This is the follow-on test for the test I put up a couple of days ago. For this test, I connect the Sunpro gage to my narrow band O2 sensor. I think my results show me that I can use this simple system to at least predict a CHANGE in A/F ratio (with a given load) before the genset governor goes wide open. This, hopefully, will give me a chance to do something about it.
Thanks Pete! I was planning on setting mixture by ear alone but now when I see your simple setup, I just might verify what I am hearing with the help of what I can see also. That looks simple enough that even I could do it.
