I'm having the same problem on my new computer. I believe it as to do with logworks software. I can't get logworks to act right which I believe has to work to datalog the wideband into BE.
Go to the datalog tab and make sure the wideband is checked in the PIDS display. I assume it is because its displayed on the dash. Its been too long since I've messed with BE I don't remember anything else.
Well IDK. If i put it on the MP3 the rotor pack gave up at 2 passes down the quarter mile. I looked at a blower here with my old rotors and there was a black coupler on it. I think I put it in a blower that went on a Marauder. I think it would be fine. If I remember right it had a nice tight fit.
The early model MP cut off the back of the blower and attached a plate with the big smiley opening. I had the bearing bosses fracture and had Embry Machine fix one then the other side broke. I lucked on a AR kit and never looked back.
I don't recall the namings but the 1st iteration of the MPX was a modified stock case, which I believe turned out to have case problems at the back bearings. At least mine did :). So then MP cast a whole new case for the final MPX product.
I think you are referring to the MP S port which is a modified early blower if i recall right and the MPX is a whole new casting. the MPX would be the greater blower.
I did't do any searching so I may be wrong on the names.
What Mikey said. I also saw the NGK wires but didn't like the coil pack end but now dont see them on rock auto now to see if maybe you can just put the stock ends on them.
