Acceptable Parameters

[b4c2002camaro]

I am considering purchasing a U7198 for my 2002 Camaro LS1. After installing the performance tune, in monitoring real time data, where do I find what are acceptable parameters for the air fuel ratio (rich/lean)? They do not seem to be in the tool and they are not in the downloadable manual.

A/F can only be viewed by using a wideband O2 sensor.
I would suggest putting the car on a dyno to see what the A/F looks like.

Thanks
Mike

Thanks, Mike. I ordered a U7198 yesterday instead of getting a dyno tune. My question should have been: After installing the performance tune and monitoring real time readings, how do I know if the readings are where I want them to be or if they should be increased or decreased?
