imo, only a dyno can do that entirely accurately. although by using a g-meter (or just a time/distance measurement) on a repeatable stretch of road to measure acceleration can give you some idea
Although experience of a very similar spec engine can do that
Im sure most of the guys on here mapping cossies for example, know full well what AFR's are going to work on which spec without needing the dyno again and can get ridiculously close to ideal results just from experience/AFR
i agree - if the spec. is known in detail.
but i suspect the topic starter is asking as he wants to do it himself and doesn't have that experience to rely on
