How are you reading/writing the eeprom to the ecu? Have you read back the eeprom from ecu(2) to verify it has changed.

In general there is no reason why you cannot rename or move the bin file, you just need to specify the path when you write it back

im using argdub's tool in boot mode 19200baud as it doesn't seem to respond in obd(for read). im going to give it another shot here shortly, when checking the write i only checked the changed immo settings that i had messed around with, im going to compare the key this time.

in one of onsperformance's replies he said that he was having a eeprom communication error and changing the file name back from immo.bin to 95040.bin let it run.
i'd like to lable the file itself, right now i just have them in separate folders.

I don't think I'm using the current argdub tool, but I had no issues reading a bin and writing it to tmp.bin and 032mj.bin yesterday. Make sure you don't switch focus away from the terminal where you are doing the read/write, that was consistently breaking it for me.

Usually I'm the person who figure it out himself. However...

Long story short. Bought cheap Chinese KKL 409.1 cable with CH340 inside. Didnt work.

Swapped CH340 chip with FT232RL chip (connected FT232 modules TX and RX to a CH340's TX and RX pads, chip is removed of course), more progress yet still not working.

With CH340 couldnt get cable echo, now with FT232 cannot get response from ECU (0x07). Doesnt matter bootmode or OBD.

Have 3 years of electronics engineering background so I know how to solder and stuff.

Power for ecu comes from 14V 3A PSU.
All the wires are connected correctly.

I think I had 07 the other day, power up the ecu before plugging in the cable to the odb port fixed it I think.

Hello,

I have managed to get everything communicating with each other, but the pic of which pin to ground doesn't match the circuit board inside my ECM.

I've attached a pic of the label on my ECM. Any assistance on how to get this one into boot mode would be great!

Thanks!

Just take out the 24C02 serial eeprom to Immo OFF content.

The picture you attached is not showing.

I have followed the instructions at the beginning of this forum, and can get my cable and software to communicate with the ECU. However, I cannot get it into boot mode to allow me to Read/Write the EEPROM.

How do I do this on my version of the ECU? The circuit board is different than the one posted in the beginning of the forum.

Thanks again!!!
