Frequently Asked Questions

What

What is EFI Live AutoCal V3?

The EFI Live AutoCal V3 is a handheld pass-through device used for reading, flashing, and storing custom EFI Live tune files on supported GM and Cummins vehicles. It’s designed to give end-users the ability to load custom engine and transmission calibrations without needing the full EFI Live FlashScan hardware.

  • Key Features: Enhanced processors for faster flashing, built-in data logging capabilities, and an SD card slot for storing multiple tunes and logs.
What is an EFI Live EGR delete?

An EFI Live EGR delete refers to modifying an engine calibration (using EFI Live tune files) to disable or remove the functionality of the Exhaust Gas Recirculation (EGR) system electronically. This is typically done in conjunction with physical hardware changes on off-road or competition vehicles.

What do EFI Live tune files do for performance?
  • Performance Gains: Properly configured EFI Live tune files can improve throttle response, horsepower, torque, and fuel efficiency. They can also adjust transmission settings for better drivability.
  • Customization: Tuners can create files tailored to specific modifications (e.g., bigger turbo, upgraded injectors) or to remove/disable certain emissions components for off-road use.

How

How do I load EFI Live tune files onto my AutoCal V3?

You need EFILive Scan & Tune Software. Get all the tools and resources you need to optimize your truck below:

  1. Tune Files: Obtain custom EFI Live tune files from TunerDepot.com, your trusted source for professionally crafted EFI Live calibrations.
  2. Transfer Files: Connect the AutoCal V3 to your computer via USB and transfer the tune files into the device’s memory or SD card.
  3. Flash Vehicle: Plug the AutoCal V3 into your vehicle’s OBD-II port, follow on-screen prompts, and flash the desired tune to the ECM or TCM (Engine/Transmission Control Module).
How is an EFI Live EGR delete performed?
  1. Hardware Modification: For off-road vehicles, the EGR system is often physically removed or blocked.
  2. Tune Update: A custom EFI Live tune file is used to disable the EGR functionality within the ECM software.
How do I restore my vehicle to stock if needed?
  1. Stock File Backup: Your tuner should provide (or help you back up) the original factory calibration.
  2. Re-Flashing Process: Using the AutoCal V3, select the factory (stock) tune from your device’s memory and flash it back to your vehicle’s ECM/TCM.
  3. Importance: Retaining the stock file is crucial for diagnostics, warranty claims, and compliance checks.

When

When should I consider updating or changing my EFI Live tune files?
  • Vehicle Modifications: After installing performance parts like upgraded turbos, injectors, or intake/exhaust systems.
  • Drivability Issues: If you notice excessive smoke, rough idle or poor fuel economy.
  • Software Updates: When EFI Live releases firmware or software enhancements that improve performance or compatibility.
When is it appropriate to use an EFI Live EGR delete tune?

An EFI Live EGR delete tune is ideal when optimizing your vehicle for off-road or competition use, particularly if you remove the DPF or EGR components. By pairing these tunes with Tuners like the Efilive, H&S Mini Maxx or EZ Lynk Auto Agent 3, you’ll maintain smooth engine operation and gain performance benefits. All necessary DPF/EGR components, delete kits and tuners are available at TunerDepot.com.

When will I see results from my new EFI Live tune files?
  • Immediate Feedback: Most drivers notice improved throttle response, power output and fuel efficiency as soon as the tune is flashed.
  • Learning Period: The vehicle’s ECM may take a few drive cycles to adapt fully to the new calibration.
