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.

xtalhps is the clock speed its in the cal file as its needed for the timer intervals for the timer table lookups and references

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)

Here are a few. I have a few more that I’ll post up in a bit.

And the rest. Let me know if you need close ups of anything.
