Starting a new project with rusEFI to power a Ford Mustang V8 using the microRusEFI....will be adding details and such as things get underway...

The reason for the swap from the stock A9L is I have been dealing with a No Spark condition with the card over the last two years, spend a good chunk of money trying to get the car running and have decided that there is a gremlin in the main harness / ECU / ignition, so I had two choices

1 - re-wire the car with a stock OEM-type harness, re-write the ignition and then see where I am at....

2- use a rusEFI to get the car running and be a test mule

As the car is not a show queen, will never be one, it is just something to have fun with and make passes at the drag strip, I went with option 2...

Stay Tuned...

Just add a couple of wires and you are running!

Injector wiring would be a bit weird here. Here's the deal:

1) microRusEFI by itself is totally not a v8 ecu
2) you want all your injectors to be controlled by similar transistors so that your injectors all behave the same.

Solution? All your injectors would be controlled via auxiliary outputs, not default injector outputs.

On the adapter board you have U2 U3 chips - each of these is a dual-channel, so between U2 and U3 you control 4 injectors. On your microRusEFI 0.5.1 you would have two more of these auxiliary chips, that would be another four channels.

In the end here are the channels you use for injectors:
GPIOA_15: "AUX J2 PA15"
GPIOB_8: "AUX J2 PB8"
GPIOB_9: "AUX J2 PB9"
GPIOC_12: "AUX J2 PC12"
GPIOB_0: "AUX AV8 reuse"
GPIOB_1: "AUX AV9 reuse"
GPIOA_4: "AUX AV10 reuse"
GPIOC_4: "AUX AV6 reuse"

All of these are available in the "injector pin" drop down with microRusEFI project.

I assume that's the TFI ignition system? Distributor with vanes and a hall sensor? No crank sensor?
