I bought an Apexi ecu for my 1993 JDM FD3S with serial number FD3S4 020-1507 but without a commander. Now i found a commander for sale which was on a GTR33 with serial number FCC3 020 - 27462. Do you think that this commander is compatible with my Apexi ecu?
FD3S - 96-98 RX-7 old version
FD3S2 - 92-95 RX-7 old version
FD3S3 - 99+ RX-7 old version
FD3S4 - 92-95 RX-7 new version
FD3S5 - 96-98 RX-7 new version
FD3S6 - 99+ RX-7 new version
The serial number is important as this determines Commander compatibility.
Later Apexi upgraded the software version and made the chip in the ECU soldered/non-removable, unlike those above where the chip was a pin type and could be removed.
Apexi re-released the changed PFc's with different serial and part numbers:
The above numbers are from the Apexi website, but.... from discussions with tuners and owner it is quite clear that some commanders will fit some other Power FC's and that the list above is not a definitive 'this will ONLY work with this'.
COMMANDER--------------WHAT POWER FC ECU IT WILL ACTUALLY FIT
The 415-X001 is supposed to be a universal model that can be used with all newer P-FCs for most other cars Toyotas, Nissans, Mazda Etc. If you order a 415-X001 for an RX-7 it will come with the manual for an RX-7. So a 415-X001 for a MR2 should work with your newer model P-FC for an FD, but you wont get the car specific manual.
You will know if the commander and Power Fc ECU are NOT compatible as when you plug the together and switch the car on, the commander screen will light up, display the APEXI logo, and that will be it the logo will stay there and the menu will not be displayed (as usually would).

Sorry for reviving this old thread, I searched a lot but didn't find a reliable answer for my questions.

Why ? To me, according to apexi's site, the FCC3 020 commander should work on a FD3S4 020 ECU.
Also, I really appreciate the informations provided by cewrx7r1, but I have no idea where to find the commander's number... ( 415-Z001 or 415-X001 )
The only reference I can find is the FCC3 - 020 on thr sticker on the commander's back. and on the electronic board itself, I can only see FCC3.
At this point it's REALLY hard to find the PFC-specific commanders, the universal Commanders are much more plentiful and have been in production for like 15 years.
I'm 99% sure that FCC3 commander will work. If it's an EL screen commander, they were only made universal.
