It is 14 cells table. The coolant value for table lookup is capped at $d0, so the upper 3 cells are missing, to fill the table upto 17 bytes extend the last value.
That sounds workable - up to 116C. The higher temp cells aren't that important for ect sensing and the last 4 cells seem to be the same in all the $EE calibrations I've looked at anyway.
Wherever, whatever the table is, it's just good to know it exists for these eeprom cars. Worst case it could be extrapolated through testing. Am I correct to assume these eeproms have to be dumped with a programmer, out of the ecu?

You might look at the bin to verify this shorter table because I suspect what you're seeing is the disassembler identifying a bunch of duplicate fill, i.e.
Code:
EFCB db $00, $00, $00, $00, $00, $00, $FF, $FF, $FF, $FF
EFD5 fill $FF, 27
EFF0 db $FD, $FB, $F9, $F7, $F5, $F3, $F1, $EF, $ED, $EC
I got hung up on this for a while when building these tables - didn't make sense to use them as a lookup table when they were different sizes. When I looked at the bin in a hex editor it became obvious the first 31 bytes of the high-temp table are all $FF.
