Are you going to be switching to the haltech flex fuel or does it output differently? Might be a cheaper alternative for sensors.

Would make sense that haltech ecu would use a haltech sensor.

Unfortunately, they aren't rated to support the 73psi fuel pressure the n54 runs at (pre HPFP). So no, we are using the more expensive one that is rated to run up to 150psi. The Haltech sensor would be used on a return line (no pressure) if the n54 had a return line
