I bought this on ebay and I am now thinking this is a 99 spec unit... Here's a picture...

 

What does it say on the box? That pin arangment looks different. Pull out your stock ecu and compare it.

R.K.

 

its not the right connection

 

The box says FD3S IV 13B REW....

 

That one isn't compatible with our cars. Someone makes an adapter though, I forget where I saw it though. Maybe someone else will chime in.

 

yeah we're series I through III iirc thats for the newer FDs

 

version IV is 95-98. I had the same problem (albeit from a yahoo auctions seller) - seller's fault - and eventually got my money back.

 

I got this one from an ebayer who email is from yahoo....


Being that it is a 95 thru 98 version...will it work on a 95 RX7?

 

no - only 12/95 onwards (16bit ecu - which was never used in an export car - not even the oz-spec, which was sold until 98).

 

yes but not a US model. I think the Roman Numeral marking was for UK car...I think.

One model number that I know will work for sure on 93-95 FD US model is

PFG FD3S 4 XXX-XXXX

 

no, the roman numeral is the standard for japanese versions

direct from apexi, these are the current numbers you should be looking for...

FD3S (????) 91/12?95/11 13B-REW 414AZ004 (set) 415-X001 (commander only) 415-A008 (boost control add-on)

FD3S (??) 95/12?98/12 13B-REW 414AZ005 415-X001 415-A008

FD3S (??) 99/1?00/9 13B-REW 414AZ006 415-X001 415-A008

anything else is a superceeded version, and is best avoided

 

sorry, the cut n' paste kanji isn't coming up

in the brackets should be

(I-III)
(IV)
(V)

we suspect that the V unit works with version VI cars - but I only have word of mouth to verify that. There is, however, a separate unit for 280ps cars.

 

thats the same unit i have on my car. its the 99~ model i'm sure.

 

nah, it's a 16bit connector - so it can be from anything from 95-02. If it's got IV on the box then it's not for a 99

 

afaik the 95 fd ecu connectors are completely different. refer to attached pic of 95 ecu. I was confused as to switch over from 92-94, 95, pin layout. A mate, also on this forum removed his 95 ecu for comparision sake and the connectors are completely different.

image00013 is 95 fd3s ecu
image1 is what i've got running on my car

 

Thanks for all the input...the kit is now for sale.

The number on the box is 414AZ005....

 

Try to sell it in the uk forum(mazdarotaryclub.com).

 

Anyone know if the guts of a 16bit PFC are any different from the 8bit unit? I know the stock ecu in 16bit was substantially better, I wonder if Apex changed anything in their box for the later cars?

 

fd3s7007: I had a IV unit and it was identical to the one you have pictured (16bit). The other is clearly an 8bit connector, and from a pre-december 95 FD (ie: a version III)
