I'm actually not sure if my OE EKPM was faulty, after finding I also had an HPFP failure (which was a new out-of-box unit). Car kept going into Limp Mode on recent freeway travel. Probably lucky that I got home.
However, I'm thrilled to have installed this unit in order to gain some headroom and subtract possible power supply concerns from my fuel-supply diagnosing. Instructions were succinct, install was straight-forward and pretty easy (I had the EKP and the HPFP done inside of three hours). Company was also immediately responsive and helpful for the few questions I DID have. It's nice to do business with folks like this. I was also a bit concerned about fitment since this was going into an E88 and they are a bit weird compared to the other N54/55 cars. No issues at all though. Clears the door card with plenty of room for the fan to work. I'm super happy with the whole thing.
My fuel mods include:
ET3 Stg4 EKPM3 w/12ga copper wire 30a fuse at battery and 30a breaker at module
Single PR Bucketed Walbro 274 w/upgraded harness
New OE Regulator assembly
PR Quik-Connect Teflon fuel-line from tank
2-channel in-line E85 sensor pass-thru assembly
Radium Engineering in-line E85 fuel-filter
OE HPFP (to get the car on road while I wait for another replacement) w/ filter removed
Billet HPFP to Vac Pump plate
OE hard-line to injector rail
Still to install:
Radium Regulator/Pump (dual AEM pumps and 1:1 boost ref) assembly (if i need it)
PFS POD HPFP overdrive (if I need it)
