Tomei P.M.B.C. Sensor- S13 SR20DET

[Mikester]

WHen I was in Okinawa and had my 180 tuned, IIRC there was a little box on the driver's side shock tower that the tuner clipped the connector & shorted (looped) the 2 big wires coming out of it together... He said something (in Japenglish) with respect to the fuel pump, flow etc. I came across this on FRSport, and I wonder if it performs the same function: Tomei P.M.B.C. Sensor - Nissan S13 SR20DET (http://www.frsport.com/Tomei-P-M-B-C--Sensor---Nissan-S13-SR20DET_p_54451.html?gclid=CO_GldG7krMCFS-RPAodkFoAUw)

If so, where does it go, if anywhere on a USDM S13? Or is this particular piece only applicable to JDM cars that originally came with SR's?

Thanks.

does is jump the relay for the fuel pump so that its always on? thats the only thing I'v heard or jumping together and having anything to do with fuel

I believe that's what it does... But the fuel pump relay on a USDM 240 is in the fuse box so again I am not sure if it applies to US S13's.

hmmm ya i would really like to know, i've recently encountered a leaning out issue. seems like a cheap fix. do you have any pics of it installed?

[Mikester]

Just checked my stash of old 180 pics... Don't have a shot of it. On an RHD car, It sits to the right of the MC on the aft shock tower- pretty much where the cruise control bellows sits on a USDM S13.

I encountered this on frsport once before and was curious about it as well but I never followed through with it since I wasn't sure where it needed to be plugged in.

Finally got the answer from one of my Okinawa buds... Pretty much what I suspected. Variable pumps (hence Pump Modulation Bypass Connector) are for JDM turbo cars, so on a USDM 240 that was never turbo, there is nothing to bypass.
