Open up your Base VE table, press the Overlay button, and select that same log file that you posted. Then step through the file point-by-point and adjust your VE values by the amount of your O2 correction for each table value that you encountered during the run that you logged.

thanks dfi guy...i figured thats what you do...do you think its necessary to tune on a dyno???i do have the wideband setup...right now i am primarily working on the fuel map,however i am not really sure how to tune the timing map...any info you could give would be great...
thanks,mike

A dyno obviously makes tuning quicker and easier, especially on the timing side of things. You can't beat having raw numbers to compare run by run to see exactly what the changes you've made have done -- especially for timing adjustments. For a price, it can eliminate most of the unknowns involved with tuning by feel on the street. If you are new to tuning, I'd strongly suggest some dyno time until you get a feeling for exactly how changing a given tuning parameter will affect the operation of the engine. A wideband is very helpful, but remember to treat it as a tuning aid rather than a failsafe that will "protect" you from any tuning mistakes that you might make.

thanks for the reply...just for the record i'm not relying on the wideband...i'm getting it tuned so there is only 5% correction(on the rich side)...thanks again dfi guy....
