Dyno Tuning Preparation Checklist
How do I prepare my car for a Dyno Tuneup?

  1. Car Readiness

    • Ensure the vehicle is fully prepared for tuning with all issues resolved beforehand.

    • Check fan functionality, wiring, and absence of excessive smoke or fluid leaks.

    • Ensure proper bleeding of the cooling system.

  2. Mechanical/Electrical Repairs

    • Address any mechanical or electrical issues prior to the tuning session.

    • Minor problems may be addressed during tuning, but additional charges may apply.

  3. Attendance and Guests

    • Only the car owner should be present during the Dyno session.

    • Limit the number of attendees to avoid distractions.

    • Avoid bringing non-car enthusiasts as they may find the process tedious.

  4. Interior Preparation

    • Clear passenger seat/floor space for technician equipment.

    • Ensure accessibility to the Engine Control Unit (ECU).

  5. Cleanup Responsibility

    • Avoid spillage of fluids to prevent cleanup fees.

  6. Tool Usage

    • Obtain permission before using shop tools or equipment.

  7. Tire and Pressure Check

    • Maintain proper tire pressure (30-40psi) for optimal Dyno performance.

    • Use appropriate street tires; consult if drag radials are necessary.

  8. Fuel System

    • Replace fuel filter if mileage exceeds 30,000 miles.

    • Arrive with at least half a tank of gas for tuning.

    • Avoid mixing different octane fuels unless discussed prior.

  9. Clutch Condition

    • Ensure clutch is not slipping and properly adjusted.

    • Confirm minimal free play in clutch pedal.

  10. Check Engine Lights

    • Address any check engine codes before the tuning session.

    • Critical codes affecting performance must be resolved prior to tuning.

  11. Ignition System Health

    • Resolve ignition problems such as misfires before tuning.

    • Tune-related misfires may be addressed during the session.

  12. Compression Test

    • Verify engine compression and cylinder uniformity.

  13. Boost/Vacuum Leaks

    • Check for and fix any boost leaks prior to tuning.

  14. Timing Components

    • Ensure correct timing belt alignment and functionality.

    • Timing covers and crank pulleys must be present for timing adjustments.

  15. Spark Plugs

    • Use appropriate heat range and gap for the application.

    • Bring extra plugs for easy replacement if necessary.

  16. Fluid Levels

    • Maintain proper oil and coolant levels; address leaks beforehand.

  17. Cooling System

    • Ensure the cooling system is fully operational with functioning fans.

    • Install a thermostat for consistent performance.

  18. Battery/Alternator Health

    • Confirm battery strength and alternator output to prevent electrical issues.

  19. Wiring Integrity

    • Solder connections securely; avoid exposed wiring.

    • Ensure proper voltage to critical components like the fuel pump.

  20. Exhaust System

    • Repair any exhaust leaks to avoid performance issues.

    • Ensure compatibility for wideband O2 sensor installation if required.
