PRODUCT DETAILS

MATCHED CALIBRATION SERVICE

Match the P01/P59 file to your actual LS setup.

Choose stock/mild, cam-swap or supported same-OS 4L80E segment preparation. DD84 reviews the original read and controller before delivery.

ECM-matched pre-built starting calibration for supported GM Gen III LS applications using P01 or P59 PCMs.

This is not a blind universal file. DD84 uses your original stock/read file, exact controller and operating-system information to match the base calibration to your application before delivery.

Choose your file

  • Stock / Mild Performance Base: basic bolt-on or swap startup calibration.
  • Cam Swap Base: starting calibration for a mechanically complete cammed LS combination.
  • 4L80E Segment-Swap Prep: for supported P01/P59 applications where a compatible transmission segment exists with the same exact OS ID.

Required after checkout

  • Year, make, model and VIN
  • Engine size and engine source
  • Transmission and gear/tire information
  • Fuel type and injector data

Installation — HP Tuners

  1. Install the current VCM Suite and connect a compatible HP Tuners interface.
  2. Before changing anything, read the vehicle and save the original file in a safe location.
  3. Open the DD84-delivered file and verify the intended VIN/controller/OS information against your order.
  4. Connect the vehicle to stable battery support, key ON / engine OFF, and close unnecessary electrical loads.
  5. When VCM Editor prompts for licensing, purchase/use the required HP Tuners credits for that vehicle/controller.
  6. Use the write method specified in the DD84 order instructions. Do not use Write Entire unless DD84 specifically instructs you to do so.
  7. After the write completes, cycle the ignition as instructed, scan for DTCs, start the vehicle, and perform a verification log before hard driving.

Segment swap instructions — same OS only

HP Tuners Segment Swapper requires the same exact OS ID in both files. If the OS IDs differ, stop and contact DD84.

  1. Open your base file in VCM Editor.
  2. Open the donor file as the Compare file.
  3. Go to Compare → Segment Swapper.
  4. Select only the segment(s) specified by DD84.
  5. Choose Import Selected Segments.
  6. Close Segment Swapper and save the new file under a new filename.
  7. Re-open the saved file and verify the intended segments before writing.

Not included: emissions-system defeat, mechanical repairs, dyno validation, HP Tuners credits, controller unlocks or hardware unless separately purchased.
