Dave the file you up loaded appears to be a data log??? what am I looking for in it?
how do I know if the tuner pro is seeing and displaying 0-5 volts correctly?

so I played it back and the wide band did not move or show any data.
I played back using my bin file, advance 0, and 217 files.
Try using the attached .adx file to playback the data log I posted. The attached is the .adx file I'm using, so I know it's good.
The exported .csv data log shows WBO2 data.

Hello Dave, when I used your ADX file, the target AFR dial gauge was reading 14+/-. also when I used it to play the data log, it was operating correctly.
The Wide band square below dial gauge was reading 11 and the AEM gauge was reading 14.
Tomorrow I am planning the see what the voltage reading is with a meter on the analog wire when warmed up.
I am looking to confirm the AEM gauge showing 14 is sending the matching "X" voltage to the ECM. This is just a sanity check.
If it is matching then we know its in the ECM or the scalers or something.
Step one is confirm voltage.

I seldom compare what the WBO2 is showing vs. what TunerPro RT is showing. I spend 99.98% of my time working with Excel spreadsheet.
Sometimes I pour some gas into the throttle body to verify lean WBO2 readings are really lean. Pouring gas into the throttle body will temporarily make the engine run rich and the WBO2 will temporarily show rich AFR's.
I wonder if blowing compressed air into the throttle body (throttle blades closed) will cause a rich running engine to temporarily run lean. Seems logical, but I've never tried blowing compressed air into a rich running engine.
