I'm trying to figure out if there are any ways that I can monitor my A/F during regular driving and not only in WOT like my current autometer.... besides wideband... would you need to be in WOT for the DEfi or the GReddy A/F gauge???

 

you need to always be at WOT and even then, those aftermarket a/f ratio meters are crap, get on a true wideband please

 

Using a Tech Edge Wideband. I know my real a/f at all times

 

with an FJO.
