Supported Engine Types

This module covers many of the most iconic and reliable Toyota powerplants:

• 1GR-FE: 4.0L V6 (Land Cruiser, Prado, 4Runner, FJ Cruiser, Tacoma)

• 2UZ-FE / 3UZ-FE: 4.7L and 4.3L V8 (Land Cruiser 100/200, Sequoia, Lexus LS430/GS430/SC430)

• 1UR-FE / 1UR-FSE: 4.6L V8 (Land Cruiser 200, Lexus LS460/GX460)

• 2GR-FXE: 3.5L/4.0L Hybrid variants

Key Tuning Parameters

The module provides a massive array of maps for granular control over engine and drivetrain behavior:

Engine Dynamics & Airflow

• Air Calculation: Calculated air load from requested torque and MAF pulsation factors.

• Sensor Scaling: Full MAF sensor scaling and intake air temperature correction factors.

• VVT: Intake and exhaust camshaft positions for base, low throttle, high throttle, and full load conditions.

• Throttle Control: Position limitations by gear (including 1st and Reverse), load-specific limitations, and requested throttle position.

Ignition & Knock Management

• Spark Advance: Base maps for high/low octane, idle-specific advance, and efficiency deltas.

• Knock Control: Retardation amounts, recovery rates, and total retardation limits.

• Protection: Coolant temperature thresholds for retardation and engine speed thresholds.

Transmission & Torque Converter

• Shift Logic: Upshift and downshift conditions (Output Speed vs. Throttle) for various driving modes.

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

• Fluid Logic: Temperature thresholds (oil and coolant) for "Hot Mode" engagement.

Fuel & Protection

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

• Thermal Protection: Exhaust temperature models (calculated and offset) for spark retardation and engine protection.

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

Supported Software (SW) Examples

The module supports an expansive list of software IDs. Key series include:

Usage Requirements
