I was thinking about all the work that people go through in order to tune their ignition maps on things like chrome, AEM EMS and their Hondata systems, but I was wondering, if the computer automatically tries to advance or retard ignition timing until it knocks with the feedback of the knock sensor, then wouldn't manually setting the ignition maps be unnecessary? I heard that the AEM EMS has a function that can create ignition and I think fuel maps as well automatically when you first set it up, so I was wondering if it works strictly off of using the knock sensor for that and if it does, how does manually tuning the ignition maps after doing that improve performance. Is there a way for it to "auto" set the ignition maps aggressively?
