I have a wet Zex in my Z28. I've been using a Hypertech PP III for 2 years now and I want to keep using it (incl. the tuning part)so I got a MSD Digital 6 Plus but I'm having my doubts about combining all 3 things!

For instance, how does the MSD know when I'm using nitrous and when I'm not?
The Hypertech is advancing the ignition but that's a no-no combined with nitrous, so the MSD should only `overrule´ the Hypertech when nitrous is used, correct??

I hope someone can advise me what to do. Thanks!
