| Air, water and aux temp inputs | 4k7 pull-up (requires separate thermistor connected to ground), 32-point linearly interpolated calibration, range -30 to 125°C |
| EGO input | 0 – 1V factory narrowband, or Bosch “wideband” – input impedance 10 MOhm. Can connect 0-5V linearised sensor (eg PLX, M&W UEGO) to aux input Can connect 0-3V Zietronix sensor to analogue input Can connect M&W UEGO, TechEdge, Innovate LC-1 and TC-4 on secondary serial port |
| Knock input | High impedance input, filtered |

| Auxiliary digital inputs | 8 inputs, each configurable as active-high or active-low, 12V tolerant inputs |
Actuator Interfaces | |
| Number of injector drivers | 4 |
| Injector driver waveforms | Full sequential Batch Semi-sequential every period or semi-sequential every second period Half/third/quarter speed full sequential Fire all at once every cylinder 1 (as on Swift GTi, Alpine Renault) Optional batch fire during cranking |
| Injector driver current | Optional constant current or peak-hold drive, selectable steady-state current of 0.5A, 0.9A, 1.5A or 1.9A |
| Number ignition outputs | 4 (using 4th channel disables aux output 1) |
| Ignition output waveforms | Selectable as firing on rising edge or falling edge |
| Ignition output type | Open-collector with 560Ohm pull-up (allows direct connection to OEM transistor or separate igniter box) |
| Number of auxiliary outputs | 8 (or 7 if using 4 ignition channels) |
| High current outputs | Max current 7A (or 3A inductive), 3 of these PWM capable, PWM frequency selectable (23Hz – 2kHz) |

| Load determination and Tuning Modes | Optional Volumetric Efficiency Tuning TPS or MAP based |
| Injector pulse width resolution | 0.7µs (0 – 44ms) |
| Ignition resolution | 0.2° (0 – 51°) |
| Dwell time resolution | 0.1ms (0.1ms – 5ms) Dwell time reduction for high RPM with high dwell time |
| Accelerator pump | TPS and/or MAP based (configurable proportionality) as well as asynchronous accelerator pump. Works with TPS pot or switch – pot gives better performance |
