Jason Gaunt / Mbed 2 deprecated EFI-Engine-Simulator

A small lightweight program to simulate cam and crank engine signals for ECU / PCM testing

Dependencies:   mbed

The purpose of this program is to simulate the CPS (Crank Position Sensor) and the CAS (Crank Angle Sensor) of a "traditional" 4-stroke engine for testing Electronic Fuel Injection engine computers (aka the EFI ECU or PCM).

Initially this project will be used to simulate one of the following engines, but it's hoped that this will expand over time - if you want to help, email me.

• Mitsubishi 6G72 DOHC - Used in the GTO / 3000GT and Dodge Stealth equivalent
• Mitsubishi 6A13 DOHC - Used in the 8th Gen Galant VR-4 / Legnum

Both of these cars use a hall-effect 3-vane CPS and 4-vane CAS, details can be found here; http://www.stealth316.com/2-ignitionsystem.htm

Let's give a little back to the community, even if it's just a few bucks :)
