Yes, I guarantee you can do it! Much less capable men than yourself have succeeded. I can put you in touch with 4 dudes in Auckland with MS experience, all of which are good blokes. I doubt you will need it though. There is tonnes of documentation available, too much IMO.
MS1 will be fine. There are quite a few MS1 FE3T engines out there. At low boost on 440cc injectors you should be OK with MS1. MS2 will work better though for idle and overall accuracy of control. Given that you are the rangi mod man himself though, you are right, MS1 is a good choice. It does have some benefits over MS2 also.
Whether it's ms1 or ms2, spend the extra on the V3.0 board. It is worth it IMO, though, again, lots of people are happy with the 2.2 unit.
The key thing is that your wiring is good. No twisted together wires!! No engine management OEM or otherwise can be rangily done ;-)
ROTFL : I just google image searched "maori wiring" hoping for twisted together wires and the first image it shows is this :

None of this on your install :
If you want it to go extra smoothly, you have to pay close attention to grounding. One of the MS designs worst flaws IMO is that it has a single connected ground system. This means to keep electrical noise low, your power and ground wires need to be bigger than they otherwise would have to be. They should go straight to the battery via a fuse and relay from the key for power, and straight to the engines head for ground. If you are careful with the wiring, you will have no problems at all :-)
I here by promise to give you 1 on 1 support if you decide to go through with it.
Other options on low boost like that are BPT electricals and 4G63 electricals. Either will work ok, but you will have a great time doing your first MS install :-) It's very satisfying!

Go with that. If you decide you want a smoother idle or more power and bigger injectors, you can upgrade to MS2 pretty easily.
