Complete Control Package: Elite 2500 & Harness for JZX100
The Elite 2500 + Toyota Chaser JZX100 Plug ‘n’ Play Adaptor Harness Kit is the all-in-one solution for 1JZ-GTE VVT-i owners seeking top-tier engine management. This bundle combines the flagship Elite 2500 ECU with a vehicle-specific adaptor harness, providing immediate access to advanced motorsport features like Drive-By-Wire (DBW) control, knock protection, and flex-fuel capability. Designed specifically for the JZX100 Chaser, Mark II, Cresta, and JZZ30 Soarer, this kit replaces the restrictive factory ECU, allowing for precise tuning of the variable valve timing and sequential turbo system (or single turbo conversions).
Engineering for the 1JZ VVT-i
The Elite 2500 is uniquely suited for the 1JZ VVT-i due to its advanced DBW support. Unlike lesser ECUs, the Elite 2500 can fully control the factory ETCS-i throttle body, enabling features like idle control, traction control strategies, and rev-matching (where applicable). The adaptor harness correctly maps the engine’s reluctor triggers and cam sensors to the Elite 2500, ensuring rock-solid ignition timing at any RPM. It also breaks out auxiliary inputs/outputs via a separate connector, allowing for the easy addition of a wideband controller, boost trim switch, or fuel pressure sensor.
Operational Benefits
This kit simplifies the path to high horsepower. By removing the factory ECU, you eliminate the fuel cut and speed limiters that hinder performance. The Elite 2500’s long-term learning capabilities ensure the engine runs optimally in all conditions. While the factory Traction Control (TRC) and Snow Mode systems are disabled (as they rely on the stock ECU), the Elite 2500 offers its own superior, motorsport-grade traction control strategies that can be configured by the tuner.
