[T3] exhaust tester

[Keith Park]

I have the sensor on the top RHS of the stock T3 muffler, where Im told it
is best in a stock application. CHT has never been a problem, even with the
T4 motor the heads ran really cool, it's the oil that heats up although with
the stock motor that's not a real problem till I get out in the desert.

I run the OTT from ISP west and the sensor is in the collector just  
before the muffler joint.

Where is the sensor located on yours? if it's further downstream then  
you should have leaner readings with air coming in to the exhaust  
chamber at cruise.
Your plugs will tell you as well if things are on the right track.

The trouble with being on the slightly rich side is the increased  
cylinder head temp.
