Holley EFI throttle body 112-588

What does a guy use for an ecm and wiring? Or is this just an upgrade to a stock system? Kim

Can use any ecu that takes these inputs and is programmable such as megasquirt or the Holley line of Ecus. Don’t know if I would recommend it with an oem ecu as they might not allow for calibration of the TPS, IAT and IAC motor. This would typically be used with a port injection system.
