Digital ignition system for a car.

Status: Done, depricated.

A replacement ignition system, for older cars with mecanical ignition system, for dynamicly changing the ignition angle depending on the RPM.

A controller, PIC16F877, is messuring time between pulses from a HAL-sensor placed at the motor's axis and calculates the RPM. Depending on the RPM, it waits a certain amount of time before it creates a pulse out to a MOSFET ignitioning the ignintion coil.

In a four cylinder engine, two MOSFET's are needed.

PC software written in Visual Basic 6 for realtime changeing and saving delay time for quantified RPM levels. Also able to view current RPM.

N/A

The firmware is written in HI-TECH PICC using MPLAB.
