SimHub with Assetto Corsa Competizione
Last updated · SimHub 9.11.22
Assetto Corsa Competizione publishes telemetry through shared memory and needs nothing enabled inside the game — SimHub reads it as soon as both are running. It is PC only, because shared memory cannot cross a network, so the console versions cannot feed SimHub at all. The usual cause of a problem is an administrator-rights mismatch, which fails silently. ACC has no mod scene, so it is one of the least troublesome sims to set up.
ACC is the straightforward one. If it does not work, there are only two realistic causes and both are below.
How it works
Shared memory, no in-game configuration. ACC publishes its telemetry structure whenever it runs.
Multiple applications can read it simultaneously, so running SimHub alongside a race engineer app or a lap timer causes no contention.
PC only, and this is not a policy decision. Shared memory is a local mechanism — it cannot cross a network. The PlayStation and Xbox versions of ACC have no way to send telemetry to a PC, and no workaround exists. This is the same reason Assetto Corsa, iRacing and rFactor 2 are PC only.
Setting it up
Enable ACC in SimHub
Tick it in the game list. Note it is a separate entry from Assetto Corsa — enabling one does not enable the other.
Check administrator rights match
If ACC or its launcher is elevated, SimHub must be too.

Values appear immediately. A practice session is enough.
ACC gotchas
- It is a separate game entry. People who already had Assetto Corsa working assume ACC is covered by the same tick. It is not.
- Administrator rights. The usual silent failure. Elevate both or neither.
- No mod scene, which removes the entire class of problems that affects Assetto Corsa. If ACC is not working, it is not because of something you installed into it.
- Console versions cannot work, and this is worth being clear about rather than hopeful — no setting, network configuration or third-party tool bridges shared memory off a console.
What works well here
ACC is GT3 and GT4 racing almost exclusively, which makes it unusually well suited to a fixed haptics setup — every car has broadly similar characteristics, so a profile tuned once works across the whole grid rather than needing per-car adjustment.
The same applies to shift lights. Because the cars are homogeneous, a percentage range set once is right nearly everywhere, and per-car calibration is worth less here than in a sim with a mixed field.
ACC also provides a rich telemetry set, so most effects have real data behind them. It is a good sim to build a haptics profile in and then adapt elsewhere.
Common questions
Do I need to enable telemetry in ACC?
No. Assetto Corsa Competizione publishes telemetry through shared memory whenever it runs, with no in-game setting to change. Ticking ACC in SimHub's game list is the only step.
Does SimHub work with ACC on PS5 or Xbox?
No. ACC uses shared memory, which is a local mechanism and cannot cross a network, so a console cannot send telemetry to a PC. This is not a policy choice and there is no workaround — unlike Gran Turismo 7 or the F1 series, which broadcast over UDP.
I have Assetto Corsa working — why not ACC?
They are separate entries in SimHub with separate settings. Enabling one does not enable the other. Tick ACC specifically in the game list.
Why does SimHub show no data in ACC?
Almost certainly an administrator-rights mismatch: if ACC or its launcher runs elevated, SimHub must too, because Windows will not let a normal process read an elevated one's memory. It fails with no error at all.
Do I need per-car shift light settings in ACC?
Less than in most sims. GT3 and GT4 cars are broadly similar, so a percentage-based range set once works across the grid. Per-car calibration pays off much more in a sim with a mixed field of very different cars.
Can I run SimHub and a race engineer app together in ACC?
Yes, with no configuration. Shared memory can be read by any number of applications simultaneously. The one-at-a-time contention problem only affects UDP games.
