True, but both sound like one heck of a challenge lol.

Are you saying I can have the ECU computer reprogrammed for lean burn and to somehow make the manual tranny work as an automatic?

A significantly greater than 10% improvement for just one mod. wistfull look
The HCH1 also has a much smaller engine(1.3L) making much less power than your 1.7L...

You may be able to use Hondata to reflash your ECU and add in lean burn at cruise and alter shift points of your trans, which *could* gain you between 10 and 20 percent... an HX swap, while more involved, could gain you a little more...

The HX manual trans has better gearing than your auto does I imagine so the trans alone would get you something...
