I have my ego helping at idle alittle too. It was the easiest way to smooth out the idle. For me on the ve table there was a big difference between 53 and 54. Im not talking about the ve table under constants but the ve table under tuning. When I changed the constance ve table to get the number to change on the tunning ve the afr at idle went from like 13.6:1 to 15:1. So I used the ego to help alittle. Thats what it is for right?
