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.

    • After using a protractor for an actually accurate assessment of what is required,  and by NOT using my uncalibrated eyeball I worked out I need a 25° silicone bend from the TB ro the MAF, but, my choice was either a 30° or a 23° (23° is a weird spec), so I grabbed the 23° one from Raceworks I also grabbed 1mtr of 3" straight from Just Jap, I needed 350mm, but they only had 300mm, or 1mtr lengths....meh Also ordered a 1/2" hose bulkhead fitting from fleabay, this has a smoothish mushroom looking head (they are designed for below the water line of boats) that will fit inside the bend, the hose bit and threaded bit looks to long, but nothing that a hacksaw cannot fix if required, the hose will then just get jamed on the threaded bit up to the retaining nut Fingers crossed and the unsightly amount of hose clamps will be reduced down to 4 once all the parts arrive 
    • Oil change does not trigger code 21. Code 21 is for coilpacks primary side connection. You can try to clear the code with a battery disconnect, hold down the brake pedal to drain capacitors through the brake lights with the ignition on for 10-15 seconds before you reconnect the battery. I have seen R35 coil conversion permanently cause this code with no ill effects so it might be the resistance it wants to see isn't quite right on one or more coilpacks. Could be inside the ECU, could be the harness, could be a coil. You can test it all if you want or just ignore until the car actually starts misfiring.
    • I forgot you have a Nistune ECU. Use Nistune to do all the tests I mentioned instead of faffing with 30+ year old electrical connectors. You can read MAF volts off that too, there are reference values in the service manual to tell you roughly what it should be in different conditions.
    • No. I think it might be the AFM. Hence the use of the terms "swaptronics", which implies the use of swapping out electronics for the purpose of diagnosis. It's about the only way to prove that a small/niggling/whatever problem with an AFM or a CAS or similar is actually caused by that AFM/CAS/whatever. A known good item swapped in that still gives the same problem is likely to be caused somewhere else. They're all the same. Spraying AFMs with cleaner is an each way bet between cleaning it and f**king it.
    • Oh wow! This might actually work amazingly. Do you know the ratio of the diff? I was told the only thing you need to make sure of is if the front & rear diff ratios are the same. Ours is a 4.083 Thanks!
