I do totally disagree that the vac line does not have to be connected to the regulator in the EZ especially.. it will run rich in most cases if you do not do this. If you switch it from not hooked up to hooked up then it will take time to learn out the areas where it was trying tune around the perssure differential. The more vac the engine makes the more this will be a problem.
I am saying this for the exact reason you are saying it "does not matter" so other people on the board that read this do it the right way and don't try to over think it... like you said if you wanted to know this then you would buy a tuning EFI system. In this case just follow the directions and don't think about it.
When I do things... especially EFI.. there is only one way to do things.. the right way. This is a clear cut right way to do things, so why would you do it any other way?

I wasn't speaking of the EZ. I've only done one of those, and it doesn't work for the combo (750 HP 494 Cammer Nascar twin throttle body engine). I made several changes to get the vacuum up, but being rich is not the issue...............
Again, we're just discussing your claim that the reference line must be used. I was speaking of all EFI, but even with the EZ Efi I'm not sure I agree. It's obvious many people have them running fine without it. Is it a good idea to help it self tune, apparently so. A "must"......... no. I have tuned too many EFI systems without it to agree.
It's all semantics. When you speak in absolutes you'll invite people to give examples that contradict what you're saying. If you said that the system is designed to have the reference line attached, and it helps the computer learn the tune much faster, I don't think that anyone would disagree with you. It's the absolutely "must have" wording that doesn't fly, because we have examples of that not being true.
