Different between old version and new version

I know this have been talked about so many time, but I can't really find a clear answer.

Are you asking about the PFC ECU or Datalogit Universal vs FD3S?

HOW TO IDENTIFY P-FC VERSIONS


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.

The first PFC's were:

1. 414-Z001 - 1995-1998
2. 414-Z002 - 1991-1995
3. 414-Z003 - 1998-2002


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:

4. 414-Z004 - 1991-1995
5. 414-Z005 - 1995-1998
6. 414-Z006 - 1998-2002


POWER FC NUMBER------------------------COMMANDER NUMBER

414-Z001 --------------------------------415-Z001
414-Z002 --------------------------------415-Z001
414-Z003 --------------------------------415-Z001
414-Z004 --------------------------------415-Z002
414-Z005 --------------------------------????????? (doesn't say)
414-Z006 --------------------------------415-X001

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

415-Z001--------------------------414-Z001/414-Z002/414-Z003
415-Z002--------------------------414-Z006/414-Z005/414-Z004
415-X001--------------------------414-Z006/414-Z005/414-Z004

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).

Over the years the base map has changed from stock to a mod version. Otherwise from above it seems to be only internal electronics. Like you can have transistor or chip radios and both can work exactly the same.
