Is there a way to program/have programmed the ECU for a 94 Civic DX manual coupe for better MPG? Also, how do I get out of trial user status to post to the hondamarketplace?

 

I dont really know how much it would help to try a tune fro more mpg's. A good tune up would be more worth it. I think after 10 posts the trial user thing is done, it may be a certain amount of days, i cant remember.
