I wish my thing was that easy to tune.
The issues with Honda engines, mostly the high end B-series engines, is that they're already so good it's hard to soup them up without spending boat loads of money. This is why turbocharging or even supercharging is so popular because it's a better bang for the buck then trying to soup up an engine naturally aspirated.
I think your car is easily tunable since it is ODB2 but the changes you'll see won't be as great since your car is not force inducted.
