IOCAN

# IOcan — Standalone Transmission Control Gateway

IOcan is a professional CAN gateway that makes modern OEM automatic and

dual-clutch transmissions — ZF 8HP, DCT/DKG, and PDK — usable outside of their

original vehicle environment. It recreates the CAN communication these

transmissions expect, so they run reliably in engine swaps, custom builds, and

motorsport applications.

## Key Capabilities

* Recreates the OEM CAN environment a standalone transmission expects

* Four independent CAN-FD interfaces with switchable 120 Ω termination

* Flexible driver input: sequential, paddle, OEM selector, or CAN keypad

* Integrated semiconductor relay for transmission power and wake-up — no external relays

* Permanent battery connection via a single fused supply (five vehicle connections total)

* Transmission current measurement for monitoring and diagnostics

* Diagnostic access and custom TCU flashing for supported 8HP units

## Typical Applications

* Engine swaps using modern automatic or DCT transmissions

* Custom vehicle builds and restomods

* Motorsport and track vehicles

* Transmission retrofits into non-original chassis

* Development, testing, and reverse-engineering projects
