If you are running a factory toyota ECU there isnt really a lot of tuning that can be done.
Check that you have all your sensors hooked up. An exhaust will help too.
I take it that if youre running it without an exhaust you arent allowing it to heat up too much?
Part of the cold idle setup on the 4AG* is to run quite rich.
Also be careful - it is possible that when you shut down an engine without an exhaust that it can suck air in through the exhaust ports on shutdown which can cause rings to crack or worse...
