Well after months of not having any responses I decided to install one anyway. The ECTED max is the new version they have out that fixed the quirks that the old ecteds had. I don't engage mine often, but the limited slip is TIGHT! I would highly recommend it in the front end but like with any other locker options, stick with a posilock set up to ensure maximum versatility. I'm running vacuum and switching to tj shafts this weekend and chromos by winter.
Luck Favours The Prepared
