Why customize CSS Electronics CANsub.2?
A physical CAN interface captures signals from a vehicle or test gauges for decoding. The CAN interface captures traffic; decoding and visualization run on a separate computer.
A good fit for
Capture CAN traffic. Decode real car and gauge signals with a custom CAN sniffer.
Not the right fit for
A guaranteed plug-and-play recreation without the listed hardware revisions, accessories and software setup.

Getting started
- 01
Check your model and revision
- 02
Read the creator’s setup
Use listen-only capture. Wiring and reference signals require expertise; decoded results are not safety-certified. Do not transmit control commands to a vehicle.
- 03
Start with a reversible test
Follow the linked project source before changing the device. Back up existing configuration, keep credentials private and stop if your hardware differs from the documented version.

Starter prompt
Help me plan decode real car and gauge signals with a custom can sniffer using CSS Electronics CANsub.2. Read https://www.csselectronics.com/pages/can-bus-reverse-engineering-ai-llm-claude and its supporting sources first. The CAN interface captures traffic; decoding and visualization run on a separate computer. Use listen-only capture. Wiring and reference signals require expertise; decoded results are not safety-certified. Do not transmit control commands to a vehicle. Confirm my exact hardware and required accessories, explain what is missing, and propose one reversible test. Ask before flashing firmware, changing privileged system settings or moving physical hardware.
Confirm your exact hardware before running device-changing commands.
