MBE9M4 ECU, Fuel Injection up to 4-cylinders
MBE9M4
The MBE9M4 is a very powerful ECU for its cost and has the same map designs as the more Advanced ECU in the MBE Range it has 16-bit Fuel & Ignition maps for ultra-fine adjustment. They also have 16 load sites and 64 speed sites which are movable to allow ultra-fine tuning especially useful for engines that are highly tuned and can have very fussy requirements.
This is the new version which has superseded the MBE9A4, all the pinouts and instruction sheets are the same as the 9A4 versions.
This ECU is designed for sequential fuelling on engines up to 4 cylinders (high impedance injectors). It can run Wasted Spark or Coil on plug engines up to 4 cylinders. It is generally designed to allow the user to optimize the fuel & ignition settings to get the best out of an engine.
It uses USB communication from your laptop, which is then converted into CAN by a small piece of hardware (MBE985), which is a more stable system, used by car manufacturers worldwide. You will need our basic CAN mapping kit MBE-MAP-KIT-3-CAN and the necessary adaptor, if you are using one of our harnesses, to read information and/or make changes to the mapping in the ECU.
All MBE ECUs supplied by SBD will be loaded with a start base map free of charge, it is also possible to build more advanced maps with additional features and function, please contact SBD for costs. In addition, they are capable of being adjusted by the user via a computer. All ECUs are fully tested during manufacture and again before dispatch once the map has been loaded.
The reason MBE ECUs are specifically built for crank and cam sensor types, and ignition driver types is done for several reasons, some types of circuitry would require additional pins to function correctly. This means that you are using up valuable pins on the ECU that can be used for other functions. Also trying to make circuits cope with every type of sensor and coil compromises their design, so have circuits built to specific sensor types gives better accuracy for incoming information from its sensors and better control of components such as coils that the ECU would be driving.
 
This ECU has so much more functionality.  Call us for further info.
