Stag 300 Premium - Jaguar XJR Oxygen Sensors

Postprzez markocosic » 01 cze 2012 01:42

Hello,


I am fitting a Stag 300 Premium system to a 2002 Daimler Super V8 (Jaguar XJR) with the supercharged AJ27S 4.0 litre engine. (370km)

Stag 300 Premium 8
2* STAG-EU4E Europa/Bosch (emulators)
2* KME Gold Turbo (reducers)
8* HANA H2000 A-Type/Green 1.9 ohm (injectors)


I have some questions about the oxygen sensor/lambda sensor:

The Jaguar has an upstream (before catalyst) sensor and a downstream (after catalyst) sensor. The upstream sensor is described as a "linear" sensor, but has four wires. The original part is a Denso 192400-3101:

http://www.gendan.co.uk/product_LBX0429.html

What type of sensor is this?

Is it like the Bosch LSM-11?

Thank you,

Hi, please to ask guys from that web-company... unfortunately we are not sure what kind of oxygen sensor/measuring device they've showed you.

It's standard narrow band oxygen sensor.
4 wires are: signal(grey) ,heater(white) ground(grey)

Hello,

Thanks for the replies. To answer my own post - these are NOT the standard 4-wire universal sensors. This model uses a "constant voltage linear air fuel sensor" according to the dealer manual. Voltage on the blue wire is always 3.8V exactly. Change the wiring and set to "UEGO Full Range" and it the Gas Synchro software can read ONE of the sensors.

This is enough for this engine. (the fuel trims on petrol are very very close so if the injection times are right for one bank they will be right for the other too)

"2.5" is rich
Less is lean
Normally the engine runs around "2.0" in closed loop mode.

Find over the head of engine , at the end of engine chamber there is a solenoid-valve on cooling pipe, disconnect the socket , after this everything will work properly.
