Message	The NA FPC only uses one digital control line to switch from low speed to high speed. Low speed is about 75% duty cycle and with a TT fuel pump it may cause the fuel pressure at idle to be slightly elevated. The TT FPC at idle will only run about 60% duty which keeps the regulator from being overrun. You need to keep the ECU and FPC matched to each other. Additionally, if you do an NA-TT conversion you will need to run the extra control line from the ECU to the FPC as the NA harnesses do not have this line built into them. Enthusiasts soon understand each other. --W. Irving. Are you an enthusiast? If you are out to describe the truth, leave elegance to the tailor. Albert Einstein
