We might be able to trick the EDIS to think it was connected to a computer.
Ernest has a O-scoop so perhaps he can tell use what data the Megasquirt
must send to the EDIS.

I think the EDIS will limp home with a set advance. A computer is
suppose to send timing advance.

Thanks Blake. It is probably a digital signal sent serially.
Perhaps a PICAXE can do that job. If it is analog no problem.
Just feed it something 0 to 5 volts.

It is not difficult to do it properly:

The megasquirt is a good option.

We have one guy (Doc) working on a very simple low pressure EFI PICAXE
based system that PWM the fuel pump as the only fuel quantity control.
No high pressure injectors. No return flow. Easy to program in BASIC.
Built in USB computer interface on the PICAXE board.

I am working on an all mechanical low pressure system using a p-port slide throttle
as dual carbs more or less.

A lot of people have trouble with EFI as the knowledge required
is beyond most people.

We all need ignition.
