LSU4 UEGO Operators Manual
The M&W Uego system uses a Universal Exhaust Gas Oxygen sensor and this works completely differently from a normal oxygen sensor you would find in your car. It allows precise measurement over a wide AFR range. UEGO sensor systems are used by all original equipment manufacturers for ECU mapping and are also widely used in motorsports including F1.
The microprocessor controlled M&W Uego controller features a fully linerized real time 0 to 5 volt analog output giving 10 to 20/1 air fuel ratio.
This simple scaling allows easy input into data acquisition systems and engine management systems. 12V operation with a cigarette lighter plug allows easy fitment for vehicle testing.
The RS232 port allows connection to IBM compatible computers and laptops with DOS, Windows 95/98/NT/2000/XP and PocketPC software available. The controller uses a true wide range Bosch LSU4 sensor which when used with the tail pipe probe adapter provides a very versatile tuning tool for engine mapping and diagnostic purposes.
The sensor uses a special pumping cell with gives a current output depending on the air fuel ratio. This is completely different to a “normal” oxygen sensor. The pumping cell design allows measurement of air fuel ratios over the whole range where as a “normal” oxygen sensor is only capable of measuring a small range either side of 14.7/1 air fuel ratio. Each wide range sensor is calibrated and supplied with a calibration chip which can be easily changed should a replacement sensor be required.
Note: the sensor contains a ceramic module and should not be subject to mechanical or thermal shock or it may be damaged
