Support chips for Bosch LSU4 O2 sensor
Support chips for Bosch LSU4 O2 sensor
(OP)
I would like to construct a wideband o2 sensor using a Bosch LSU4 sensor. I have a front sensor from a VW 1.8 engine ( about US$40.00 ). I understand that there are some Bosch support IC's for this application, part numbers CJ110 and CJ125. Does anyone know where I could purchase these parts and their data sheets?
Also, the only technical info I have for this sensor is the 22 page Bosch (english)document dated 25.1.99 . I would appreciate any other tech info that you could point me to.
Thanks,
-Dana

It really depends on how wide a range you want to measure and the level of accuracy you require. I have found that sensor to be very inaccurate below 13.5 A/F and above 15.1 A/F for gasoline. These limitations of that sensor may not be what you want, or can live with. There are several sources for wideband meters, in no particular order...Bosch, Motec, Lambdaboy, FJO Enterprises, Horiba.
I have not seen any more recent data on the LSU4 than what you have.

Tell me where you buy them for $40 and will order a bunch...
Hope this helps
