    Fmu

    Got this FMU today it's a SPA TURBO 6:1. I can adjust the fuel pressure also, the guy told me it was a new brand. I'm going to install it tomorrow and a fuel pressure gauge.



    I found this howto if anyone needed some help on installing a FMU.

            I got the BEGI one myslef and will be installing it ove the weekend. Does anyone know where the best place to install the fuel pressure gauge is? It has to be seeing the same pressure as what the injectors are getting, right?

            while you're out there, you might as well adjust your air/fuel ratio by smell... and your tire pressure by ride height

                That would be before or after an aftermarket fpr?

                  Before. It's between the RRFPR and the rail's return line outlet.

                      With that setup I have a 3:1 ratio. Beyond that you will running very rich.

                        You think you need it on a non-turbo car.

                        I have a Beji ARRFPR for the BBT28R set up, I am trying to get going.
