Mini Cam Sync V2 Tech

Mini Cam Sync V2 Installation Instructions (Preliminary)

  1. Prep the Mini Cam Sync V2
    Before installing the unit, install the hold-down clamp onto the Mini Cam Sync body.
    You may find it easier to temporarily remove the O-ring to do this. On some aluminum cases, the O-ring fit can be very tight. To help:
  • Soak the O-ring in very hot water for a few minutes to soften it
  • Apply a small amount of engine oil or grease during installation for a smoother fit
  1. Distributor Drive Gear Orientation
    The orientation of the distributor drive gear does not matter with the Mini Cam Sync V2.
    Most users will need to reinstall the gear — just make sure it’s back in place and don’t forget the two shims under the base.

  2. Set the Engine to TDC
    Rotate the engine to #1 Top Dead Center (TDC) on the compression stroke, using your pulley timing marks.

  3. Install the Trigger Wheel
    Apply a small amount of blue Loctite to the trigger wheel screw.
    Place the shim under the trigger wheel — setting it on the shaft first with a dab of grease can help hold it in place. Then align the indicator mark on the trigger wheel with the center of the Hall sensor pickup. You may need a few tries to get this spot-on.

  4. Set Up Your Trigger Wheel in the ECU
    Choose the trigger pattern that fits your setup:
  • 36-1 (Sequential Mode)
    • 36 teeth with 1 missing
    • Set offset angle to 60° BTDC
    • Supports full sequential spark and fuel at cam speed

  • 18-1 (Wasted Spark / Bank Fire)
    • Actually 36 teeth with 2 missing but the ECU sees 18-1 at crank speed equivalent
    • Set offset angle to 60° BTDC
    • Supports wasted spark and bank-fire injectors
    • Good for basic setups or retrofits
    • Faster Sync if you do not require sequential

  • Single Tooth (Cam Sync Only)
    • Provides a TDC reference only
    • Set offset angle to 180° BTDC
    • Must be paired with a crank trigger
    • Ideal for performance engines, as crank-based timing offers better precision
  1. Base Timing Setup (Static Timing)
    Disconnect your injectors or pull the fuel pump fuse, and lock your ECU timing to 10° BTDC.
    Crank the engine with a timing light and manually rotate the Mini Cam Sync body until you read 10° on the pulley. If you’re off by a lot, you can make small adjustments to the trigger wheel position to compensate.
    Once it’s dialed in, make sure to fully tighten the trigger wheel screw.

  2. Final Timing Calibration (Engine Running)
    Reconnect your coils and injectors, then start the engine.
    Use your ECU software to fine-tune the offset angle for precise spark timing.
    Also verify and adjust spark latency at higher RPM to compensate for any drift.
