Does anyone know anything about this unit? I recently started putting together a turbo setup for the H and the FMU was given to me for free. I know its not adjustable so I'm assuming it operates on a fixed A/F ratio. Does anyone know what that is? Are they junk? I'm just trying to put something on the car that will help it run safely until I get ahold of the Hondata S300 program to put onto a P28 ECU.
