Definitely take out any rising rate FPR. However, regardless of where you set the Required Fuel, they'll need the same pulse width. Consider going to hi res code for more resolution.

Why would you idle at 12:1, you have full control of your fuel map

In the two local cars I did here, we have 550s idling perfectly smooth over 14:1, both on high res 10g.

Here is my map... u can check the few values you are looking for in there. Take everything in there with a grain of salt though (startup enrichment needs adjusting, my fuel/ignition maps, my timing (cas and matched timing)) etc.... don't just plug and play it... just use it for some small references.

rx7 550s happily run on my car with HiRes (ran ok on 029y also), HiRes rocked it though.
