Need virgin eeprom Alfa 156 1.9JTD

[sinkews]

Hi. I need virgin eeprom file for Alfa 156 2004 1.9 JTD 8V 85KW.

I retrofitted cruise control but MES says that cruise control settings are not found in eeprom.
So I got another ECU (EDC15C7) from identical car which has cruise control and would like to swap ECUs.

This is the file from the one with cruise control, 5P08C3/ST95P08 eeprom.
Dumped using eeprom reader.

Thank you very much, works great.

Also if anyone needs to read and write those pesky 5P08C3s on the cheap I made an Arduino sketch (https://github.com/snsdosen/NinetyFive).

You can r/w easy in bootmode with KKL USB + ME7 Eeprom by Argdub.

Thank you very much but afaik that's for a different ECU (ME7 with 95040 EEPROM) and I needed Fiat EDC15C7 with 5P08C3.

I found that to read it on the bench I need to use Ioterminal Bosch ECU tool with FTDI KKL cable (Ch340 is not supported).
And to enter boot mode on that ECU i either need to generate 3 different signals of various frequencies (via Arduino none the less) or remove EEPROM from the board which kinda defeats the purpose.

Also 5P08C3 uses single byte address mode and 95040 uses double byte address mode so even if the CPU in ECU was the same uploaded assembly would read/write it in double byte address mode and garble data.

There are more options of hardware and software with varying degrees of cost to do this but writing this sketch was the fastest and cheapest way for me and hey, it works :p

No man, I use ME7 program with EDC15C7 5p08 even works with other Infineum like EDC15C2, you don't need I/O signals cheat.

That's good to know as I will program these ECUs in the future. I have a USB KKL cable with CH340 which I use for VW and ELM327 for MES.

How do you enter boot mode on this ECU?
I've read docs from ioterminal explaing the freqv method.

For bootmode I put boot flash pin to GND straight (I don't use 5k ohm resistance), put +12v for bat/key at the same time, wait 1-2 seconds and disconnect GND.
