MBE9A9 ECU, Fuel Injection up to 8-cylinders
MBE9A9
The MBE9A9 is the most advanced ECU that MBE has released to the motorsport market. The technology put into the ECU has been developed through its many years of production car ECU development which has allowed us to produce a very high level ECU but at an affordable price. MBE & SBD have spent the last 3 years refining the software & user interface ready for high level motorsport use. The ECU has also been tested for the full year by SBD on our own race car prior to its release into the market.
The MBE9A9 has high side & low side drivers, this means you have the option to either drive the outputs directly from the ECU with no relays or use a low side driver to drive it via relay. The MBE9A9 ECU’s are built to customer specification, we will need full engine details with your order.
Crank Sensor & Trigger Wheel Input
Crank sensors are most commonly of the inductive type, you can normally use the original crank sensor. If your engine uses the hall effect type, MBE ECUs can be built to order. MBE write special code to allow the use of a range of different trigger wheels, most commonly 60-2(GM/VW/Bosch), 36-1(Ford), 24-1(Suzuki Hayabusa) & 24-2(Suzuki Hayabusa 2008 & other late Japanese bike engines). Other trigger wheels may become available, download Easimap 6 to check current types. We can supply a range of specialist sensors & suitable trigger wheels for applications that currently have no trigger wheel.
A special piece of software has been written by MBE called soft start, this was produced due to known problem with the standard starter motors, that if the battery got a bit low sometimes the engine would kick back on starting and engage the starter clutch. This would, if you were lucky only damage the starter clutch itself, but if unlucky could break off part of the engine cases. Without going into too much detail, the ECU allows the engine to get up to speed during cranking before attempting to start the engine, if the engine does not reach sufficient speed it will not allow the engine to start, so damage can not occur.
Fly by Wire (EGas) 
Fly-by-wire is a system that is used by most current production cars and an increasing number of production motorcycles. Fly-by-wire allows the manufacturer to accurately control emissions, idle speed, torque and other parameters and also aids safety by eliminating the chance of a sticking throttle mechanism. In simplistic terms the accelerator pedal is no longer connected by a cable to the throttle butterfly or butterflies of the engine. The accelerator pedal position is read by the Engine Management System which then determines in conjunction with various other factors the required position of the throttle(s). The throttle is moved into the required position by a position controlled motor under control of the Engine Management System. The Engine Management System continuously monitors the accelerator position and throttle(s) position, any discrepancies in any of the readings will result in the system resorting to a safe mode. It makes decisions, if everything is ok, based on what the driver has requested with the accelerator pedal e.g. if the accelerator is closed the ECU will try to maintain idle but continually adjust the butterfly position to help maintain the best emissions, when the driver opens the accelerator hard it will move the butterfly in a manner that optimizes engine performance and emissions especially on turbocharged engines.
 
This ECU has much much more but we simply dont have room on this page for the info.  Call us to discuss further.
