I'm messing around with the z31 rom and I was wondering how you guys are tuning the maps for the different rpm/load points. I know on the dyno you can only take the car through a limited set of load and rpm points to get the afr readings. How do you go about correcting the rest of the map? Educated guesses? Also, when you swap in the z32 afm do you redo all the maps or do you simply change the K or VQ maps? I'm mostly interested in the steps that you take to get your maps right. I know the ecus are not the same but I'm sure the way they work is pretty close. I've got a wideband kit and a rom burner so I'm all set as soon as I fix my engine. Just looking for any tips you dont mind sharing.
