Supported Engines

This module is essential for tuning some of the most popular V6 engines in the Toyota/Lexus lineup:

• 2GR-FE / 2GR-FSE: The 3.5L V6 found in the Camry, Avalon, RAV4, Lexus IS350, GS350, and RX350.

• 3MZ-FE: The 3.3L V6 used in the Highlander, Sienna, and Lexus RX330/ES330.

• 2JZ-GE: The legendary 3.0L inline-6 (VVTi versions found in the Lexus IS300 and GS300).

Comprehensive Tuning Maps

The module grants access to critical parameters for both engine performance and transmission behavior:

Engine Performance & Airflow

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

• VVT Control: Intake and exhaust camshaft positions for all load ranges (Base, Low/High Throttle, Full Load).

• Throttle Valve: Comprehensive control including maximal allowed positions per gear (1st, Reverse) and position limitations based on Secondary Air Pump (SAP) faults.

• Torque Model: Optimal torque maps for both the engine and transmission coordination.

Ignition & Fueling

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

• Knock Management: Detailed retardation limits, recovery rates, and temperature-based knock thresholds.

• Fuel Enrichment: Injection time correction factors, injector dead time, and startup fuel adders.

Automatic Transmission Logic

• Shift Points: Upshift and downshift conditions defined by Output Speed vs. Throttle.

• Torque Converter: Detailed apply/release maps for Normal and Sport modes, including "Flex" control logic and the "Toyota Temporary Curve."

• Hot Mode Management: Oil and coolant temperature thresholds to enable/disable transmission protection modes.

Safety & Diagnostics

• Limiters: Engine speed (RPM) and Vehicle speed (Vmax) limits.

• DTC Mask Editor: Allows for the removal of specific Diagnostic Trouble Codes (e.g., for off-road or modified vehicles).
