Duramax Tuning Installation Guide: Step-by-Step Instructions

This guide provides step-by-step instructions for installing your Duramax tune. Please read and follow each step carefully to ensure optimal results. For advanced troubleshooting, submit a support ticket to PISTONTWISTIN@GMAIL.COM.

Vehicle Preparation:

  1. Close all vehicle doors.

  2. Disconnect all electronic accessories. It is crucial to keep doors closed and electronics off during the flashing process.

  3. Battery Health: Ensure your vehicle battery has sufficient voltage. A high-quality trickle charger is strongly recommended during flashing to prevent voltage spikes or drops that can damage the ECM, tuning device, or other electrical components.

  4. LB7/LLY Duramax Fuse Removal: For LB7 and LLY Duramax models, specific fuses may need to be removed before flashing to avoid errors. (Consult your specific instructions for fuse locations.)

Critical Warnings:

  • DO NOT unplug the tuning device (AutoCal/V2) while it is reading or flashing the vehicle. Unplugging during this process can cause serious damage.

Flashing Your Duramax Tune: Step-by-Step Guide

With your vehicle prepped, you're ready to flash the tune. Follow these instructions carefully:

  1. Connect the AutoCal: Plug the AutoCal device into your truck's OBD-II port using the provided cable.

  2. Key Position: Turn the ignition key to the "RUN" position without starting the engine.

  3. Select Tuning Tool: On the AutoCal screen, select "Tuning Tool" and confirm.

  4. Choose Tuning: Select "Tuning" and confirm.

  5. Program Full: Select "Program Full" and confirm.

  6. Select Tune File: Locate your tune file. DSP5 tunes are typically named "Mod_DSP5_ACL," while single tunes are named "Mod_XHP_ACL." Select your file and confirm.

  7. Warning & Licensing: Read the warning message and confirm. You'll then be prompted to license the ECU; confirm this as well.

  8. Flashing Process: The AutoCal will begin flashing the tune to your ECU. A progress bar will display the flashing progress.

  9. Completion & Ignition Off: Once the progress bar reaches 100%, a message will appear instructing you to turn the ignition off. Follow these instructions.

  10. Countdown & Disconnect: After turning the ignition off, confirm on the AutoCal. After the countdown, unplug the AutoCal from the OBD-II port.

  11. Start Your Engine: You can now start your truck.

  12. Monitor for Errors: Crucially, monitor the AutoCal for any error messages during the flashing process, even after 100% completion. Note down any error messages as you may need them for support.
