you might try putting the bung in a tube vs collector...was thinking about trying that...don't waste you $$$ on putting in collector...

I have made quite a bit of progress with this experiment this week. Still have not killed a sensor. Currently I have the tip of my sniffer tube positioned 3" aft of the front end of my collector. Approx. 6" before the point water mixes in. I am pretty confident I am receiving an accurate AFR reading as I have compared plug readings and the general sound and feel of the motor to my AFR readings .As well I have confirmed these settings with the seasoned pro that originally set-up my Pro Charger. I have made some runs with this new set-up and have been able to do some fine tuning on the motor and am pleased with the results.

I do believe I have the longer collectors[ATTACH=CONFIG]524265[/ATTACH]

I wonder if a bigger pipe would help like 2-3" dia. 0r biggest to fit past the internal flappers if there are any. Maybe enough exhaust volumn to keep some of the heat in the exhaust going by the sensor.

I've decided to hhave you come out and plumb up the gas lines for my furnace in the garage.

The sensor i am using is self heating.

I wonder what happens to the gasses when they cool, is it an accurate reading now?

I have inserted a link to a device used on Motorcycles that is very similar to what i am using. They claim virtually no difference

What does the curled up section of pipe do for the whole thing?
