Next-Generation Engine Management with Automatic Transmission Support

ECUMaster has long been the go-to solution for Supra and 2JZ owners—especially with the proven EMU Black and WHP Plug-and-Play adapter lineup. Now, with the introduction of the EMU Pro, we’re unlocking powerful new capabilities for both street and motorsport builds, including factory automatic transmission support, advanced control strategies, and full vehicle integration.

Why Upgrade to EMU Pro?

Powerful Tools for Serious Tuners

With any ECUMaster EMU, you gain the flexibility to tune for:

• Higher boost levels

• Larger cams and injectors

• Nitrous and alternative fuels

• Aggressive turbo configurations

But EMU Pro goes further—with fully user-definable strategies that include:

• 2D, 3D, and 4D table mapping

• Custom functions and math channels

• User-defined CAN messages

• Built-in failsafes and logic conditions

Factory Automatic Transmission Support

A340 & A341 Integration – No Standalone TCU Required

EMU Pro offers full control of the factory A340 and A341 automatic transmissions directly within the EMU Pro Client software.

• Fully integrated with the OEM gear selector, including Overdrive and ECT buttons

• Supports custom shift logic, converter lockup control, and gear-dependent tuning strategies

• Transmission temperature and vehicle speed signals are built into the adapter harness

• Example base map includes Overdrive button configured as launch control trigger to showcase customization options

Manual transmission support is also fully included, with compatibility for both factory and aftermarket gearbox setups.

OEM Integration You Can Rely On

Plug-and-Play Features to Simplify Your Build

EMU Pro maintains support for critical factory systems to streamline your installation:

• Fuel Pump Control Module – No external controller needed

• Sequential Turbo System – Full control of OEM VSV solenoids for stock twin-turbo operation

• EVAP Solenoid Control – Prevents fuel vapor buildup and cabin odors

• A/C Compatibility – Retains OEM air conditioning operation for street comfort

The adapter harness comes pre-wired for the factory MAP and Intake Air Temp sensors to get you started quickly. For builds targeting higher boost, we recommend upgrading to a modern MAP + IAT combo. Our Wholesale Horsepower sensor kits are available from 3.5 to 7 BAR. The IAT sensor, originally housed in the MAF, can be relocated post-intercooler—simply extend the factory wires for a clean install without rewiring.

Logging, Mounting & Advanced Control Features

Built-In Tools for Data, Tuning, and Drivability

EMU Pro was designed to make tuning and integration just as seamless as installation.

• Log directly to your laptop via USB-to-CAN

• Or automate logging to a USB flash drive up to 32GB, using the built-in USB port on the adapter

• Optional mounting plate available for LHD JZA80 Supra—3D-scanned for a clean factory-style fit in the stock ECU location. (RHD version is currently in development)

For added performance, EMU Pro also eliminates the factory traction control system and replaces it with a fully customizable motorsports traction control strategy—using the OEM ABS wheel speed sensors.
Optional wiring instructions are included for seamless integration.

Backed by a Full Installation Manual

Built for Tuners and DIY Enthusiasts

All EMU Pro kits come with:

• Step-by-step installation instructions

• Pre-programmed base maps

• Wiring documentation for factory and optional upgrades

• Strategy notes and tuning guidance

Take Full Control of Your 2JZ

Whether you're keeping the factory automatic, swapping to a manual, or building a competitive drag-and-drive car, the EMU Pro gives you the tools and flexibility to optimize every aspect of your engine and transmission.
