About

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

Hardware

Development board 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.

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

Software

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

Schematics

N/A

Firmware

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