the TI S103238 is a custom Ti processor , special ordered by Siemens.
S102976 ignition driver chips.
some serious potting removal there, hard work.
many of these ECU's use non standard chips.... or ASIC. and other custom ordered chips. to meet the makers needs.
i see a real intel flash 28F512 chip there ,
That 976 is a ST German chip.. alot of that alibaba stuff is clone junk, (some work but not for long or not at all, you need to buy St.com real part if bad)
my guess, is you traced the 2 ign. coil wires. to the 976s? is that your questions. related just to the drivers.?
S102976 listed as and ignition driver chip.
that S10 number seems to be a private Siemens contract number.
the clue to that, is two fold, non STI numbers there, non commercial standard, numbering used. Non JEDEC numbers . Non Mil spec, numbers..
and clue 2 , no Google hits. and that be hard to do if the number was commercial grade, and standard. (impossible and very big clue that)
here is the real company, that made those chips (st.com )

you can be sure they dont make them now. they moved on to thermal protected devices now. BU xxxxx parts
in many cases we contacted the makers, and asked what part this is , and was told its secret between, Siemens and STI. brick wall.
this is why many major ECU rebuilder hoard ECU's and then take one, ECU and use it as a parts source. (cannibalized)
id contact STI and ask them for the data sheet, maybe you can get lucky.
i bet the S code is a contract code. for Siemens. just my bet.
the chips might be just stress tested to last located near an engine. "HOT stress or burn-in tested" , just like MIL parts are done, and with special numbers there too.
good luck finding them....
id call them STI, would.
that potting is to keep parts cool near the engine, removed, they overheat.
it's not to hide a secret, as some things are...
