I was wondering if a FMU with the stock ecu and bigger fuel line connections for increased fuel management for additional boost, could be an alternative instead of buying an expensive aftermarket ecu. Obviously I wouldn't be getting the benefit of rev. cut or a few other option but I don't care. I will soon be installing a full exhaust and intake(s) as my only mods. I know its a cheap bastard question, but I'm only cheap if it works safely, and properly.

Thanks

 

In short you can do this and people have done this, but is not recommended. When you upgrade your car you also have to tune the ignition maps, which a FMU will not do. An ecu like the Power FC is very versatile and you will never hve to replace it if you go non-sequential or single turbo.

 

There has been so many posts about this, and at least three last week. There is no point to a piggy-back fuel controller for the FD (other than the PFS PMC). The stock ecu runs rich enough for all of the bolt-ons at 10 psi. The problem is, you will have a difficult time controlling boost to 10 psi with a midpipe, so don't put one on.

As I've said many times before, if you can't afford to mod the car properly, then don't do it. At the least, spend the $400 for a used Pettit ecu, so at least you will have the fuel delivery if your boost creeps up to 13-14 psi.
