Here are some of the questions we have been asked.

Can I fit only 1 ECU and keep a magneto?

While technically possible, it is not a supported system. With only 1 ECU there is no redundant fuel injection system. A second issue is that the magneto becomes at best a backup ignition system only. The magneto will have fixed timing at (typically) 25 degrees BTDC and since the ECU will often have greater advance the mixture will already be burning before the magneto fires.

Do you use aviation spark plugs, if not what kind do you recommend?

We don't support aviation spark plugs, and we provide adapters to 14mm automotive style plugs. It is up to the owner/engine builder to select and source spark plugs. We use NGK BR8ES plugs which work well.

Can I use a carburetor style fuel pump on an upgrade?

No the system needs a high pressure Lycoming mechanical pump and 30 psi electric boost pump.

How does the system adapt for changing fuel pressure?

While the actual software that does this is proprietary to Kotuku, the system is designed to use fuel injectors that are provided with a flow map. This is entered into the CanFly Commander for each cylinder. This allows the software to calculate the exact time the injector is open to deliver the correct amount of fuel.

Why do I have to finish the spark plug leads?

The length of the leads is dependent on the baffle/exhaust and actual type of engine. There are too many variables for us to make a pre-made set of leads. There are instructions on how to terminate the leads.

You make the loom from the ECU to the fuel injectors and throttle body. Why?

A critical part of the ECU and fuel delivery system is the wiring from the ECU. We make the cables long enough to reach to the standard parts of the engine. It needs finishing by the builder. We make the loom so that the connectors are properly assembled and all of the wires are crimped correctly.

There are 4 flying wires that are 5 ft long that the builder must terminate. These are Power, Ground, Tach and Inhibit.

If there is a special design, just let us know the cable lengths you need and we will make a custom loom for you.

Crazy mouse when plugging into a CanFly Adapter useinf Microsoft Windows

When you connect to a CanFly® USB adapter the system exposes the CanFly® as a serial port. Unfortunately windows can mis-interpret the serial data stream as a mouse.

To resolve this please follow the guide to (disable the serenum)[/Wiki/serenum-disable] for the port.
