Sure
But it may be lengthy and i am probably gonna step on a few toes and piss a few people off , but here goes. For less then $100 bucks more then the PC3 you could have a bazzaz which is a ecu that controls all 8 injectors. If you are paying a tuner anyway to tune the PC3 he will tune the bazzaz for the same amount and it is a superior system. You do not have to have the wideband corrector , the bazzaz will run off a map just like the PC3. But if you "choose" to continue modding your bike you could buy the wideband and eliminate the tuners. Meaning you change cams and the stroke of a laptop key and the corrections will be calculated throughout the whole map. Ive seen on several threads where people say the bazzaz is to much for me , i only have a exhaust. A bone stock Hayabusa would benefit from a bazzaz , factories have EPA standards they have to tune to .... they are NOT optimum comming off the showroom floor like most think , you could dyno a bone stock busa ... then simply put a bazzaz on it and tune it and get more power. My point being and why you should consider a bazzaz is that for the prices you are paying , you could ALMOST have a bazzaz and a wideband and say goodbye to costly tuners. If you change something on your bike even as simple as a air filter , a new map is required for best performance ... this ECU does all the work for you and is super user friendly. You should research the bazzaz unit before you spend the money on a oldschool PC3. If you would thumb through the software on a bazzaz unit you would be amazed.
