[BLSTIC]

I plan to run the test at idle like this:

Hook up the unit so that there is airflow through the bubbler tank going into the engine at all times (hooking the bubber up to vacuum and introducing a small leak would work well). When the engine is hot, turn on the cell (this will introduce H2 and O2 into the already flowing airstream). If the idle changes AT ALL, turn the unit off and see if the idle returns to normal. This will test for changes to combustion.

If there is no change, turn the unit off, and tune the motor (ignition timing and fuel mixture screw) for the leanest possible mixture. Then turn the unit on and see if I can make it run leaner again. This will test for lean burn limits.

If either test is promising, the unit will be installed on my far more modern vehicle, and to the dyno i go...
