How do you sync ITBs with megasquirt?

How do you sync ITBs with megasquirt? I have dual 48 cb performace TBs. The vacuum signal is tee'd and goes to MS pressure sensor and my FPR. If I separate and unhook them from MS to connect to a manometer it won't idle. Do you have to create a separate MSQ to make it idle without a vacuum signal? Or leave one bank connected to MS? Newb question but I was wondering how you do it.

Most people use a unisyn or syncrometer. If you want to use a vacuum manometer you will need to add tee fittings in your vac lines. You also need a vacuum line per throat if you want to do it that way, the existing fitting in each CB throttle body can't be used for syncing side to side.

Here is a video I made showing various tools for sync;

I do just like dual IDF's and use a unisync.
