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

Thanks for the imput guys, will look into this pressure converter, thanks!

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)

    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
    • BTW I measured the jack I have, it is 70mm at the saddle but you only have about 700 until it returns to 150mm high at the cylinder so it is good but no magic bullet.
