Aim Taipan Y V2 ECU

The Taipan Y V2 ECU is an aftermarket plug & play engine control unit created by Aim, exclusively designed for plug & play installation with Yamaha YZ250F and YZ450F motocross bikes (2024-2025).

 Why Choose theTaipan Y V2 ECU

Thanks to its high-technology 32-bit core, the Taipan Y V2 ECU represents an important step forward to improve the performance of your motocross bike, without sacrificing reliability and smoothness.

Engine control requires precision. At 20,000 RPM, the Taipan Y V2 ECU guarantees precision of 1/10 of a degree: this means an accuracy within 0.8 microseconds (µs) for turning the spark ON.

This precision is the key to guarantee:

  • A very consistent engine rotation.
  • The possibility of repeating dozens of tests at the bench, always obtaining the same result.
  • A perfect reactivity at every minimum change of any point of a map, resulting in more power at the wheel.

Taipan Y V2 ECU Key Features & Strategies

The Taipan ECU can manage up to 5 maps that can be selected both by OEM switches or even more easily by the Aim Handlebar Switch 2.

The possibility to configure and set your motocross bike, thanks to the many different strategies and corrections implemented by the Taipan Y V2 ECU, is endless. Here’s a list of the most important:

  • Injection main alpha-n
  • Injection main speed-density
  • Injection crank correction
  • Pre-injection
  • Injection BAP correction
  • Injection EWT correction
  • Injection IAT correction
  • Injector battery correction
  • Injector 2
  • Ignition BAP correction
  • Ignition EWT correction
  • Ignition IAT correction
  • Ignition opening transient correction
  • Ignition closing transient correction
  • Launch control
  • Injection launch control main table
  • Ignition launch control main table
  • Quick shift
  • Traction control

Traction Control Strategy

For each map, the ECU has a dedicated traction control main table.

Launch Control

For each map, the ECU has a dedicated launch control main table.

UC Bridge & UC Bridge Tuner

The UC Bridge is the connection between the CAN bus of the ECU and the USB port of your PC.

Once the unprogrammed Taipan Y V2 ECU has been configured with a dedicated brand or model, it cannot be changed. You will be able to modify the maps written into the ECU, but the brand or model which has been configured cannot be changed.

Our leading motocross ECU provides the ultimate control in ignition, ignition phase, start maps, launch control, traction control with altitude, and engine temperature corrections.

The UC Bridge is the perfect solution for riders who want simple, reliable ECU management. With it, you can easily flash maps from your tuner, monitor ECU status, and make basic adjustments like fuel injection corrections – all without the complexity of advanced tuning.

For tuners, the UC Bridge Tuner takes things to the next level. It unlocks full control over map creation, modification, and ECU configuration, giving tuners the flexibility to deliver completely customised performance setups.

Taipan Y V2 ECU Connections

The Taipan Y V2 ECU has 4 connectors:

  • Main Connector: Compatible with most off-road bikes.
  • CAN Connector: Connects to the Handlebar Switch 2 and data logger.
  • 2nd CAN Connector: Connects to the UC Bridge to communicate with the PC.
  • 3rd Connector: Connects to spare analogue inputs and a possible second injector.

Handlebar Switch 2

The Aim Handlebar Switch 2 is the best way to change the behaviour of your motocross bike. It features 4 push buttons, 11 integrated LEDs, and manages the following settings:

  • Up to 5 selectable maps
  • Apply fuel corrections
  • Activate traction control
  • Activate launch control

The Handlebar Switch 2 can also be used as a shift light module.
