Title: Opel Omega B - Simtec 56.5 - Elm327 Help with HEX / Mode / PID
Post by: opel_calibra_16v on November 27, 2023, 09:46:32 AM
OBD Plug: ELM327
Engine Controller: Simtec 56.5 (90 491 975 / S96001)
Platform: Arduino (C, C++)

I have established a connection to an ELM327 with an ESP8266. can therefore read the data from the engine control unit.
I've already calculated a few things using a PID file and can already see a few things.
Now the only question is, there is more to the data (hex output).
Unfortunately I don't know what calculations I have to do to get the rest.

I got this hex value with mode 2101 on the header 8211F1.
Code:
80F1112B610106034028056062000079FFFF4600000000FF00B946818EE6E27C4B008000000144041800060000810008

what I already have: (attached screen)
(http://nefariousmotorsports.com/forum/index.php?action=dlattach;topic=22403.0;attach=39167;image)

Which data sets are still hidden in the hex and how do I calculate it?

--------------------------------------------------------------------------------------------------

I also have another question about DTC (error codes) and how exactly I have to read them and calculate them.
I've already found several data requests, but unfortunately I don't know how to calculate the hex data sets.
Does anyone have anything they can help me with?

Code:
pid: 1800FFFF
hex: 80F111037F18223E

pid: 18FF00
hex: 80F111037F18122E

........

many thanks for the help :)

Does no one here really know any information?
well, I don't really find that much myself, just pid files and otherwise really difficult.
I've been searching like crazy for about 5 days and only found sporadic information.
