Complete your automatic-to-manual transmission conversion with the Royal Tuned Pre-Tuned Manual Conversion ECU for the 2002–2005 Lexus GS300. Professionally calibrated and ready to install, this ECU is converted from a factory automatic ECU to support manual transmission applications with the Toyota 2JZ-GE VVT-i engine.

Each ECU comes pre-programmed with manual transmission support, a performance calibration, immobilizer removal, and a raised rev limiter, providing a convenient ECU solution without requiring additional ECU programming before installation.

Performance Calibration: Professionally calibrated to improve throttle response, drivability, and overall engine performance.

Manual Transmission Conversion: Converted from a factory automatic ECU and programmed specifically for vehicles that have been converted to a manual transmission.

Immobilizer Removal: Removes the factory immobilizer requirement, eliminating the need to match the replacement ECU to the original immobilizer and key programming.

Raised Rev Limiter: Factory rev limiter increased from approximately 6,700 RPM to 7,000 RPM.

Plug-and-Play ECU: Arrives pre-programmed and ready for installation with no additional ECU programming required for the included calibration.

Manual Swap Ready: Pre-programmed ECU helps simplify the electronic side of your automatic-to-manual transmission conversion.

Optional Exhaust Crackle Calibration: Optional calibration modifies engine behavior during deceleration to create a more pronounced exhaust crackle. Availability is subject to vehicle configuration and applicable emissions requirements.
