⚡ Performance Gains

The EAC Flash Tune delivers real-world, full-powerband gains—not just dyno peak numbers. It’s tuned to improve acceleration, throttle response, and drivability across all RPM ranges.

⚙️ Automatic Transmission Enhancements

For vehicles equipped with automatic transmissions, EAC’s custom torque models replace factory logic to improve shift quality, timing, and feel under load. Expect smoother, faster, and more consistent gear changes, especially during spirited driving or gear transitions under throttle.

🛡️ Engine Safety, Reinforced

• AFR Fail-Safe: Torque reduction during lean conditions to avoid detonation
• Coolant Overheat Fail-Safe: Torque limit triggers at 126°C to protect the engine
• Low Oil Temp Throttle Limit: Reduces stress during cold starts
• Enhanced Knock Detection: More active and sensitive than OEM, for better protection and adaptive response
• Launch Control: Included (manual transmission models only)
• Fully Adjustable Secondary Traction Control: Customizable for road, race, or weather conditions
• Includes Valet Mode and Anti-Theft Lockout

🧪 Already Tuned? I Can Still Help

Already running a tune from another shop or platform? I offer a free performance and safety analysis of your current calibration. Send in logs, and I’ll identify inefficiencies, gaps in knock control, AFR irregularities, or missed performance opportunities. You’ll know exactly what to expect if you switch to EAC Flash Tune.

🔁 Unlimited Revisions – Done Right

With EAC Flash Tune, you’re not limited to 1–3 updates like many tuners offer. I provide unlimited calibration revisions for up to 12 months.

These revisions are not designed to retune for every modification but rather to ensure your car is running exactly as it should.

🚫 Important Policy Note

All ECUTEK licenses, dongles, and tuning services are final sale. Due to their digital nature and licensing restrictions, no refunds can be issued.

🥇 Why Choose EAC Over Everyone Else

• Superior shift logic for automatics
• More usable power across the powerband than any competitor
• Enhanced safety features and real-time adaptation
• Unlimited revisions + direct, personal support

If you can find a competitor’s tune that performs better across the full powerband, I’ll personally review your logs and work with you until your calibration exceeds expectations. That’s the EAC Guarantee.
