If you are having issues with idle, you need to properly scale the injector idle latency.
Try this for a starting point and adjust up/down to attain your desired results. Once the latency is sorted, you can fine tune with the fuel MAP tables. Also, do not get too caught up in Injector sizing on the injector offset setting.
For example, for my STI 800ccs (@ 3 bar), I have the injector scalling at 700cc and have adjusted the latency to facilitate.
Below might be a good baseline. Scalling you can start at around 820 - 850 cc. You can adjust scalling up and adjust lag time if this baseline works for you
voltage 7.99 /10.01/ 12.04/ 13.96/ 15.98
dead time 3.01/ 2.2/ 1.8 / 1.25 /.95
