I am planning my GTR R34 Haltech Platinum Pro Plug In install right now, do I still need the stock OEM Wastegate valve control solenoid valve?

The reason I am asking is because I no longer have this OEM valve since I have the HKS F-con V-pro and Trust Greddy Profec B at the moment.

It certainly wouldn't need it.

It gives you the option of using it if you want.

When you say I have the option of using the the factory Wastegate valve control solenoid, do I still need to purchase the Haltech boost control solenoid or can the ECU control the factory solenoid?

You can run either, but you already have a boost controller.

I would ditch the profec B and get the tuner to use the Haltech solenoid, or any other MAC valve in place of the stock solenoid.

Thanks man! I will be ditching Trust Greddy Profec B then.

Whats the best or correct way to hook up the Haltech/MAC Boost control solenoid valve?

Wire it to the stock wiring if it is still there. If not, 12v and a spare DPO on the Auxiliary plug on the rear of the Haltech.

I was going to say something smart like "with wire, doofus", but I realised that he may well have meant more to do with the hoses than the wires. And I thought, "Nah, let him find the answers himself. It's not as though the question doesn't get a new thread every 2 weeks".

    • There's restrictor pills in the stock boost control hoses. That's how they set the amount that was bled off and hence the "high" boost setting. The usual mod in the day was to remove it and send the "high" boost setting up to about 14 psi.
    • Thanks Duncan, that's the best info I've read. Furthermore after learning about the PCM programming side controlling the factory boost solenoid, the purpose of the solenoid is to "bleed" boost when pin 25 is earthed, thus allowing spring pressure in the wastegate actuator to overcome diaphragm boost pressure, thus closing or reducing the position of the wastegate flap creating more boost as the turbo is able to spin faster. It's pretty cool to see a designated Pill to do exactly this, would have liked to have seen it with a tiny filter over the end for those moments in vacuum.  The constant bleed pill has now been removed completely from the system and solenoid boost control has been restored once again.   Case closed 😂
    • The wideband reading is meaningless if it's not running. Why are you using shitty old sidefeeds on any engine, let alone a Neo? What manifold and fuel rail are you using to achieve that? Beyond that, can't help you with AEM stuff as I've never been their ECU/CAS combo.
    • Manual boost controllers (where a little of the boost was bled off) were quite common back in the day, because they were cheap and easy. Generally they had a manual adjustment screw rather than being fixed like yours. Down side is they always bleed boost, not just when you want them to so an electronic boost controller that uses a solenoid will have less lag.
    • Hello , im new here and i have A31 home build  RB25det neo stock eng / turbo  aem ems 2 blue connector  aem 3.5 map aem cas disk aem wideband connected to ecu  355 lph pump 550 nismo yellow injectors side feed aftermarket regulator  and won’t start with base aem tuner basic tune eventually flipped cas 180 degree so it triggers on correct stroke not in exhaust cycle  Now it won’t start Wideband reads 10 and 11 at lowest fuel setting  and will share calibrations soon for aem tuner i think something is wrong in aem tuner    please if you have any information, am very grateful
