Sorry for my stupidity but I was wanting to see if anyone could help explain the basics of upgrading ECU's or chipping. I've always seen ECU upgrades for sale on ebay but I just thought they were overated and cheap ripoffs. I have a '95 Prelude SE and I've advanced the timing (which made a good improvement) and have I/H/E. I would like to do some more mods and was wondering if an ECU or whatever would be a good next step. Thanks
