Description

The UA4C gets it’s name “Under Arduino 4 Channel”, as the Arduino Mega sits on top of the Speeduino PCB.
This combined with an all surface mount part design give all the functionality and more of the 0.4 Speeduino in a much slimmer package.

This item consists of: UA4C Speeduino PCB, Mega2560 board, Metal enclosure, End plates with MAP fitting, 2 plugs and 46 crimps.
The ECU will have the latest firmware loaded, a test base-map will also be on the unit.

This is the new version of the UA4C vB3 Sea Fox, improvements over earlier Sea Wolf  models include

• Rearranging the serial headers for better fitment in the slim case
• Upgrading the low current outputs, they now support larger loads and are self-protecting
• Changed tachometer circuit to allow 5V, 12V, and high voltage tachometers
• Added indicator LED for 5V power, and improved labeling

Outputs:

• 4 ignition channels (Low/Logic level)
• 4 injector channels
• 4 high current outputs
  • Idle
  • Idle 2
  • Boost
  • VVT
• 8 low current outputs
  • Fuel pump
  • Tachometer
  • Fan
  • Fan 2
  • Aux 1-4
• Stepper Idle Control with optional module
• 5v Sensor supply

Inputs:

• Throttle position sensor (TPS)
• Coolant temperature sensor (CLT)
• Air temperature sensor (IAT)
• 4 BAR Manifold pressure sensor (MAP)
• 2nd Internal MAP sensor for barometric compensation as standard
• O2 sensor (narrowband or wideband)
• Launch control (Clutch switch)
• Knock (Due in future firmware update)
• Flex fuel
• 2 spare inputs
• Hall Effect Crank/Cam (VR with optional internal module)
