What's more important..your datsun or your marraige...just kidding

. I too suggest using the computer, as the carburation option may be more costly and time consuming. I'm guessing
it's the time-consuming part that has the potential to cause harm to the aforementioned..
The Computer install is almost dead easy, especially if you have a full loom. I can scan and send you wiring diags that will help. And it will run quite smoothly, it's not 100% because
you won't have a speed sensor, which in my experience makes it play up a little. But the associated symptoms with that are fully bareable.
Just think of the ease of turning the key and the engine starting in less than a second..no more choke..less swearing..it's got to be good for your marraige. Definitely go for engine/
loom/computer option. Otherwise you are heading into unchartered waters.

ps. I've installed 2x CA18's 1xDE and 1xDET.
