7073 Micro Cam-Sync

EFI systems trigger coils in two ways, wasted spark and sequential

The term "wasted spark" refers to two cylinders firing the spark plug at the same time when only one spark per cylinder is needed

On VW engines, #1 and #3 spark plugs will fire together and #2 and #4 will fire together

Wasted spark is the most common way of triggering ignition coil/coils on most EFI applications

The term" Sequential" refers to cylinders firing once every 180 degrees of crankshaft rotation based on the firing order of the engine

When triggering coils in Sequential, precise ignition timing is achieved by the trimming of each cylinders spark timing, allowing for 100% accuracy throughout the engines rpm range

Sequential spark requires the EFI ECU to know where #1 cylinder is in the firing order of the engine

The use of a cam sync is the easiest way of accomplishing this task

The cam sync replaces the distributor, triggering the EFI ECU when #1 cylinder is reached in the firing order

The ECU then fires each coil individually based on the firing order of the engine

The CB performance Micro Cam Sync uses a Hall output and does not incorporate a pull up resistor

If your ECU requires a pull up resistor, please contact the manufacturer about adding one to your system

ONLY the CB Performance Gen-4 ECU allows for a hall cam input.***Not compatible with previous versions of CB's EFI.***USES #7150 ConnectorWiring -Red - Switched Power 5v up to 16vBlack - GroundBlue - Signal to ECU
