$USD 305.0
Out of stock
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. 9 digital inputs 5 of them can be used as analog or digital. Bluetooth as optional connectivity , SD card logging, Real time clock.

Hey, I am in the process of designing a pnp hat for sem301 for e36 BMW ms41 DME’s.
Could i possible have the footprint of the board and the connector layout please.
Regards,
A Masood.
