Tifosi: Perhaps you did not read my text. I explained the settings being tried, (including NB/WB) and they conform to the suggestions you are making.From the edge of things:
Define 'way out of whack' mixture.
...Then there's the whole wideband vs narrowband output voltage and having to tell the ECU specifically which one you're using...
When you try it, how does the computer react to the sensor? It's almost as if it's reacting backwards. Also, most closed loops system allow you to bracket how rich and lean you go while using the sensor- so you should be able to keep correct.Tifosi: Perhaps you did not read my text.

When the feature is engaged, the mixture immediately moves lean, and continues for a few moments until 17+ is reached and the car dies.
If someone has this feature actually working on a GoTech, I would be motivated to spend more time testing variations. As it is, I've put more time into it than should be necessary. I have been tempted to buy a newer "Pro" unit, but can't consider the $$$ unless I knew it would address the issue.

I read the text, (otherwise I wouldn't have replied, or the reply woulda been so far off topic it wouldn't have funny), but didn't see any explination other than that you'd tried WB and NB and neither would allow proper closed loop function without making the mixture 'out of whack' :shrug:Tifosi: Perhaps you did not read my text
MichaelGreetings Eric: Reacting backwards is my interpretation also.
The GoTech does have bracketing for how much to adjust, and those show up on the load graphs when running the software monitor. You are making a good suggestion - if I limit the bracket to a very small adjustment, the thing should still run regardless.
And yes, the WB and NB relationship to AFR are not only over a smaller range (5v, 1v), they are reversed direction. NB voltage goes down with increasing AFM, while WB goes up.
I know for certain that the GoTech controller is seeing the correct NB/WB value, since the AFM displayed on the GoTech tuning software panel tracks that shown on the meter itself. If that is set wrong, they don't agree.
The NB/WB digital output selection switch on my sensor is located on the back of the meter, which requires me to remove it to get it changed to any other mode. Did it twice, WB>NB>WB, and not really interesting in doing it again
Greetings Eric: Seems we reached the same conclusion. The guide you reference does not even mention the O2 sensor type selection, which is on the extended options screen (X)I found the gotech site, and found the closed loop fuel guide.
...Sadly, I'm not very impressed with the little I've read. Just leave it off.
