Hi guys, to give you a bit of background I have just purchased a Blitz SBC-DC Spec R, so runs the dual solenoid setup, for my rb25, steam pipe mani, 44mm gate.

Basically with the 44mm gate plumbed straight to vacuum, the car runs 15 psi consistently to limiter, however I tried to test with my blitz sbc setup as per the manual states.. and I'm having mega uncontrollable boost issues.

It will go from around 6-8 psi and then just go nuts to over 20 psi...

The SBC DC is almost like the ID3 with just a few less features, ive set everything on it to a minimum and also tried test driving the car with it turned off (so solenoids should be closed) but it seems like its still open and the gate is being held shut.

This is a pic of the setup below, please help.. I have drift prac this weekend and wanted to wind in a few extra psi...(as it's tuned for 19)

Pic below shows silicon tubing (id of around 5mm) running from boost pressure just after turbo elbow, into a T- Piece.

The t piece left side then runs to wastegate lower port to help diaphragm open, and the other to the "in port" of the dual solenoid, this then runs out of the "out port" to the top of the wastegate to keep it shut as per boost settings...

It just seems to be open all of the time, checked all wiring and it seems fine... also pulled solenoid unit apart and seems fine, no burnt out wires etc..

Is there something I'm simply missing?

Cheers.

    • Hey guys Long time lurker, I daily a nm35 stagea 250t rs four and I've had it for almost 2 years (very reliable 👌). Issues or just looking for information ill always find myself here having a read, so thought id join.  3inch stainless intake, pod filter, AM performance turbo dump pipe, 3inch hotdog, 3 and half inch stainless to 3 and half inch AM performance blast pipes. Bc racing coilovers. 18inch rims Hdi intercooler and trans cooler soon.  Here's my car
    • thanks for the advice on the box... i was thinking the 6 speed was better for cruising on the highway but on closer inspection and comparison the Rb 5 speed box was not too different...  So the choice is going to be the RB25 box... if I can save up and find one at the right price  
    • Thanks Matt, yes that's what i am aiming for. Just going to apply the right voltage and grounds to the dash connector. Hence my search for these pins... any chance you know if these pins are in the same spot as the ones on the S15 Dash connector? as mentioned above on page 8?
    • Yes, unfortunately that's the one. Signal was noisy to begin with; after driving once and looking back at the logs I saw pressure constantly swinging between 0-200psi, or staying at 0 randomly for a few seconds. There's a lot of good sensors that share the same look and feel, so don't presume they're all bad. I bought mine for 20$ off Amazon and I should have read the reviews prior, as it's clear they're junk.  I purchased a lowdollerr motorsports sensor.
