so, im looking into upgrading my ignition setup in my civic b18c. its already got I/H/E and i got it tuned (mainly for better gas millage since the b18 is JDM) what are some recommendations when it comes to this? or is it unnecessary? keep in mind im not wanting/expecting big hp gains n stuff, i just want to get the most i can out of what i already have, efficiently. any feedback is appreciated
