Summary

00:00 - Shred Culture has asked, is there a reason why HPTuners uses equivalence ratio instead of lambda? Equivalence ratio is a technique or a way of representing air/fuel ratio that is very very common with factory calibration engineers.
00:16 So this is common when we are reflashing aftermarket ECUs.
00:21 Personal preference, I'm guessing, there's no real problem there, as long as we understand what equivalence ratio is and how we can easily convert to lambda or air/fuel ratio so we've got something that we can understand.
