FMU is not what you need, that is a boost dependant fuel pressure riser for a turbo setup. It raises fuel pressure a certain amount for every psi of boost. You would need something like a hondata or uberdata that can be tuned on a dyno for your specific setup. Piggyback ECU chips won't be enough. You need something tunable so detonation doesn't occur inside your freshly built motor, and put a hole in a piston.
