I already got one
^^^ This is a MAJOR issue with this swap. I am dealing with it now and it is not a cheap solution--especially if your "CEL" needs to be off to register the vehicle.
At the peril of making this tech... is there an answer? Is it the European ECU? As far as I can tell, the common M/T ECU from Oz is non-OBD.
I plan on doing this swap next year and have been anxiously awaiting. I'm one of those "can't be a CEL" people.
Yes, there is an OBDII manual transmission ECU from a Japanese 80 series with the H151F. 89661-60340. It is NOT CHEAP. I have it ordered out of Japan and am awaiting it's arrival to assist with the cluster of a project we have going here.
Of course, the working assumption is that all of the connectors will work from the US 80 series into the Japanese ECU. If not, wiring will have to occur. Again. Ugh. It is well over $2K for this ECU.

Jealous. That trans would work well behind my 1hdt. Go team no spark plugs. 
Well, they came stock behind your transmission but you would stilll need some type of engine management and integration system that the ECU enables seamlessly.
So here's my thought on the issue... Why hasn't anyone figured out the mA/voltage ranges (or whatever) that the ECU looks for signals. IE what are the signals on certain pinouts that make the ECU output a "working normally" condition.
May be a lot of engineering work but I'd be willing to bet someone could make a simple circuit board with one input that could output all the signals necessary to trick the ECU. I'd even be willing to wade through wiring diagrams and ladder logic (if available).
This seems much more cost effective and reliable than finding another ECU and just hoping it integrates with a NA system.

I put one behind my 1hd-t. Really woke it up and gained huge mileage!
30-40 man hours of wiring work at $125 an hour is about $4k more than just getting the ECU.
For just the transmission job?! The transmission logic/call outs can't be that complicated.
all I'm suggesting is that an electrical engineer could probably develop something pretty easily that could possibly make the ECU issue simpler and non invasive to the rest of the vehicles systems....
It's not just the transmission job. You are also integrating the entire engine management as well.
Yes, Aus is non OBD. Mine's an 1995. It's now running an LS2 anyway so I have the old Toyota ECU gathering duct. Free plus post if anyone wants it....
how huge?
gnarlynick, wanna wheel? check out ghostwheelers forum on here. I'm in red deer. Runs vary from easy to extremely technical but its a highly selective, informal group. The right people and the right rigs make for very good experiences in spite of any circumstances.. If your interested post up on our next run.
I'd be quite interested in that as I'm planning a conversion down the road. I'll also post my findings for all to learn from. Could you PM me so I can send you some money for post?
You have an OBDII system. The OBD-less ECU is not going to work and you are still going to get a CEL.
