Here is a spreadsheet I setup off a fuel map dustinb sent me about a year ago. He was (is?) running 440cc's and an AEM 2bar. I basically used a percentage to calculate the duty cycle on my 550cc's. Just enter your injector size in the green cells and it will give you a VERY approximate fuel map to work from.
Also, on your high idle, the AEM's default settings on the IAC duty cycle are really high. On my car it will idle at 700-800 with the IAC unpluged. So I used that as my base for the IAC table (800rpm = 0%) and just swagged a curve in from there.
