Ok so in all of my time on Forza I’ve never really dabbled with the tuning mode beyond Diff and gearing settings, but today after looking for an E36 tune on FH3, I couldn’t seem to find anything that I could use that had the specific aesthetic upgrades I was hoping for. So I decided to try and make a proper tune for it myself.
Now I spent a few hours on it both learning and tunning all the settings before I had something I thought was good. But I need to ask about a behavior of the car that has always been something I could never figure out when it comes to RWD. How do you suppress the rear wheels from kicking out when accelerating out of a corner? Not under full throttle of course, but I have always used other people’s RWD tunes and they seem to have this behavior mostly in line. I tried a few things, mainly lowering the bump stiffness, increasing rear ride height, as well as the accel diff setting down lower to let the wheels slip more, which helped a fair bit, but the car still seems to have that tendency to kick out and I’m out of ideas on what to do next.
If I’m not really making sense, I shared the E36 tune for downloading. Search my gamertag or search “North City Circuit” in the description so you can find it. I would love any feedback on the tune as well if anyone has any to offer.
there are plenty of guides on how to tune from these forums and on youtube. if you are trying to build a car with certain aesthetic upgrades i assume you just mean wheels? otherwise you may be limiting your cars “max potential” i’ll download the tune and test it
Really? I was sure I posted it. I’ll go check again.
EDIT: It’s definitely shared. Try looking up S1 class, keyword 1 ‘Circuit’, keyword 2 ‘Expert’. It should be one of only two tunes found. If not then, maybe it takes time to show up on the storefront? I wouldn’t know lol.
It’s the 1997 E36 m3 (midnight battle one) in S1.
When I mean aesthetics I refer to the widebody with the forza aero, and specific rims. Reason for it is the race-spec E36 M3 GTR’s looked a lot like this and I’m a big fan of them. I never intended to bring out all the potential in it because then it wouldn’t feel like the car I’m aspiring towards.
As far as guides, they have helped, and I do feel like I have it mostly figured out on what everything does, except only when taming that tail-happy behaviour. No matter what I’ve tried, I just can’t seem to get it right, even tho I’m doing my best to follow along. :S
Try giving the springs some stiffness along with the ARB’s as well. (Rear stiffer than the front). Add a little toe out to ur front wheels (0.2-0.3) so your front wheels are constantly moving inward.
Consider wider rear tires
Consider various roll cages
Idk what options are available for the car but generally those two upgrades will help with rear wheel spin. BMWs are normally pretty loose and a reinforced chassis helps. Wider rear tires may help but if they are too wide you may have issues with the rear end sticking so well that car is no longer able to turn in as good. I had this issue with a NSX yesterday.
Tune:
Lower rear ride height. With a mega power no aero tune higher rear ride height (to an extent) helps with corner stability. Once you put forza aero on though, that benefit goes away.
From there it’s depends on if rear spin is caused by a loose chassis or a traction issue. If it’s traction related and build modifications don’t work, you’ll be tinkering a bit. Given that it’s a BMW you’ll probably need to tune the gears. It always seems those cars are twitchy when shifting from 2nd to 3rd. Try the standard 40/20 diff setting. Seems to work pretty well on some rwd I’ve tried.
Good recommendations Swerve. I am still getting the hang of the switch from Motorsport. Think I’m getting it down. Felix, I’d certainly give these a shot. Also keep in mind this Horizon business is very drifty by design. Throttle control is always a big factor. Just a smidgen of gas in spots, lol.
First, I think it’s important to do all tuning with assists off, so that’s how I drove your car. If you used traction control, you likely had a very different experience than me. But it’s fairly impossible to tell what’s wrong with a car when using assists.
IMO, the M3 just isn’t a viable car for an S1 RWD build. It has too much HP. You might be able to make it a little more driveable by lengthening the gears. First and second in particular are way too short. Maybe set accel differential to zero, but I just don’t think you can get enough grip on S1. Some builds just can’t be forced in FH3.
I did a quick 10 minute build and 30 second test drive of an A class before coming to my nephew’s baseball game. I shared the tune if you want to check it out. I used manual w/clutch and turned off assists.
Sorry about the late reply. Thanks for everyone’s advice! It’s very helpful and I will definitely take it on board.
Again, I know the car is way out there in terms of the build, but that was just what I personally wanted out of the car, rather than focused on being quick using engine swaps and AWD etc. Next time I set out to build something like a proper leaderboard car, I will make sure I spare no expense in having the best potential out of the build. As far as tuning however, I will definitely try everyone’s ideas out as soon as I get the opportunity.
To build a little more context on what I did, I tuned using the rainforest area for some mid-level lapping with no assists. I figured the variable gradients of the roads there mixed with some tight and some fast corners would help me tune the car for more of an all-purpose setup. Is this a good area? Or is there any better spots anyone has in mind? My gearing I also actually changed first and second to be shorter because I found that the car can handle accelerating better (Yes, the same behaviour I started this thread about lol) when it’s low in 3rd gear, since it was staying out of the power band at low speeds, which doubled up with it then only really needing 3rd gear in mid to low speed turns. But I normally tune gears in a much smoother fashion, so it’s good to know that I should stick to that instead lol.
What really stands out to me however is the ideas to use toe out and lowering ride height. These things I was absolutely new to and I figured having the front toe bringing the backs of the tyres in would help it have better turn in, but I didn’t really know much better about it. On the other hand, with the ride height, having followed the advice on the tuning menu when I was stumped by the tail kicking out I raised the height to help fix it. What I didn’t know was that it doesn’t really work with Forza aero and that I should actually lower it instead. I guess I made my situation worse then? XD
In any case, I’m still very thankful for everyone’s advice. I’m easily the newbie here so I have a lot to learn. I may start making a hobby out of tuning now.
