Raise your Closed loop enable temp to 150C. Then as you are looking at your VE and Spark tables your vehicle should idle in a cell or two around 800RPM and 35-50Kpa. So make the 400, 800, 1200 and 35-50Kpa all the same number and adjust that number until you get a good stable idle at the appropriate speed for your cam, as close to stoich as possible. I say that last part as some engines will not at all like to idle well at what appears to be stoich. As far as adding VE1 and VE2, I have not had to do that with any of mine as I have '7427s, but I think it is as simple as just adding the single column values to each column of the main table.
