How to tune in Horizon?

So a quick background on me. I’ve been primarily a Forza Motorsports guy. I didn’t care for FH1 to FH3, but with the fecal matter show FM7 was, I decided to check out FH4. While never a top 3% guy in the FM tuning scene I had fairly competitive tunes and often would be in the top 10% or higher with non lap time cars.

Tuning in FH4 is completely foreign to me. Because you’re not just tuning for tracks you’re tuning for road and offroad racing with all that goes with it.

Is there any translation from the FM series that will apply to the FH series or do I need to relearn tuning all over again?

Thanks to anyone that can help. I can already see that the base tunes on cars is not optimal and needs tweaking to squeeze every bit of potential out of the cars, but not sure where to start.

At the end of the day this is a Forza title using Forza car physics, so similar tuning principles apply.

Where the Horizon games deviate is in the very different car builds required for Road, Dirt and Off-Road.

As you would expect, AWD conversions are almost mandatory for Dirt and Off-Road events and you should experiment with the new spring sets, wheel offsets and tyre compounds that the Horizon series offers to see which gives best results on each track. Get the build right and you are almost there.

One word: SOFT

As Moss said the street is pretty much the same. Anything off-road raise your ride height and play around with cutting your bump in half. If you’re using rally springs you’ll want to start by cutting those numbers in half compared to what you would use on a Forza race suspension. This won’t be perfect, but will give you a starting spot.

Something else to note. If you are in multiplayer there will be contact with other cars and immovable objects. Tune for acceleration. Different story if hotlapping. Also fastest way around a road race may involve some off road cuts. Light twitchy cars also get thrown off more when hitting objects, low cars struggle in water and deep snow.

The process of fixing understeer, oversteer etc is the same. As HLR moss said, experiment with the build.

Ability to directly compare subtle changes to tune / build is difficult without class based rivals though!

My question one if dumbest, but I for the life of me can’t remember what each value is in the power chart with 6 in the middle and 12 at the end, there’s only 11 lines across the graph, so they don’t are 1000rpm, and I’m to tired to try to the math that will honestly be futile…So someone, please take pitty on me fill me in… thanks
