SKU: sem306 Category:

Overview

Standalone engine management system based on Megasquirt MS3x Processor and firmware with enhanced inputs and output ports in sealed enclosure and sealed automotive connector. It is capable of controlling sequential injection on engines up to 8 cylinders, or semi-sequential up to 16 cylinders, combined with direct fire ignition for engines up to 8 cylinders or wasted spark ignition on engines up to 16 cylinders. Can be connected as fully standalone ECU or as piggyback and share the sensor reading with the stock ECU as it has differential trigger inputs, The 4 bar internal MAP sensor can read up to 44psi of boost, 2 Programmable knocking detector circuit can be used to adjust the ignition timing,  5V ref voltage, and internal switch to pull up resistor.  It has dedicated inputs (Crank, CAM, CLT, IAT, MAP, TPS, O2 and knocking) and 16 low side outputs to drive injectors or any solenoid valve. 4 dedicated ignition outputs and 4 ignition outputs shared with inputs. 8 digital inputs 5 of them can be used as analog or digital. It comes with 1.4 meter harness and USB cable. Bluetooth as main connectivity and USB as backup and to configure the Bluetooth name and pin code, SD card logging, Real time clock.

  1. Good afternoon. I would like a little more information about the new ecu. they already have the manual they could send it to me how many pins does the neva ecu have

    They have a WhatsApp contact to speak more easily

    Thanks for your time

  2. How is connected the can-bus network on this ECU? . I didn’t see any connector on the PCB diagram or wiring diagram

    1. In this version there is no CAN bus on the external connector, however CAN bus chip on board. Next version SEM307 will have CAN bus as shared with inputs.
