When you go onto a dyno how do they test the air/fuel ratio? do all tuners use a wideband o2 sensor?

also i get to help the tuner that i am using cos he said i can :P cant wait,

what else should he be checking? And how long does it usually take?

what are good air/fuel numbers when tunin a turbo b16a? partial throttle and WOT.

And my final question is, on the VAFC which is partial throttle and which is WOT? high and low?

Thanks Matt

A good tuner will use a wdie band.Tha is the only way to get a correct A/F ratio.As far as a stoich mixture,it will depnd on your setup.

on any turbo setup id like to be a bit richer than stoich 12.5s are good
