PC3 USB

[BusaNation]

Interesting viewpoint Busgo, one that I can relate to.

Everything I've read indicates that the ECU is indeed self adjusting. But it's keeping the AFR quite high. Is this too lean? I don't really know, but I don't want to find out the hard way and have to start giving away fat cheques to get the head taken off and new valves etc. haha. Getting a $350 power commander (delivered) seems like a good insurance policy.

I'm new to the game of power commanders, but as Simmo said the map for the '08 with full yoshi system is vicious.

Moving on from electrics, pulling that heavy stock system off was the best thing I could have done for the bike. Apart from now not being stealthy quiet, the bike does everything better from my perspective. Handling, exhaust note, looks, power. I enjoy the bonuses in that order.

It is not just a matter of spending $350 for a USB. to optimize the PC, u need dyno time 2-3 hours that cost$$$$$$ and you need more importantly a guy who knows how to tune. A usb is pointless if you just plug and play and load up a map you think will work for your set-up, that scenario you are not ultilizing anything and you hope it works the map you upload into the bike., THE tuner is key! All tuners shold anyway the 1st thing they do is check your A/F ratio, this is a starting point, the a/f should be a straight line and for a busa should be in the 14.1-14.7 range A/f. -Cheers Duane
