i dont think youll have any problems finding help when it comes to tuning (no matter how rare your engine choice is). Quite a few of us are really into getting the most out of a build through straight computer tuning, and then FI comes as second nature to an even larger group. Dont hesitate to ask questions, we're here for ya.
if you havent worked with a honda before, youll be glad to know that there are plenty of choices for tuning outside of the normal MegaSquirt, FAST and AEM. A couple are free, and most are cheaper than the alternatives with even BETTER results.
