as far as feuling goes, will a reflash that expands the range of the map sensor and some larger injectors and a fuel pump be fine, or will secondary injectors be necessary?
We are presently waiting for Petrik to successfully flash the ECU from the B-King, being that it is different from the '08 Busa ECU. Even after that is done, it is unclear whether or not the internal software can be manipulated to accomplish this.
The problem is that the B-King ECU shuts down the bottom injectors as the upper injectors come on, around 8,000 rpm. You cannot run any more fuel even with 2 powercommanders because the factory fueling shuts down the primaries, and a PC cannot turn them back on. For that reason, our powercommander will be connected to the upper injectors to get enough fuel while on boost. Once our map is done, we will have somewhat of an idea as to how much fuel is left, and how much more boost could be made with the stock injectors.
Right now there are no larger injectors that we know of that will fit in the factory rail . . . to make the big horsepower on this bike you will definately need to run piggybacks at this time!:cry:
From what we are seeing on the dyno, it looks like we will be able to make over 300 RWHP with the stock fuel system by taking control of all eight injectors . . . of course, a spacer plate, some valve springs and stainless steel valves will be the way to go . . .
Im hoping to find the limit of stock injectors with a 1:1 regulator on my bike using ecu only. 2 different guys using boost fuel on 08 busas have made 330 hp using ecu boost fuel tuning and a fmu, and had plenty of duty cycle left. hopefully can get 300 on a 1:1 setup as well.
Just wondering if a video clip will be available....I'd like to know how loud the exhaust is.
Where is the oil cooler?
