Link G4X AtomX Wire-In ECU (111-4000)

The AtomX is the entry point to Link's G4X wire-in range, built for engines up to four cylinders or two rotors that need sequential injection and direct spark without a long list of extra inputs and outputs. It runs the same processor, firmware and PCLink software as the larger G4X units, so the core tuning tools are all there in a compact nylon case. If the build calls for VVT, closed-loop boost or launch control, the MonsoonX is the next step up.

Highlights

• Sequential injection and direct spark for up to 4 cylinders or 2 rotors
• VE or traditional fuel modelling, individual cylinder corrections and dual fuel and ignition maps
• Flex fuel, flexible engine protection limiters and a built-in trigger oscilloscope
• Open-loop boost control with up to three switchable tables, plus on/off cam control for VTEC-style systems
• CAN bus with CAN keypad control, an OBDII output stream and CAN or serial data for aftermarket dashes
• 512MB of onboard data logging and 8 custom math blocks
