Sun, 31 October 2004 22:17 tyottsoarer, you want to intercept the wire called PIM on the loom (usually light green or light green/red trace). Hedgehog, An FCD never takes the ECU into "further mapping", it's not about that. It simply clamps the output voltage of the MAP sensor or AFM so it cant go above (or below) a preset voltage. As boost passes this preset point (say 14 psi) the ECU will keep supplying fuel for this level. On most cars tuning is OK because things are already a little rich by default and as the exta boost raises fuel pressure the injectors pass more fuel for a given opening time, thus keeping an upward trend in fuel delivery. Clearly, its a little hit and miss and things can be made better with a rising rate fuel pressure reg. But the important thing to remember is that an FCD "clamps" the ECU at what it thinks is a safe level, it does not unlock any higher tuning maps.... [Report message to a moderator]
