Hi, I spent a couple of evenings trying to dig into ECU modding, I have a chinese Galletto, ton of software, but what I miss is a good tutorial or guide through the process. I have a long experience with cellphone firmwares modding, so I know what a HEX editor is and what checksum is etc. But I still have gaps in knowledge about the ECUs. I have no desire to mod commercially, but I see it as a challenge to accomplish the modding myself.
I bought a Marea JTD110 with a faulty ECU (EDC15C7 CF3), which is not able to run fans (it does not ground the right pin). I bought a "new" ECU to replace the faulty one, but I would like to transfer immo and odo settings, if possible.
Both ECUs are HW version 0281010342, software version would probably be different.
Is it possible to download flashes from both ECUs and simply replace immo and odo data of course with keeping the checksum? If not could this ECU be virginized (immo reset)? If not as a last resort, how should I turn the immo off?
Could someone please tell me what exactly should I download in the Galleto SW (Flash / EEPROM - Complete / Tables, which addresses) for immo and odometer? On which addresses can one find immo and odo values?
Or am I viewing it completely wrong? :-) Thanx a lot
