Yep, I did exactly what you are planning with a smallport 4age.
Standard dissy system worked fine.
I actually replaced the ecu with a gze one, with matching injectors and map sensor... and then added an emanage.
Honestly, just get a second hand adaptronic or similar. For the effort of fucking around with an safc or emanage, it's not much more cost to go full stand alone, and the result is much more reliable and better all round.
