Stop guessing at cam-swap problems. Collect the right data and separate calibration needs from mechanical faults.

The DD84 Cam Swap Scanner & Diagnostic Pack is a structured logging and review system for cammed GM LS applications. It helps organize idle, fuel, spark, airflow, wideband and misfire data before unnecessary tune revisions are made.

Best for

  • Cam-swap vehicles with unstable idle, stalling, surging or poor drivability
  • Remote-tuning customers who need a clear logging process
  • Technicians and tuners diagnosing fuel-trim, wideband, ignition or airflow concerns

What this pack helps you do

  • Select focused scanner channels for useful datalogs
  • Record cold start, warm idle, in-gear idle, cruise and deceleration consistently
  • Compare bank-to-bank fuel trims and misfire behavior
  • Check wideband validity before making fueling decisions
  • Separate airflow, fuel, spark, wiring, exhaust-leak and mechanical problems

Your digital package includes

  • Branded cam-swap scanner and diagnostic guide
  • Vehicle and modification intake workbook
  • Required and optional scanner-channel plan
  • Cold-start, warm-idle, in-gear idle, light-cruise and deceleration review sheets
  • Fuel-trim, wideband, knock, spark, airflow and misfire review workflow
  • Quick-start instructions and single-user license

Recommended workflow

  1. Complete the vehicle and modification intake.
  2. Verify mechanical condition, fuel pressure, wiring, exhaust integrity and wideband setup.
  3. Select the required scanner channels.
  4. Record each test using a clearly labeled tune revision and fuel type.
  5. Document the result and next action before requesting another revision.

Delivery and file formats

This is a digital ZIP package delivered electronically by Down Dirty 84 LLC after purchase. No physical product is shipped. Files include PDF and XLSX formats. A compatible PDF reader and spreadsheet application are required.

Important limitations

This pack is a diagnostic and logging workflow, not an automatic tune generator. It does not include a tune file, HP Tuners software, credits, licenses, controller unlocks, vehicle-specific calibration or emissions-defeat instructions.

Need the complete GM workflow? The DD84 GM Gen III/IV Professional Workflow Bundle combines this pack with the LS Swap Startup Toolkit and Transmission Calibration Calculator.
