The UA4C uses SMD technology to make a 4 ignition/4 injection channel board smaller, and with more features. It is a bottom mounted Arduino MEGA shield. The MEGA is placed upside down on top of it.
This makes the total ECU package size a 4.25in x 5.75in footprint, and less than 1.5in thick.
All of the outputs (except for stepper idle) include an LED for quick troubleshooting during setup.
An externally accessible jumper blocks resetting of the system when a USB cable is connected.
All of our Speeduino Fishdog ECUs come fully assembled, stepper idle driver, and dual vr conditioner mounted, Mega2560 pre loaded with firmware, cased with printed end caps, and ready to complete your engine management needs.
Harness options include:
No harness, headers and pins included
2ft harness, fully pinned with 2ft of 20awg TXL/GXL
8ft harness, fully pinned with 8ft of 20awg TXL/GXL
