Beedub said:i welded a boss into the S pipe after the headers. Be prepared to keep changing the sensor tho, they dont last long. I need to replace my again.
its very nice to keep an eye on AFR during WOT for long periods... a boosted s54 likes mid 11s-12 AFR ,
visible here in this very old video, ill be pulling my finger out next spring and releasing a proper video series on this car.

gauge is a stack professional gauge using bosch lsu 4.9 sensor. This data logs back to a stack unit in the glove box.
this gauge was around 360gbp if i remember correctly.

Thermal shock is usually what kills the wideband sensors. The factory sensors won’t start heating up until the engine is actually running. An aftermarket wideband tied to an ignition-on power source will start heating up immediately when the key is turned. Moisture from a cold start contacting a hot sensor can severely shorten the life of the sensor. Additionally, check to see if the “nose” end of the sensor is angled down at least 10 deg, so that moisture drains out into the exhaust rather than pooling on the sensor.
Bosch 4.9 respond more quickly than 4.2 but seem to be less durable.

id rather this than my engine running lean and not knowing..... you have to pay to play!!
Martyn said:It has a pair of wideband O2s fitted as stock, but you won't be able to wire a gauge in to them. You may be able to get something that reads the AFR via OBD2 though.
Martyn said:You'll be fine with that! I use the stock WB when logging / tuning without issue.
Vanne said:Both are nice cheap options, Byron has the proper setup which is what i would go for. 100 sterlin a year is cheap insurance. Not sure where the obd2 gets its AFR info from (its probably on the canbus, a mathematical calculation at best), but id like mine from a real time sensor.
