I always read about people getting a tune on their car but I was wondering what a tune would do if your car isn't turbo'd? What would a tune do for me? I got a 96 Civic hatchback with a JDM B18C1 engine swapped in.

Thanks

 

stock motor or are there simple bolt ons. (I/H/E) ??

 

Aem short ram, Megan headers, mugen twin loop. I was thinking of a skunk2 intake manifold but not sure if it's worth it?

 

You're not going to like this answer, but you need to do more research. I could write paragraphs explaining the point of tuning, the benefits of it, and the risks of not tuning, but you could get a lot of the same information with an hour of Google searching and reading.

The short answer is: if the engine is nearly stock, you're fine. If you hear detonation, you're not fine.

 

Alright cool

I'm assuming my engine is nearly stock since I haven't touched any of the internals and the engine isn't acting funny. So I should be good without a tune for the time being?

 

As long as youre running the ECU for the motor, youre good. FYI. I spent $400 for a 10 hp when I had my H22 Euro-r tuned.

 

Anytime you change a part from the factory to aftermarket
(eg. a header or intake, or cams and valvetrain)
the engine has the opportunity to make more power..
and since the flow characteristics are altered,
the ignition timing, fuel curve and timing need to dialed in.
For Short that is...

If you're changing the intake to a single stage or getting cams, you should retune. Headers and cold air intake won't affect it much.
