[T3] Started after seven years, now what?

[Keith Park]

The LC1 is a lambda that gives voltage outputs in the range of 1-5, and
converts that to an AFR reading, that's what is used to tune the engine.
The Lambda that my LC1 uses is a heated sensor, for use in cooler areas if
necessary, its  a wide band sensor.

On the OE style mufflers that DON'T have the best OE internal 
construction, the upper right would be the hottest place, closest to 
the cylinder, but that still comes after the upper heat exchanger, so 
I don't know how well it would work with a Lambda sensor.

A Lambda sensor would work better with an extractor exhaust, where it 
could be installed right outside the exhaust port. In that case, #4 
might be the better choice, since there is more room there, but #2 
might work just as well.

There are other types of fuel/air sensors that need cool gas to work 
properly. That's what the emission stations would use, when they 
stick a sampling tube up the tailpipe. I have a Heathkit that does 
that, but it doesn't work very well. I think I need to add a voltage 
regulator to it, to make it stable.

The Lambda sensors also just pretty much just have 3 states: rich, 
just right, and lean. They don't tell you how rich or how lean. The 
cool gas sensors work better at that.
