Outline
1
Process of Tuning
  • Prepare the vehicle (pre tuning checklist)
  • Tune the vehicle
  • Follow up and maintain the vehicle (post tuning checks)
2
Prepare the vehicle
  • Compression Test
  • Leak Down Test
  • Valve Adjustment
  • Check for leaks
  • Set Engine Timing
  • NO CHECK ENGINE LIGHTS!!!


3
Prepare the vehicle
  • Properly Working Electrical System
  • VTEC Functional (VTP, Oil Pressure)
  • Properly Equipped Fuel System
  • No wiring issues
  • Properly Working Ignition
  • Check Fluids
4
Tuning The Vehicle
  • Choose Basemap
    • Heavily dependant on Cam Profile
    • Dependant on Bore Size, Stroke & Comp
  • Set Injector Dead Times (Battery Offset)
  • Set Injector size (multipliers)
  • Start Car and adjust mult. & offset as well as basic idle
5
Tuning The Vehicle (cont.)
  • Smooth Lines (fuel and ign)
    • All should be perp and no crossing
  • Tune Columns Roughly
  • Tune Cell blocks Finely
  • Part throttle up to 0 psi (atmos. press.)
    • Fuel Targets
    • Ignition Targets
  • Low Cam and High Cam
6
Tuning The Vehicle (cont.)
  • Use built-in Calculators for Boost Tables
    • Start conservative, work to aggressive
  • Stepped vs. Linear Retard
  • Boost Compensation
  • MBT


7
Tuning The Vehicle (cont.)
  • Part Throttle Tricks
  • Race Gas Tuning
  • Water/Meth Injection
  • SET A BOOST CUT!!!
  • Cam Gear Adjustments
    • More overlap (high rpm/boost breathing)
      • Advance Intake, Retard Exhaust
    • Shift power-band up or down
8
Tuning The Vehicle (cont.)
  • Set Idle
    • Computer and Manual Adjustments
  • ECT Trims
    • Cool car completely and let warm
  • Post startup fuel delivery
    • 2-10 seconds depending on temp
  • Cranking fuel delivery
    • Crank at cold and full warm
9
Vehicle Maintenance
  • Regular Oil Changes
  • Check Fluids Weekly
  • Check and Change Plugs
  • Smoke Colors and what they mean
  • Vehicle Logging
  • Ignition Monitoring (Wires, Cap, Rotor)
