Hey guys, I am new to these forums, mainly do subaru stuff. But I have a question which is mainly aimed at all the guys out there using power fc's. I have one for my car, liberty rs, and I am running a Z32 afm at the moment. But I was wondering if you were able to elimate the use of the AFM with the PFC? I know that there was a special kind of PFC that was made, that didn't use an AFM, but pretty sure they were only made for a skyline, no subaru's.

But my question is, are you able to use a Air flow Converter, or Super air flow converter in conjuction with the PFC to get rid of the AFM?

Thanks in advance,

Mitch

You still need to have a signal coming in to bend. Where are you going to get you air flow reference from then? Why have a signal bender if you have a programmable ecu?

Need afm for normal pfc. Not need one for d-jetro.

If you search there is craploads of info on this topic.

^^ As he said you will still need a signal to tell the pfc how much air is coming to the engine, the AFC and the PFC are only piggy back computers as where the PFC is a stand alone ecu so running a PFC and SAFC will only interfere with each other

you could run an safc and powerfc if you wanted but it wont achieve much

the safc wont allow you to ditch the afm to run a map sensor

have a look for the hks vein pressure converter, see if you can get that for your car

can you run two afms. i think with a safc you can have two inputs and convert it to one output then feed that signal into the pfc. or is the powerfc able to do this conversion aswell.

yeah you need the safc to run two afms on a single AFM powerfc (or stock ecu conincedently)

    • I havent bought a manual cover for the dash yet and no cluster change, won't bother me too much, I just need to get that auto box gone, manual in! I miss my manual. 🤪. We started last weekend and managed to get the box out. Planning to start putting it in this weekend and then order a single piece tail. We were super careful to take time and not damage anything. It's my first time working under the car.  With my S15 mainly worked in the bay. This time, it was a headache because of three or four bolts only. They simply didnt want to leave thei homr and the one securing the tailshaft, another above the GB, and the one securing the lipstick was a shit. Mates mate, Davo caught fire 🤣, nearly opened his chest up with a grinder 🤦🏽‍♂️ and both mates nearly had a plate from the box land and slit their head open. Fun times. We all survived. Not the easiest working with limited access on jackstands. As I'm sure we can agree these are the memories which make us love our car. For all three of us, was an awesome weekend and Sunday 3.30am before tools down was a fantastic effort. I need to upload pics, but looks like it needs to be via Url now. We used to be able to just upload pics back in the day. It's been that long! 🤪 Im currently spraying rustoleum under body, not because it's rusted. It's super clean, but just so it's protected for the next 10 years. There was a few surface rust spots. Which pretty much wiped off with a 3M scourer.  Really impressed with how well the previous owner maintained it. Bank account went down so quick! Service, then GB - managed to get a spanking new 34 genuine box from Nissan. All the rest of the conversion parts from Kudos.  Went with a Nismo short shifter. New pedals and Exedy Clutch and FW. Ordered the Prp Rear Main Retainer kit which should arrive Friday and my first engine mod part just like I did with my S15 will be the Tomei Expreme Turbo Outlet. Already on order. It'll likely sleep next to me on a pillow during the coming months. 🥰 Last build was on my JET200GT profile and on SAU and Hardtuned I had documented the build. Planning to try to do that again. Brands feel scarce now. Wish we still had ARC and Apexi parts readily available. Exhaust - need some advice on this. I had an Apexi exhaust on the S15 and loved the tone. My mate had a HKS HP Silent on his 33 and suggested I go with that to avoid drone. I can't remember hearing an RB25DET running that so will likely need to wait for a meet or something to hear it.  Not after big power, just enjoy building it, and drivability with minimal negative attention.
    • Have a chat with Ben at Moore Performance or Jesse at JS Performance.
    • Thanks both. All good advice. Reminds me of drilling through stone wall for drainage pipe 😬 I'll let you know how I get on if I still have use of my hands afterwards 😅
    • Finally got shipping number for the intake and throttle body, shipped by UPS, so "should" be in my hands sometime next week, fingers fracking crossed
    • I'm so far behind in the jobs I have to do at both work and home (including car) that I have become immortal. There's simply no way that I can die now.
