Summary

00:00 - Alfonso has asked with a good air fuel ratio target, is the auto tune feature a good option? Yeah it can really be a great feature and we're seeing most aftermarket ECUs now come with auto tune functionality.
00:13 It's a good sales point, particularly for novice tuners, can help them get their ECU tuned quicker.
00:21 What I find though is that a lot of people put a little bit too much emphasis on the auto tune function and just like anything, it's a case of garbage in, garbage out.
00:31 If we don't understand how to set the feature up, how to drive the car, and also shoot for the correct air fuel ratio targets in the first place, we're probably going to get a sub par result.
00:41 And personally even with ECUs that have auto tune functionality, more often that not I find that I actually hand tune the fuel table anyway.
00:50 I normally get a better result in less time.
00:53 So that's just something to keep in mind.
00:55 But if you understand the principles behind the feature, yes it can definitely be useful.
