I'm going to japan in August and was wondering if the Japanese Power FC's work here in the US versions? Because I was thinking I could pick up a used one out there. Would I have to buy a US commander?

 

they work fine. just a couple of wires to cut. egr stuff and the jap commander will work too. I have one.

 

which wires?

 

the 8 bit PFC work... Make sure its an 8Bit... if its not then it will not work...

 

Dude aren't all pfc's 16bit??

 

No.....

Power FC's are different depending on what year your FD was built. I.E What series

91 DEC - 95 DEC FD3S RX7 13B 1-3
95 DEC - 98 DEC FD3S RX7 13B 4
99 JAN - 00 SEP FD3S RX7 13B 5

 

Wrong. ALL PFCs are 16-bit.....that is one of the advantages of going with the PFC.

You are correct that you do need to get the right PFC for the 93-95 model years.

 

Yep, ALL PFCs are 16 bit. Where did this 8 bit bullshit come from?

 

from the Power FC forum, I assume the pic below is correct

 

i stand corrected... i dont know where i got that from O.o.....

i think from the notion that later model FD's had different ECU's....

then with the fact that you need the correct series PFC... :shrug: hrmmmmmm


Ah well. my mistake.

calm down.

 

the need for correct ECU's stems primarily from the different harness on the later 2 versions. The IVs no doubt run a slightly different map - the 280ps V and VI definitely do.

 

just so others know the 280ps harness does not exactly match up with V and VI version. The fd harness connectors (3in total) but the PFC has 4 slots. Last unoccupied slot is EGR.

 

The 93-95 (and 95-98?) stock ecus are 8-bit. Mazda upgraded them to 16-bit in 96 (or 99?). This is probably where the confusion came in.

 

They are frequently on Ebay for about $700-800 with commander from Japan, brand new. Dunno if you'd save a lot buying one in Japan, unless it was used. I'd rather get a new one.

Regardless, the Japanese PFC's are identical to the US versions and will work great.

Yeah I was thinking of shelling out the $800, but since I'm there, might as well see if I can get one for cheaper out there

 

Unless you go out of your way to find one of the bigger discounters (which is going to take time and money anyway), you'll find that the RRP for the pfc in japan is still a little over US$800 (we tend to get ours from internet auction as well!).

 

lol ok...hmmm how about used rims...?

 

used rims you can get from shops such as upgarage, autobacs secohan, off garage (there's plenty about). trouble is getting them back - you'd be paying well in excess of US$100 per rim to freight them home (no idea what excess baggage rates would be - but no doubt not friendly - and it won't be fun lugging the rims about).

 

is this correct? someone?

 

Cool ok DaiOni thanks for the info...actually thanks everyone for the info on the power fc. I'm spiking 14lbs occasionally when i step on it so I need something to help back up that little spike so I don't blow my precious motor

 

Ok well I'm now in Japan, around the Roppongi area. If anybody can tell me where I should go to possibly pick up some used rims? Lol

 

i thought that stock ecu was 8 bit

 

ok so is this pic correct? Cuz I got a power fc for pretty cheap from Up-Garage. Or is it different w/ the different series of power fc's

 

I go the japanese one from ebay for 799, and YES that picture is correct because those are the wires that I cut.

When I cut the wires, I used small heat shrink tubing to insulate the wire ends.

 

Actually, to avoid any confusion, check this site out. (Same diagram but with wire colors labeled)
