Details

Performance Highlights

• Massive Power Gains: Safely unlock substantial horsepower and torque increases while maintaining OEM-level reliability and drivability.
• Multiple Fuel Maps: Includes 91, 93, and E85 calibrations (95/98 RON equivalent), allowing you to choose the fuel that best matches your goals.
• At-Home Flashing: Install, update, or change octane files directly from your smartphone using the POWERlink™ Bluetooth OBD-II interface.
• Brake Boost Enabled: Build boost while stationary or during roll racing for harder launches and improved acceleration.
• 7200 RPM Rev Limit: Extends the usable powerband and unlocks additional top-end power when paired with the matching IE ZF8 Transmission Tune.
• Optimized Cooling Strategy: Revised coolant pump control reduces heat soak between pulls and improves intercooler efficiency for more consistent performance.

Stage Guide

• Stage 1: Designed for completely stock vehicles or basic bolt-on upgrades such as an intake, heat exchanger, or catback exhaust. Delivers substantial horsepower and torque gains with no required hardware.
• Stage 2 Single Pulley: Calibrated specifically for vehicles equipped with a 57.5mm supercharger pulley. Increased boost pressure delivers dramatically improved performance while maintaining factory drivability.

Transmission Tune Recommended

Integrated Engineering strongly recommends pairing this ECU Tune with the matching IE ZF8 AL551 TCU Tune. The factory transmission upshifts around 6,300 RPM, while the ECU calibration continues producing power to 7,200 RPM. The TCU Tune unlocks the full powerband while also improving shift speed, launch control, torque management, and transmission responsiveness for the complete performance package.

E85 Flexibility

E85 fuel delivers the highest performance potential on the CREC 3.0T platform. IE's E85 calibration automatically compensates for ethanol content ranging from approximately E60 to E85, providing safe operation while maximizing horsepower and torque without requiring race fuel.
