  5. Oil pressure sensor question

    what did you end up doing?

    I'm trying to get mine ready, I got a pressure sensor was just going to remove the factory one, (its just a switch) and install the 150 psi sensor in that hole, with the oil temp down in the spare port of the Greddy sump. 

     

    Hi Deano,
    I did exactly what Adam mentioned above, the factory sensor controls the light on the dash, and the aftermarket sensor which is controlled through the link is set at a minimum psi which when triggered depending on how long the pressure is wont let the engine rev high to damage it( limp mode)

    If you remove it then your tuner will set the up the new sensor to replace it, not to sure if the tuner can program it to do both, but since my engine was sitting for a while and it had a new turbo, we disabled the cas and turned it over to build oil pressure/until the dash light went out

     

    cheers

  6. Bosch 044 issue

    in Link G4

    Posted

    Found the issue, it was due to voltage drop, from 13.9 volts to 13.84v, when the twin electric fans, heater, lights where going it was running at 13.78 volts, dropped to 13.7v at its lowest and was affecting the fuel supply

  7. Nissan SR20DET IAC Valve issue

    Posted

    Hi all, noticed that my car has been running very rough on startup for a little bit, my auto sparky said that the iac valve has quit after 16 years, tried cleaning it and putting it back on. He mentioned that they can tune the vehicle without the iac valve, is this recommended?

    Any help is appreciated, I am waiting for s13 iac valves to come back into stock at efi solutions australia, but they wont have them in time before my tune is booked

    The 044's are fairly sensitive to cavitation and that can give them an erratic sound similar to what you have there.  Im not saying that is your problem, but something to consider.  They dont like to "suck" at all.  They typically need to be pressure feed by a lift pump or gravity fed by mounting below fuel level.  Definitely no filter on the suction side and the inlet hose needs to have little restriction.  Cavitation is usually worse as temps increase, so if it is quieter and more consistent on a cold morning and gets worse when the fuel or day  warms up then that would be a strong indication of cavitation.

    Hi Adam,

    Thanks for the reply, its feed by a new walbro 500hp pump, new fuel tank, new lines, fittings, new surge tank, as per the photo, which the only restriction I can think of is the 90 degree fitting coming out of the pump, which that braided hose connects to the fuel line
    New in- tank Walbro 500hp feeds the surge tank, bosch 044 is connect to the bottom port of the surge tank and the braided line connects to the factory fuel line, though to a NZKW inline billet fuel filter 35 micron, then to the fuel rail.

     

    Top 90 degree line into surge tank is from the in tank walbro
    Top 0 degree fitting in the side of the tank is the return to the fuel tank
    90 degree fitting in the face is the return from the fuel rail

    my only thoughts next would be to;
    1. Check the voltage of both pumps then replace the dash 6 fitting from the pump to the standard fuel line to a full flow fitting?
    2. Ive brought the billet LS1 alternator adapter to fit to my sr20det and replace the factory alternator(80-90amps) with a new LS1 alternator which is 140 amps, to help with the draw of the twin cooling fans and twin pumps, when the fans kick in the strain is quite bad.

    3. Borrow my mates pump and hook that in and see if I may have a defective pump

    Hi all,

    I brought this Bosch 044 from DSR Turbo in 2012, had it sitting away in dry storage while I put the car on hold. now I have it all running the pumps running it does not sound consistent when running, I brought it from DSR turbo because I knew it would be a genuine pump, below is the video of the pump, from the sound does it sound defective to you or is it supposed to sound like that?

    Any help is appreciated, I would like to know so I can replace it before I heard to the dyno after the covid lockdown is over

    cheers

  11. Oil pressure sensor question

    in Link G4

    Posted

    Hi there, I brought a link g4 plugin for my rps13 sr20det street car, and wish to install a 150psi honeywell oil pressure sensor as extra insurance to protect my motor, will this replace the factory oil pressure sensor in my block? Or do I need to run both?

     

    I have a custom oil block adapter fitted to my engine which does not have any ports to fit the factory sensor, the attached photo shows my aftermarket sandwich block with the factory sensor, there is little room for extra sensor to fit in the other port that's blocked

    Thanks in advance!

  12. Nissan Silvia Ecu case alternative

    in G4+

    Posted

    Hi all,

    I was originally going to buy a d-jetro power fc for rps13 180x running a s2 sr20det non vvl, but i came to my senses and brought a  link g4+ plug in from NZEFI, unfortunately i sold my ecu and have not been able to find another as they aren't for sale separately from engine packages, My question is are there any other nissan ecu cases that will fit my link into, i see on trademe there is a rb25det manual turbo case for sale which i plan to purchase if the header plug is the same width and length, any other suggestions, i have asked around tuning shops but they give them back to the owners and wreckers wont hold onto ecu that old

     

    thanks in advance
