Without the power distributor.

Advanced electronic controls significantly improve spark advance, eliminating the need for weights and centers. In fact, the engine management system completely eliminates the need for a distributor and therefore, the distributor cap! The distributor cap is a major issue in the lead up race cars with increasing distance from the spark plug and the secondary voltage. With higher voltages and spark plug, more flash, or against the shooting, more likely, especially between adjacent terminals in the distributor cap. And the terminal devices in the dispenser are even more so when your engine has eight cylinders.

When you remove the distributor, you need another system to generate a signal to the engine control unit (ECU) to know that each piston reaches top dead center (TDC). This can be achieved by adopting a sign of a pulse generator mounted on the crankshaft front pulley, or the steering wheel rim. The ECU can use this signal to determine the ignition timing and the firing angle of advance for each cylinder, and can change the low voltage primary circuit on and off at the right time.

The most important thing is without a distributor ignition system to ensure that the trigger pulse has been properly installed. This actually refers to three things you need to check: the diameter of the striker, the striker position, and the air gap.

THE FIRING PIN

Firing pins must be precisely positioned and has the correct diameter. It ‘clear that the precise timing of firing pins must be strictly in line with the magnetic pick-up, when each piston to TDC. To get a reliable signal, shoot at the pins must be the same diameter of a magnetic pickup. Using more or less axial magnetic pickup signals for the production of inaccurate and incorrect spark timing! The result could be catastrophic!

THE AIR GAP

Air space between the striker and the magnetic pickup will also be adapted to the distance specified by the manufacturer of Ignition distributor. Most manufacturers specify a gap of 0020-0040. “If the gap is too large, the signal is too weak and will lead to miss shooting and lack of power. If the gap is too small, the signal can be generated too early and your ignition timing also be outside.
