Installing the Cam Sync Drive
To realize the full benefits of the GEN3’s precise timing and individual cylinder fuel control, Top
Dead Center (TDC) for cylinder 1 (compression stroke) needs to be determined and marked on the
dampener. Rotate the engine to TDC, number 1 cylinder, compression (stroke). Install the cam sync
drive so that the gears on the drive and cam are engaged and the connector can be easily installed.
While applying pressure on the cam sync drive, turn the engine over until it fully engages with the cam
shaft. Tighten the cam sync drive clamp securely. Make the electrical connections to the cam sync
drive.
