Hi,

New to this forum and ecus and trying to learn as fast as I can.  Got a problem at the moment with reading my ECU through nefmoto software.  I can connect to the ECU but am getting decoding not licensed on the DTCs which I think is causing my problem.  I have used argdubs software to disable the immo I think correctly by modifying the 95040 0x12 & 0x22 and correcting the checksum by reducing it by 1 on each line.  Is there anything else I need to do to enable the ecu to be read on the bench without the clocks attached or furthermore do the clocks need to be somehow deleted from the immo bin?  I've done an awful lot of searching and reading and seemed to have got to a point where i'm in need of a shove in the right direction as i'm going round in circles!

Thanks for any help in advance.

Cheers
Bob

Which ECU?

Also copy paste the output of the nefmoto flasher.

Note that nefmoto's bootmode support is incomplete.

Also attached are the 95040.bin original and one I created for the immo delete.

I maybe getting my wires a little crossed here so apologies if i'm saying nonsense, but do I need bootmode just to read the flash, I just want to benchread the ECU to have a play about with it before I go and screw one up on a car!  It's quite a steep learning curve to get started!

No, you're on the right track.

You don't need bootmode for reading/writing the flash or reading the eeprom.

You only need bootmode for writing the eeprom.

You can try a lower baudrate...

Tried at all available baud rates at the result is exactly the same output.

Learnt something else along the way through reading with log files so i've attached the full log here if it makes any difference.
