Adding the Dil MAV on a JJ

[jstrang]

My JJ did not come with the Mav. It is turning 5 this month. I added it a couple of years ago. I love being able to turn of the adv for deco and for photography. I like the adv on the JJ but found it would fire a little too easily when I didn’t want it to - like taking a picture
- or on deco I’ll just add O2 as I go up.

I hardly ever use the actual manual add feature.

It seems strange that an almost contrived failure mode mandates the requirement for the dil MAV, but no need under CE for a BOV and factory GF lo has to be 30 to teach on it to retain CE status AFAIK.
