I have a R32 GTS-t that I swapped for a RB25DET. I have in my possession a RB20DET AP engeenering edition Power FC with the commander. I installed the optional boost controller but I would like to know how to feed the the boost control kit. On the r32 gts there is no solonoid so how I hook up the wiring ,,,, Here is some thread about my probleme. I know that the R32 PFC has no pinout for the vtc but thats not a problem , I will install a RPM window switch to run the VTC. My problem is in the installation of the boost control kit on the R32 Powerfc. Does anybody could help a litle Canadian ?

Here is some link:

Here are some pics of my car and my project ( its the red r32 with gold gravity's rims )

you need to find pin 25 on the ECU loom

pin 25 on the RB25/RB20 should be "wastegate control" or "wastegate solenoid"

on your FC the pin will be there, but on the loom itself there wont be a wire

so youll have to run this wire to the engine bay

then install the PFC boost kit solenoid in the same place

run the wire from pin25 to ground on the boost kit solenoid (black wire)

then source 12v from anywhere and run it to the boost solenoid (red wire)

The PFC will switch ground on wire 25 to make the solenoid open/close at run time to control boost

so its essential you get have wire 25 and 12v to the boost solenloid to make it work

THANKS Paul!!!!!! SO just to be sure at 100% , that meen that I need to cut the 2 wires that come with the boost control harness to replace them with the pin 25 signal AND a 12V from anywhere and hook them up on the solenoid?

Thats what we call a FAST answer !

Yep

I looked it up and to confirm pin 25 on the RB20 wiring loom or Power FC is the switching ground wire

I was also going to wire my Apexi Power FC boost control kit tonight to my AP engineering RB20 power fc but plans just changed as my tuner said he will be using a different EBC

Good luck :P

Thanks !

And by the way , I'm I need to hook up the pin 57 and 54 same if I now have a RB25DET ? The throttle body is different on the RB25 so ,, is it very important or I need to install a throttle body of RB20DET to make it work right ?

    • oh they were with that motor, you need to remove the engine to change the spark plugs (don't have to, but it does make it easier)
    • I certainly fall into the annoyed camp, but glad to hear that if it's happening at low boost then I'm not likely going to blow a turbo and end up with metal shards in my oil. Just feels like it prevents me from really driving it without hesitation and "peak" performance. Wonder if it's the VCAM, it did an impressive job of shifting the torque curve and faster spool, but maybe now it's "too fast" and there's too much air for how open the throttle is.  Based on some other threads, will also do some reading on synchronizing the actuators. They are the default actuators that come on the Garrett's and I would think they would be set the same coming from the factory, but if the turbos don't actually work exactly the same way at the same time as previously mentioned, it would be worth making sure the actuators are actuating together properly
    • I went down this rabbit hole before, ended up sourcing a motor from the UK (I'm in Japan) which also didn't function correctly. With the original motor, I disassembled it and reassembled it and it works somewhat, sometimes. What I could deduce from all my screwing around is that there is calibration of the gears on the inside of the motor and two ramps on the main gear which activate switches that operate the motor and move the sunroof either to retract into the roof or tilt. Where I got stuck was that, it seemed in my case that one or both of the switches that are activated by the ramp on the gear did not always activate and thus the motor did not move, causing it to sometimes not retract or tilt (apologies, I've forgotten which way it didn't work.).  Of course this part is discontinued at Nissan now, it's the same part in the S15 but no other models. I also contacted the manufacturer of the component for schematics - forgot the name, they're based in Gifu - but they declined to share the information due to being bound by an NDA, sadly. Looking through my pictures now, it seems I last had a crack at this in 2022. See, I so kindly wrote "open" and "close" next to the switches. If you figure it out, please do tell me. Those little switches, with the red buttons may need to be replaced.
    • It says 300ZX, does that make it an Aus delivered car? Funny how back in the day I just couldn't care less about Z32's and these days I am just in love with them. Back when Nissan was into pushing the envelope. 🤣
