I have two O2 sensors. One on cylinders 1-3 and the other on cylinders 4-6.
The dual AFR gauge on my console has helped me get the carbs responding well and the spark plugs a nice tan color with a clean and happy powerband.
BMW have two lamba sensors on their engines. Well when they made proper engines
Its an option I can look into....easy enough to produce.
you just need to make sure your factory allow for the length of the sensor on the merge collector.
I think anywhere above horizontal is "optimal".
And angle - optimum of 40° ?
have your factory got a car they can line it up on? Are there any s30's in china? Or if there are, are they being imported by 'new money' there? might be a growing market?
you'll have to consult a specialist.
Not an armchair hero then...
...plenty on here but luckily, I know what I'm doing, have ramps and a selection of early to late S30s upon which to experiment.
Isn’t that a upstream and downstream sensor either side of the catalytic converterBMW have two lamba sensors on their engines. Well when they made proper engines
