Standalone Engine Management SEM306 Based on MS3x
Out of stock
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 without harness only mating connector and terminals. Bluetooth as main connectivity and USB as backup and to configure the Bluetooth name and pin code, SD card logging, Real time clock.
- 2x Deffrential Trigger inputs (Hall, VR and Opto).
- 16x High impedance low side output 3A each to drive injectors or to be used for auxiliary outputs.
- 8x Ignition output 1A max (5V or 12V)/ 4 of them shared with inputs
- 5x Inputs can be used as analog or digital input.
- 3x Digital inputs.
- 4 digital inuts shared with Ignition outputs.
- 4x dedicated analog input, coolant temperature, Intake air temperature, O2 sensor, Throttle position.

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
Installation manual is available now under download tab.
write me on +201001913875
How is connected the can-bus network on this ECU? . I didn’t see any connector on the PCB diagram or wiring diagram
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.
Do you have USB driver for Linux?
Unfortunately, only windows.
Is it built in whideband controller or do u have to use external?
No built in wideband, we have external wideband controller.
I have asked again but now i am thinking again to try it.Can i run a 5 cylinder engine full sequential injection and direct ignition?
Yes, it is possible.
Hi, Can I use it with 6g72 MY1989 with distributor?
Hi, I have not tried our ECU on all engines, however I have some client who install it in engine same like yours.
Hätte zu der sem 306 gerne eine Kabelbaum mit 2,5 Meter. Wo kann ich das beim bestellen angeben?
Can you use antilag with this standalone?
Does it come with wiring kit or plug or nothing?
Comes with connectors and terminals. no wiring.
