G5 ISO 4/2 setting?

PR3CI5N · 09-30-2013, 01:49 PM

Have a N54 and I was curious as to what the advantages/disadvantages are of running 4/2 and having target boost run through the tune rather than the DME? I thought ISO already controlled the boost over the DME.

I believe you would want to run the DME controlled unless you are FBO on log log log...DME gives a lot of input in making decisions about what boost to run.

You would enable that feature if you want to run less boost than the flash tuning is programmed for. Most will not want to enable it.
