hi guys,

i've heard that the typical autometer air fuel gauges arn't accurate at all... how true is this?

in light of that, what do you recommend to monitor the air/fuel ratio? Not looking to do any hardcore tuning, but moreso simply monitor it so i can make a few slight adjustments if necessary.

Thanks.

how about just an EGT(exhuast gas temp) or oil temp?? this can indicate if your running too lean..

not really, engine temps can increase due to more than one factor so it really doesnt tell you if you are rich or lean
