EAC Flash Tune – CARB Legal Performance ECUTEK Tuning Package for VQ37VHR

EAC Flash Tune - CARB APPROVAL PENDING

EPA & CARB Legal Performance Tuning for 3.7L VQ Engines
By Enthusiast Auto Care (EAC)

🧠 Why This Is More Than Just a Tune

The EAC Flash Tune is a personalized, open-style tuning experience built around your specific vehicle—not a preloaded map or off-the-shelf solution.

Every calibration is developed using real data collected directly from your car. Through detailed logging, analysis, and hands-on optimization, I tailor the tune to exactly how your engine behaves—ensuring it performs as it should in the real world.

Although the process is custom to each vehicle, this customization is engineered specifically to ensure full compliance with emissions standards. Every adjustment is made with the same level of precision used during laboratory testing, so that the final product reflects the configuration submitted and certified for EPA and CARB emissions compliance.

This is the magic of the EAC approach: your car, your data, your custom calibration—built to perform and comply.

Other options may look cheaper upfront, but they can’t compete with the level of detail, support, and integrity this tuning process delivers.

⚡ 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.

💥 Real-World Examples

• Gain 5–10% or more wheel horsepower, even on 91 octane
• A vehicle making 300 whp can reach 330+ whp with the tune
• Improved throttle response and stronger midrange torque

🧬 Automatic Octane Adaptation

This calibration dynamically adjusts for any fuel between 87–93 octane, modifying timing and knock control in real-time. No switching maps, no hassle—just consistent power on whatever fuel you run.

⚙️ 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 are not designed to retune for every modification but rather to ensure your car is running exactly as it should. I fine-tune fuel trims, throttle feel, knock sensitivity, and more—until it’s perfect.

🧰 Mod-Friendly by Design

This tune is written to automatically adapt to most common bolt-on modifications:

• Intakes, exhaust systems, headers, and throttle body upgrades
• Fuel blend changes (E10 pump gas, winter blends, etc.)

Have a question about your setup? Call me directly. I’ll confirm compatibility and guide you through anything custom.

🚫 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

• Fully legal – EPA & CARB compliant
• 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.
