Wide band o2 tuning....

I would like a meter that I can record on a sd card and download on to a labtop.. I assume I would want to monitor both banks of the engine and also monitor engine rpm? Last time I researched I came up with the innovative lm2 I think it was. Is there anything better suited for what I want to do? I'd like to tune my truck for good cruising manners as well as best performance at the track... Also wondering if there's anything else I should be aware of... Anybody use these types of tuning aids? Good or bad experiences? Thanks

Thanks.... I will check that one out also.... Can a guy tune a methanol burning engine with these setups? I'm still toying with the idea of switching from pump gas to methanol... Thanks

It's a different meter for both.
