Car tunes changing by themselves

Question here guys,
I have done some tuning in every Forza game…not a ton but some tuning.
Now my question…If I have more than 1 tune for a car and I go into test drive at a track ( Maple Valley ) and adjust the tune installed on my car it adjusts that tune but also the tune I didn’t have on my car.

As an example 2 tunes, a grip and a speed tune for a car. Grip has tire PSI @ 28 and Speed tune is at 30 PSI for the tires. I have the speed tune on and driving in test drive at Maple Valley. I decide to lower the tire PSI to 29 and go back to testing. If I then back out and load the grip tune my tire PSI is also at 29 PSI up from 28 but I didn’t change that tune only the speed tune.

How can I make 2 different tunes for a car? Every time I change 1 tune they both change so it’s impossible to have more than 1 tune per car.

Didn’t Forza 5 or 6 have a bug like this for awhile?

Time to whip out the ol notebook.

I have noticed several tuners have a grip and speed tune for the same car shared online to download. Are they the same tunes ant they didn’t realize they were both changing when any adjustments were made in essence making them both identical exept the title?
I only noticed because I made 2 tunes with different parts and was comparing them against each other…every time I changed a value on one tune the other changed too without me changing it. This makes it impossible to have 2 different tunes.

Sounds like the setup load or save function is bugged again.

One has to really wonder how they keep bringing the same bugs back in, repeatedly, game after game…

like, how? Surely they have some form of git like workflow…

They probably have the backlog from hell and view it in LIFO order. Nobody is going to scroll down more than a few hundred rows. After that the bugs will probably be old enough that the team will have to reproduce them to validate they still apply. Too much hassle when there is already a heap of break-fix work on core and/or current features. Down there in the bug sump is where the life sentence bugs reside.

Probably. Still insane to repeatedly keep fixing the same thing game in game out.

Yes I am pretty sure they had this before…sucks as what tunes are proper and what tubes did people share that are nothing like they thought?
I have a few favorites I download from and how much better could they be?
Even the good tuners may have missed this so they may not be sharing the tune they thought they were and may not be of thier normal quality.
I shared about 15 tunes mostly singles but a few doubles ( grip and speed for a single car ) so which one is right and which one is not as good as it should be??? I guess what ever tune I adjusted last is the correct one and the one I thought I had done already is now a clone of the last one adjusted.

This explains a lot for me. I had made a grip tune for NASCAR races at road courses, only to find that it had all the values for my Daytona tune when I installed it. The give away was the gear ratios. felt way off. I checked my setup and sure enough, my grip tune was the oval setup…Charles

Maybe that’s why they haven’t fixed the aspiration glitch, 8 years and counting.

I thought this was addressed in forza 5? Am I missing something, this cant be in fm7 as well

It seems that it loads the saved build but keeps your current tune, if you want to load one of your previous saves correctly you have to do it before you enter the race menu. Not sure if this issue occurs when you load a downloaded setup. Will have to try next time n see what happens.
Working as intended lol

For years i do this, and it seems to work fine on FM7.

Lots of people have 1 fav car and loads of tunes for it and they switch around.
At this point i understand this dont work at this moment?

When i make a setup, i split it 3 tunes.

  1. Low aero (speed)
  2. medium aero (allround)
  3. high aero (grip)

Then i buy 3 cars, paint them and give every car its own tune.
I remember by paint jobs and switching cars is way faster the changing/loading tunes.

So a workaround for this problem seems to be to buy a car for each setup/tune you make.

That’s a great idea…however, all your car tunes for a certain type of car are not only for that car but rather for any car of that make, model, year. 3 tunes and 3 65 Ford Mustangs…
Any one of those 3 tunes are available on any of the 3 cars.
Every time you take a car into test drive it knows there are 3 tunes available for that car and any adjustments to better that tune changes all 3 or at least 2 ( I have not tried this with 3 tunes only 2 )
The tunes are not car specific, but specific to any car that the make, model and year of a car are the same

If you buy a 65 Ford Mustang and put 1 tune on it set up for grip and like it Great.
If you buy a 2nd 65 Ford Mustang to put make a speed tune for it, add more power parts and less handling parts. When you take it into test drive and make adjustments in the tuning ( air pressure ) those adjustments are made on that tune but " ALSO ON THE GRIP TUNE ALREADY MADE " changing a tune you don’t want changed.
They always give you the same tune with different parts installed…I dont think the parts change just the tune settings.

What he is suggesting is the work around that does work.
Being 3 separate cars for each tune, you arent swapping out tunes/builds, so the bug doesnt happen.

This is what most of us do anyway, but T10 introduced a new problem with the low garage count.
IE: if you do this for all your cars, you run out of room quickly. (I have no knowledge of what the car cap currently is).

I noticed some weirdness when I was switching back and forth between tunes. I’d load a different build for the same car and it would either keep the same tune or revert back to the default tune settings. What I noticed was that when I loaded the build from the tune settings instead of the parts selection, it would load the tune settings I had saved for that build.

When I get home I’ll double check my saved builds. But I’m 99% sure that the tune setting save properly on each build, but they don’t load properly, giving the appearance that it changes the tune settings for all of your builds.

After saving a distinct and different tune setting on a build, load one that you know is different from the upgrade interface, then go to the tune interface and load it again and see if you get the tune you originally saved for that build.

I did this with a car I didn’t do anything with yet… I made 2 tunes,
One titled 27 with 27 PSI in the tires
One titled 25 with 25 PSI in the tires
Went into test drive and loaded the 27 tune…changed the PSI to 30 backed out and loaded the 25 tune and it also had 30 PSI…it should have been at 25 yet as I had not changed anything on that tune yet.

If you select My tunes in freeplay then your build will load but the tuning settings will be default. Now to get around this you can either select tune and then press select on your controller and load tune. The other option is on the main screen and load tune in the upgrade/tune section. If racing online then make sure to load tune before you enter the lobby. If you have more than 1 tune for that car then you will need to purchase more cars!

This bug is a real pain.

I’ve done testing on this since prerelease and have since noted things in my head.

When loading a tune from the prerace tuning or uprade shop menus, there is a bug where tunes load incompletely, reverting all tuned settings to default.
When loading a tune from the tuning menu in Test Drive, there is a bug where the tunes load incompletely and utilises the last applied setting.

Saving works fine. It does not overwrite the files that you don’t intend to do so. It saves like in FM6. Problem lies when you load tunes in the situations in the paragraph above.

The results of testing showed saving to be normal. When you load the tunes in the main menu of the game, you would see two different tunes despite seeing duplicates in test drive. Before testing, I also assumed that saving was glitched and that it overwrote all preceding tunes. It does not. It is in fact a bug in the loading process.

No. You do not need multiple cars to have different tunes. Your tunes will save just like before. HOWEVER, you will need to load tunes from the main menu to load them correctly.

I’ve made a list of bugs and anecdotes in a WIP thread in the support section. However no one has read it let alone add to it.

Soldier2DEnd,
I have tried and confirmed your work around does work for me. I knew something was happening but I could not figure where it was going wrong. Every tine I though I had it figured out seems I would be thrown a curve ball and left scratching my head…LOL

***** BIG THANKS to all who helped with this by responses! And yes Dust, TGT Box, and PPS IVORBIGON we do not need a car for each tune but it probably works as well though.
