Clock speeds of any/all boxes

Unread post by tvrfan »

Guys,
does anyone have a list of clock speeds for the various units/bins ? There are 9 speeds in the Ford manuals, but I reckon there are more.

I am trying to decide what to do with SAD for the timer setup. It's a really important part, as EVERYTHING has timers all over the place. So any information welcome, even if it's just "My XXXX has a x Mhz crystal in it" If you have any pictures of boards with the crystal on them, will be useful.

jsa has suggested that later bins like RZASA may have a 27Mhz crystal, which would be normal progression from the 20Mhz maximum in the manuals.

Thanks.

Some box codes and the crystal for your list.
DE SFI-SD1 EEC-iv has crystal with this on it # E4VF-AA NDK8723 (couldn't see a value).
0DBE EFI-SD153 EEC-iv has crystal with this on it # E4VF-AA NDK9023 (couldn't see a value) .
8PV EFI-SD20B EEC-iv 12.0 mhz.

1DCE + 1DCD + 3DDB + 3DBC ETV-456 EEC-iv 15.00 mhz (these boxes also have ETV-156 on the board).

4DBG ETV-557 EEC-v 18.0 mhz.
5TAA + 6TAA + 6TAC ETV-512 EEC-v 18.0 mhz.
5DBC + 6DBB ETV-513 EEC-v 18.0 mhz.
6DFD + 6DHD STV-516 EEC-v 18.0 mhz.


(falcon au OBD flash memory)
WANA ETV-714 EEC-v 12.000 mhz.
WABF ETV-712 EEC-v 12.000 mhz.
12BE + 12VC ETV-734 EEC-v 12.000 mhz.

Hope these help.

I have several PCMs sitting in my garage at home. Random as they may be I will open them up this weekend and try and get pictures for you.

Thanks again - trying to get more data so that SAD can recognise the timer structure in more bins.
The calculation, ' IO_Timer to millisecs' is the first foundation to build on.
So far, looks like early bins do 1/1000 (true millisecs) and later bins do 1/1024 to make maths easier/quicker to get to other fractions of secs.

(released 5.0.3, see other thread)
