I've not bothered even attempting to deliberately unlock the Odyssey engineers. Have the 2 who are got by flying Apex and doing ground CZs, I think that is all, so far.
I've picked up a handful of OP, 2 SDP, 4 SC by just playing and having the right port at the time with 'useful' data. I'm not going to relog if I find something useful, but that is just me.
But, having done a lot of foot-work (until Update 7, I've not done any on-foot since it dropped) and picked mission reward materials, as well as mission destinations, have picked up enough mats to have 3 suits at G4 and 3 weapons the same. I can do High surface CZs with this setup pretty easily, will no doubt add 'engineering' at some point, but I don't know when.
