Tool support
Can we read
your car?
Search your car to see its usual ECU and how we read it with Autotuner and KESS3: through the diagnostic port, on the bench, or in boot mode.
AI label check
Have a photo of your ECU label?
Our AI reads the sticker on your ECU, tells you which ECU and car it is, how Autotuner and KESS3 read it, and your Stage 1 gains.
Get close, in good light, so the numbers are sharp. The photo is only used to read the label.

How we read it
Three ways in.
Your original software is backed up first, whichever way we connect.
- OBD
Diagnostic port
Read and written through the car's OBD socket. Nothing is removed from the car.
- Bench
On the bench
The ECU is taken out and connected on the bench. Newer locked ECUs need this, often only once.
- Boot
Boot mode
The ECU is opened and read through its boot connection, for ECUs that can't be read any other way.
Support list
The ECUs we read.
Typical support by ECU family. The exact hardware and software number decides, so we check yours with the tool before we start.
Not sure which ECU you have?
Send us a photo of the ECU label, or come in for a quick scan. We'll check it against the Autotuner and KESS3 lists and tell you how we'd read it.
