Come on guys, what are you running? Andy, what are the FOM cars, particularly Nick's?
Nico, you say that the S4 chassis and S5 ECU are preferred but that does not compute. To put an S5 ECU in an S4 car you would have to change the body wiring harness plug (or the entire harness), and I can say from experience that that is a nightmare. Some of the individual wires don't even match up. Is this being done and how so? Otherwise, you are stuck w/ the S4 ECU. So, would an all-S5 not be better than an S4 w/ S4 ECU but S5 everything else?
