Supported Engines

This module covers the flagship naturally aspirated V8 powerplants used in Lexus "F" models and Toyota's full-size trucks and SUVs:

• 2UR-GSE / 2UR-FSE: Found in the Lexus IS F, RC F, GS F, and LS600h.

• 3UR-FE / 3UR-FBE: Found in the Toyota Land Cruiser 200, Sequoia, and Tundra.

Comprehensive Map Categories

The module offers an extensive list of maps for professional-grade tuning:

Ignition and Knock Control

• Advance Maps: Spark advance base, base high/low octane, and delta for efficiency.

• Knock Logic: Retardation amount, recovery rate, total retardation limit, and coolant temperature thresholds for knock control.

• Minimal Spark: Base minimal advance and temperature-based corrections for engine protection.

Transmission and Torque Converter

• Shift Points: Upshift and downshift conditions (Output Speed vs. Throttle) across different driving modes.

• Torque Converter: Detailed control for apply/release in Normal and Sport modes, including "Flex" control and temporary curves.

• Fluid Management: Temperature thresholds (oil and coolant) to enable or disable "hot mode" logic.

Air, Fuel, and Torque Modeling

• Airflow: Mass air flow (MAF) sensor scaling and intake air temperature (IAT) correction factors.

• Fueling: Enrichment factors, injector dead time, and minimal injection time logic.

• Torque: Optimal torque maps and transmission-specific torque requests.

• VVT: Base and load-specific position maps for both intake and exhaust camshafts.

Limiters and Idle

• Limits: Engine speed (RPM) and Vehicle speed (Vmax) limitation.

• Idle: Desired idle speed in P/N or Drive, and idle-specific spark advance.

Supported Software (SW) Examples

The compatibility list includes hundreds of 89663 series software IDs. Key series include:

Technical Usage

• Software Requirement: Operates within the BitEdit tuning environment.

• Licensing: Requires a BitSoftware USB Security Dongle.

• Diagnostics: Includes a DTC Mask Editor to manage diagnostic trouble codes.
