Handheld wony display anytihng?
 

i just got an handheld for my power FC and pluged it in and turned the car on but i cant seem to get it to display anything. It just says Apexi?

Check the serial number on it; does it correspond to your unit? You might have the wrong model controller for your PFC. The guy I bought my car from had the wrong one for the unit.

Model compatability has been posted her before and last week.
DOH!

sorry but ive looked an havnt found anytihng, i have FD3S4 and the handheld is FCCZF0002-0090, i think thats the skyline one but not sure any one know?
thanks scott

Once again!

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).

there's also a lose wire issue with the commanders.. that has similar symptoms..

it's an easy fix.. it's in FAQ

thanks alot i got it figured out

it wasn't plugged in wasn't it? haha jk ;-)

So what was the problem? I'm having the same issue.

take the 2 screws out of the controller, pull the 2 halves apart and check to see if the brown wire came loose. thats what the problem with mine was. soldered it back and was fixed.

Thanks. That's exactly what happened to mine too! I never would have found that. So thanks again. Problem solved.

So it was the wire in the ecu that the faq talks about because if I plug in a commander nothing will show up, but if i put some pressure on the connector it will come up with the logo but hang. So I sold the commander since it was useless to me.
