dude......sup with the caps?
1) you do not need an FMU with 450cc injectors. If you do, you will extremely run rich!!!!!!!! Think about it. If you have a D16 or B18 Honda engine, your stock injectors are rated 240cc. You have already increased the injector size by 210cc........ that is almost twice the rating of stock 240cc. On the "hack", the AFC is set on the negative side (lean side) because the 450cc injectors will dump too much fuel already. The best part is, on the negative side, the MAP sensor voltage signal is toned down thus preventing CEL/MIL. I honestly wouldnt combine the three: FMU, 255 LPH, and VAFC especially on low boost application. If you are going to boost high, disregard the FMU and the "hack" idea altogether. Also, the three of these combine is really overkill on low boost. I really dont even know where to start....... list more info. Start off with what engine do you have, boost goal, hp goal, mods....... gotta be more specific......
