I don't know anything about the auto tune feature on EFIlive... can someone point me to a good tutorial? From what I understand it creates new tables for timing and V.E based on my engine... I have only ever used the tune tool to reflash my pcm for my v8 swap. I have played around with the MAF tables since I reused my v6 MAF.... but that is the only experience I have. I'd like to make good use out of the tool.
