I\'ve finally managed to get my hands on a ap engineering power fc, comander and harness but is there anything else I need? I want to get rid of the afm and any other additional parts that can be replaced for the power fc, is this possible and what would be involved? Regards ben

by afm do you mean the air flow meter? If so I don\'t think you can, the PFC takes its readings from the standard sensors (air temp, water temp, etc) as the stock ECU does AFAIK.
graeme
i think you can to be honest , other wise how would all the single turbo cars work with the cone filter slotted straight onto the turbo ??
OHHHHHHHHHHHHHHHH and thats my 10,000th Post :D :D :D
Nice one Stu :cheers
Back on topic...
With the Apexi you can eliminate the AFM completely - but you need to get a MAP sensor from an FD or alternatively a GM 3 BAR sensor, as the Power FC uses this and throttle to determine fuelling requirements. I believe you also need to use the FD IAT sensor (inlet air temp sensor), this is normally located under the upper inlet manifold on the FD, but you should be able to replace the one on the FC\'s throttle body inlet with the FD one - not sure if the threads are the same ?
Pete Taylor and Liam are/have fitted the Power FC to their FC\'s - so they are the guys to speak to.
prof is correct, need either fd map sensor or gm3 bar AND also fd ait.
cant remember if the fd ait was straight plug in or not.
you need to cut a wire on the harness (speed sensor i think it was)
best place to look for help is

look in tech support.
theres no need to do the 3rd coil mod as its the ap eng model :)
thank you to grinder, prof and liam for your great info, that pretty much answered my questions :) im planning on running an fd uim when i know a little bit more about it, ive got a polished uim but its gone bareback on me, literally has nothing on it, just nice and shiny:) what else is connected to the uim? or even better has anybody got a schematic diagram for fc3s and fd3s? ive been looking on ebay for 3 bar map sensors and i came across an apexi d jetro kit, can i use this on my pfc ap eng model?
i posted this up in the tuning yourself stickie :)
http://http://www.innovatemotorsports.com/resources/FCedit_tutorial.pdf
stumbled across it whilst searching the big wide web :)
i had a quick ebay search for the kit. $300 usd for it!
the banzai kit (inc harness) only costs £320 landed uk.
gm3 bar mapsensor i found for about £60-£70
fd ait, i have anoother back home as i had to buy the banzai kit in the end just for the harness as i already had the gm3 bar and fd ait so i have one spare. paid £6 & postage so same for you if you need it (used)
fd uim to fc:

most important is to port match it.
the fc uim can handle upto 500bhp, the fd one just looks nicer :p
You can get rid of everything on the UIM apart from the temp sensor and the TPS, use the FD throttle cable and just do some of the things I did in my thread. believe it or not but the FC will run on a FC boost sensor but I have gone for the FD map sensor. There are no wires to cut with the AP Engineering one, its a direct plug and play once you have those FD sensors. You should have the commander or datalogit to successfully adust for the map sensor. You can not just chuck a 3bar one in and think that it will run because it wont. You do not have to lower the power steering pump, i did that because I dont need the Greddy inlet tube due to the location and configuration of my FMIC, it just suits my application.
When fitting the FD UIM you must port match it as Liam has stated and in my case I produced an adapter which seems to work very well and is a known mod especially in the USA.I did very little shaping of the LIM and UIM, if anything just cleaned up the rough metal, the porting was all done in the adapter.
ideal, in that case liam i\'ll take that one off your hands, how would you like payment?
thanks for that pete, i had a quick read through your thread and there\'s some great info in there, i\'ll have a good old read nearer the time :). my plan was to ditch the power steering pump as im going to fit the gilmer pulley kit for peace of mind :) and just run an electric ps pump. i didn\'t expect the 3bar map sensor to be a simple switch over, that would be amazing :) so when your in the datalogit do you just select the method of sensing the air intake?
I think i will go down the adaptor plate route, just need to find someone local that can make one for me or the other option is to just buy one http://http://www.rhdjapan.com/feed-surge-tank-swap-kit-fc3s-13b-53693
pricey though :( and it doesn\'t state what exactly comes with the kit or if the plate is port matched, there\'s some kind of plug or sensor with it?
paypal as before is fine. not sure how much postage is but call it £7 total.
what elec ps pump have you found?
m1tch on here said a elec pump off a saxo fits.
That\'s exactly what I\'ve got but I\'m trying to find one off a more reliable car as these tend to fail, can you pm you paypal details please
read this, its perhaps the best explanation of the PFC and datalogit I have seen so far and its all in one thread. Its for the celica but does explain the whole tuning thing extremely well and about 95% is the same as for the RX7\'s.

You will have to ignore the bit on airflow as thats vehicle specific and not the same for rotary PFC\'s.
Plonk this other address in as this chap knows his stuff, its from the rx7club.com but its got some really useful stuff.

You can make the adapter out of 15mm alloy, you just have to make sure its perfectly flat, mine was made by my back door with a drill,dremmel and some good filing.
