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.

Documentation¶

Start here¶

• What is IOcan? — overview, capabilities, and intended use
• Supported Vehicles & Modules — engines, transmissions, shifters, dashboards, keypads, and aftermarket ECUs supported over CAN
• Supported Transmissions — current transmission support and status
• Getting Started with IOcan — first power-up, the five core connections, and initial validation

Specifications¶

• Hardware & Electrical Specifications — supply, CAN interfaces, inputs, outputs, connector, and power management

Installation & Wiring¶

• Wiring Concepts — system architecture, vehicle/transmission CAN separation, and power sequencing
• CAN Gateway Pinout — main connector and transmission/shifter pinouts (7DT45, 8HPxx, DKG, GWS, OBD)
• BMW F30 Gateway connection guide — worked vehicle integration example
• Land Rover Evoque Shifter — shifter integration reference

Configuration¶

• Configuration Concepts — how signals flow through the device: inputs, controllers, CAN presets, networks, and outputs

Diagnostics & Development¶

• Reading DTCs, adaptation values, and custom TCU flashing for supported 8HP applications (documentation in progress)

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
