Add FSD to a Acura TLX? Here's what works
Tesla's FSD stays on Teslas. But your TLX can steer itself and follow traffic with one device plugged in behind the mirror.
Yes. Your TLX is on comma's list.
comma lists the 2021–2025 TLX. Every trim qualifies. The car's own adaptive cruise keeps speed control; an early openpilot option exists. Steering works all the way down to a stop.
Steers itself in the lane
Continuous centring on highways and most roads, not a nudge back from the line.
Follows the car ahead
Your car's adaptive cruise keeps doing the gas and brakes while openpilot steers.
You stay in charge
A driver camera checks your eyes. No city turns, no naps, no FSD claims.
How to add it to your TLX
Four steps. No wiring cut, no dealer visit.
- 1
Confirm your year and trim
Open your exact TLX below. Trim names decide whether the car has the cruise and camera openpilot needs.
- 2
Order the comma four with the matching car harness
Pick your car in comma's shop and the right harness is added. Nothing else is required.
- 3
Mount it behind the mirror
Stick the mount high and centred, plug the harness in at the camera, and route one cable. About fifteen minutes.
- 4
Drive a few minutes, then engage
It calibrates on your first drive. Then press your cruise button and the TLX takes the lane.
What the first drive is like
Every TLX comma lists
Open your year for the exact trim, harness, and what controls speed.
AcuraWatch versus openpilot
AcuraWatch centres the lane above about 45 mph and needs your hands on the wheel. openpilot keeps centring at every speed, with a camera watching your eyes instead.
Questions TLX owners ask
Is this Tesla FSD for a TLX?
No. FSD is Tesla software for Tesla cars. This is openpilot, an open-source driver-assist system that steers and follows traffic on your TLX. You watch the road and stay responsible.
Which Acura TLX years work?
comma lists the 2021–2025 TLX. Open the exact year below to confirm your trim.
Do I keep AcuraWatch?
Yes. The harness sits between the car and its camera, and your factory safety features keep working. Unplug it and the car is stock again.
Does it handle stop-and-go traffic?
Yes on the listed TLX years. It slows to a stop behind traffic and moves off again on its own.
Is there a subscription?
No. The device and the software are a one-time purchase. comma prime is an optional extra for remote access and longer drive storage.
Do I need to keep my hands on the wheel?
Not constantly. A small camera watches that your eyes stay on the road, and openpilot warns you and stops steering if they do not.
