Buy Bosch LSU 4.0/4.2/4.9 SensorsOur controllers work with Bosch LSU sensors. Note (*): if the 7057 sensor is out of stock then we will automatically ship the 7200 (from 18 April 2007 they are the same price because of price increases.) |
The lead lengths of 5 sensors Tech Edge sells is shown in the image at right. The full part numbers for these sensors, and other NTK sensors is shown below.
The four sensors 6 066, 7 057/, 7 200 & 17 025 are Bosch LSU wideband pump cell sensors. They are described in more detail in the special LSU section and they are all sold by Tech Edge. WBo2 was specifically designed around the LSU sensor and all relevant Bosch operating conditions (including the exacting "light off" warmup characteristics) are rigorously observed. The 06 066 sensor is normally called an LSU 4.0 (although some documentation calls it an LSU 4.2) , and the 07 057 & 07 200 are LSU 4.2 variants. The 17 025 is an LSU 4.9 which is designed to work well in diesel and lean burn applications.
One major difference between these sensors is the "head" design that is fairly open in the 6066 but is more restricted in the 7057 & 7200 sensors. An open head results in faster Lambda sensing, but also make the internal pump cell more sensitive to exhaust gas temperature variations, with the possibility of over-heating or under-cooling if the sensor is located closer of further from the optimal position. In general, we recommend the lower cost 7057 & 7200 over the 6066.
Another important difference with these LSU sensors is the connector itself. The flat 6 pin 6066 is different to the 2 by 3 pin rectangular 7057 & 7200 connector. More connector information here.
The L1H1, L2H2 & NTK-VW sensors are NTK/Honda UEGO wideband pump cell sensors. The name UEGO is traditionally associated with this range of sensors, and stands for Universal Exhaust Gas Oxygen. They were co-developed by Honda & NTK (the speciality ceramics division of NGK) and first appeared in the early 1990s on Honda 1.5 Litre engines. There's some more information relating to the older Tech Edge 1.5 unit and the L1H1. They predate the Bosch LSU sensor but, apart from the higher price Honda seems to want to maintain, are still good sensors. The L2H2 is the updated L1H1 and neither are sold by Tech Edge. Just to confuse you, Bosch source the L1H1 sensor from NTK and package it as their 13246 sensor.
Tech Edge does NOT sell the L1H1/L2H2.
Tech Edge has small quantities of the NTK-VW sensor which is similar to the L2H2
but is branded as Volkswagen part number 036-906-262-B - it also has a different connector
and a different calibration resistor scheme.
We DON'T actively recommend NOR advertise this sensor on our order page.
Tech Edge also sells the LSM-11 (Bosch part #0 258 104 002). This sensor is not a wideband sensor (in the true sense of the pump cell sensors) but has been used with controllers described as wideband controllers. Here is some Bosch on-line information on the LSM-11 (PDF format). Many older "wideband" coontrollers use the LSM-11 including Autronic and MoTeC controllers.
Tech Edge sells the LSM-11 only because there is a demand for it from users who have legacy equipment. We don't recommend people use this sensor when accurate and robust LSU sensors are now so inexpensive, often costing one fifth the price of the LSM-11.
