What engines are compatible with OpenLogicEFI ECUs?
Speeduino-compatible universal standalone ECUs can be made to work with most gasoline engines. However, there are some limitations. The most significant are outlined in this FAQ, while others can be found in the official Speeduino Wiki. These systems are ideal for enthusiasts and professionals comfortable with custom setups.

Can OpenLogicEFI ECUs support direct injection?
Currently, Speeduino firmware does not support direct injection systems. This limitation applies to all ECUs compatible with the official Speeduino platform.

Does the ECU support drive-by-wire throttle bodies?
Speeduino firmware does not support drive-by-wire throttle body control. However, most standalone drive-by-wire controllers can be used in conjunction with Speeduino-compatible devices.

Does OpenLogicEFI provide installation assistance?
Due to the universal design of our products, we do not provide direct installation assistance. However, extensive resources are available, including schematics, pinouts, and official Speeduino installation guides. Additionally, the Speeduino community forum and Discord are excellent platforms where users and developers can assist with your questions.

We highly recommend the official Speeduino Wiki for the most comprehensive and detailed information, including universal installation instructions. All ATmega (Arduino Mega2560)-powered OpenLogicEFI ECUs are compatible with Speeduino firmware and based on the v0.4x platform.
