whats the point?? really? making something that you can buy already? all that effort.the likes of apexi power fc will out do anthing you can make by fucking round with a stock ecu, and plenty of places can tune it.
why why why...lol
if thats what you wanna do tho dude then carry on.... good luck
the features the stock ecu has are much better then the likes of pfc etc. For example you can expand the stock map and becasue eveyrthing is happeing in the stock ecu the signals etc will also be faster. There are gtr's running on stock r32 ecus with excess of 700bhp and hondas running turbos with over 400bhp. There is a reason for this as the stock ecu is better and faster then most piggybacks and standalones.
