, but all I did was change it to manual shift, and changed the braking to ABS rather than assisted, but now it wont save my times! So annoying!

“Ferrari” Dino does not seem to have this problem and it is an old car. Someone should confirm though. Just in case.

I tried to do the Hellcat last night but a swap is unavailable for it. I’ll try some other cars tonight.

What you’re saying is you are getting those numbers when you upgrade the dif not the driveline? Okay, that’s what I’ll look for.

Swerve the above post was my response to you not the one you replied to. I agree that the dif should not make that much of a difference. The post you did see and reply to was my response to someone saying AWD is slower because it’s heavier.

You don’t need to agree with me just please post the correct response to the correct post.

Its not the diff thats the problem. The cause of all the problems is the AWD and RWD swaps i.e. FWD/RWD → AWD and to a lesser extent FWD → RWD is just causing the algorithm for the rest of the upgrades therafter to go awol…AWD should be slower if 200 odd pounds is added to the car, yes the 0-60 and 0-100 may increase, but if it does that increase should be miniscule, the initial burst of accel will be faster, then the rest shouldnt…afterall you just added lots of pounds on the car. The increase with the swaps is massive, its like getting 50 odd hp extra without ever putting the upgrades on. To be honest the way some of the cars accelerate its like putting 200hp extra in it.

So at the end of the day it needs fixing, its being investigated and it needs to hurry up because half the game is pretty pointless to play at the moment, partly because a wipe is coming which should involve so many cars and partly because cars have been banned from online use.

This needs to be the absolute main priority above any small and unimportant issues that i keep seeing people complaining about.

How most of these issues get past testing is embarrassing for a company like Turn 10. The process they follow just isnt working or the people they hired arent very good at their job.

How long does it take to investigate aswell? Run the code in debug mode and breakpoint the code that relates to the conversions, then debug the upgrades, take a note of whats going on…Repeat the same process with no conversion upgrades and see why one is so sqewed compared to the other…then fix it.

It’s surprising how fast these bugs were found too. Somehow these get overlooked and we find them within the first week it’s out. Seems testing PI was not a priority in this game. This can be said for previous games too (dodge dart + viper motor fix/F4). Our club is hoping this gets fixed soon as well. People are running the other mentioned glitched cars due to being available to race online still.

Okay Swerve. I have gone through a lot of cars and have found a lot of consistencies. It only happens on swaps. When going from the stock/street dif the 0-60 and 0-100 times decrease (get faster) and the top speed increases. It also changes the dif settings. If the settings are put back to same as the street dif the 0-60 and 0-100 times increase (get slower) and the top speed decreases from what was on the stock/street dif defaults.

There is nothing wrong with the normal swaps and adding the dif. Think of it as going from a stock transmission to a race (ignoring the weight drop) with a different gear ratio. That’s all it is.

Please test this for yourself.

The vast majority of cars are ok.

Here I found another one for you…fiat 131 Abarth

Stock:
0-60 = 8.2
0-100 = 24.0
Top speed = 130.0mph

With AWD swap only:
0-60 = 7.7s
0-100 = 23.5s
Top speed = 128.8 mph

As to be expected awd allows the car to accelerate a bit better but top speed goes down due to weight. Seems to be reasonable, right?

With AWD swap and race diff:
0-60 = 6.4s
0-100 = 16.9s
Top speed = 135mph

Now this is where the craziness happens. How does a diff make the stats look so good?

Up until now I’m guessing everyone thought the Fiat 131 Abarth was ok. Sadly, it’s not. :frowning:
