I'm afraid we are getting off track here, but my point was I wouldn't want to use the offset table of that injector like you posted. You are wanting to input the value at whatever his idle voltage is, yet the XFI thinks that value you input is NOT at typical idle voltage but at 12v. If you do it like I posted and adjust that value and get the idle A/F as close as you can, your VE numbers will be close to accurate. The resolution of that value is a tenth (1.1ms, 1.0ms, 0.9ms, etc..) so you are only going to get it so close.
