And - I've got the details on what we brought out of the connector on the back of the ECU, which is going to have 26 pins.
First, we've got all the extra spark outputs for a coil on plug conversion.
The boost control output is brought out to make it easier to wire up other types of solenoids.
We also brought out two outputs for a bank fired second stage of injectors. Whether you're drilling the manifold for twelve injectors or just have some extra injectors in the charge pipe, we can control them. These can also be used as general purpose on/off or PWM outputs for things like nitrous, fans, water injection, etc.
And we have three more general purpose outputs for similar uses.
For inputs, we have two inputs that can take a switched signal (including one flex fuel sensors) or frequency based signals, and two inputs that can handle analog signals. Plus, we've brought a direct knock sensor input out here. This lets you bypass the GM ESC module, and set different sensitivity levels based on RPM and what cylinder is firing. There's also a ground and a 5 volt supply wire for your sensors included on this connector.
If that's not enough I/O, we've brought out the CAN bus connection as well. You can use this for a MicroSquirt running IO Box firmware, our eight channel EGT module, a controller for a 4L80E transmission, a Racepak or Race Technologies dash - or all of the above.
And last - we just knew we'd have some customers ask if it will run other GM V6s, like 2.8 Fieros and F bodies. And the answer is that it does fit a few of these applications. (Sorry, SyTy guys and Turbo T/As - your wiring is too different. We checked.) And we expected that those guys' next question is, "Will it run sequential injection on my V6?" So, to make that easier, we brought out four of the main injector outputs and the cam signal.
