ELM327 is not currently supported. Only ELS27

this was a Diesel convers 14xx a converted to Petrol so has moded code. the mph to kmph as you know 097 00p 01 km i think i have found the flagg byte
for the 6k Diesel 8k petrol ill confirm later.

Glad my program brings help!
I think, we need to create online spreadsheet with descriptions of offsets. I started here https://docs.google.com/spreadsheets/d/ ... Gq-dkXssh0

Also, the mileage is stored in the next lines:
0770: xx xx xx xx 32 D1 xx xx 32 D1 xx xx 32 D1 xx xx
0780: 32 D1 xx xx 32 D1 xx xx xx xx xx xx xx xx xx xx
where the next bytes:
32 D1 - is a mileage in km, calculated with using XOR-table

I try to use it, but your tool claims about a wrong identifier when trying to access my TRE27 from Tunnelratselectronics.
Just curious, what protocol do you use?

Goof info of the mileage. Yes, i read somewjere else that vendors place the value multiple time inside the eeprom or flash.
So, did you find it by readout after driven a mile?
And what about the XOR „encryption“? Do you know how the value is calculated and where this XOR Lookuptable is in the eeprom?

What km does the odo show with the value given as example?

And, is it possible to read the on chip bootloader code? I would need this to restore a bricked/locked odo.

AT I
ELM327 v1.3a

ST I
STN1170 v3.3.1

Code: Select all

AT I
ELM327 v1.3a

ST I
STN1170 v3.3.1

The adapter connects with 9600 Baud 8N1 by default.

So it would be enough to add "Set IPC to 1km" ...

It's free and works perfectly!
Thanks ...
It may not be a problem to update older dashboards with red LCDs.
Can I also support the J2534 protocol for UCDS cables?
When reading main and extended flash, you can do a Convers + clone with additional features.

You cable - ELS27 (STN chip). Native ELM327 will be supported soon

I use this one https://images.app.goo.gl/oyBCfCHAvhsnMMeT6
Maybe it's a special firmware on it to support ELMconfig.
What does AT I say on ELS27?
Maybe ignoring the string it sufficient.
Also ordered an ELS27 on ebay für 20 bucks.
