I had only read about them in ND.
That first night it taught us all a thing or two!! Racing wasn't the same, less cut and try, until 1991 when we first got the Super flow dyno... Talk about Data overload...
Well so much for the stroll down memory lane.
I do want to mention one other thing about using 02's to tune. Last year when I was doing Tech at the Engine Masters I noticed quite a few of engine guys tuned only with the 02.
You know that is O.K., but there was a problem with the fuel (that is another story) and most engines were running in detonation. You could watch and tell who the old school tuners were.
As a Tech Inspector I couldn't say anything to help the participants and it hurt me to watch the results of tuning an engine in detonation with a 02 sensor. If it detonates do yourself a favor and throw that data away. I'm sure it has a lot to do with the type sensor, but they can read some nasty nox when the engine detonates and give false readings. Learning to read plugs and crossreference data is important. OK, thanks for reading my ramble..... It's time to wash this nasty hone oil smell off and get in bed.

If we do not watch we are going to tell our age. I too have seen my world change when I built the Tech Edge out of Australia. Was the first O2 I had seen but it was the tip of the ice berg. And you are correct on data overload. My dyno has 46 channels to log data. Hell when I make a pull Im thru for the day just to look at data and make decisions. My brain aint got but one channel and most of the time it goes in the wrong direction. And man are you ever correct on detonation. No way will I tune by O2 alone. Very often I will not even make a pull on the dyno unless the weather makes a change.
