d16y8 tune up

Adding an aftermarket ECU will allow you to tweak the mapping, which will make good gains. HONDATA is used quite a lot on the petrol engine VTEC's but not sure about the D16Y8 personally. I would expect anything to change the mapping will net you a 20-30% power gain.

Next upgrade will be fuelling and turbo, but this starts to get expensive but you will often see around a 50% power gain from these mods, before you need to start upgrading the engine internals.
