opel antara DCM3.7.ap clone help, d flash goes strange after writing, see this

**sdnatlst** · 12th October, 2020, 05:28 PM

hi all, i am reading and writing with ioterminal, flash and d flash read OK on orignial ECU

when i write d FLASH and FLASH to replacement ECU, flash looks fine and compares perfect but D flash has weird writing in, like computer test and 1st wakeup, see dflash files original read and after ive written it

my software doesnt see the VIN in the ecu after its cloned, has anyone got experience or knows what to do, will car still start? i dont have car with me

thanks!

This is rather interesting topic.

Are you trying to write on exact same hardware ecu?

Looks like your entire eprom gets overwritten with some data, and there are strings like "COMP TEST" and "1ST WAKEUP".. I wonder what happened when you try start the car (antara by vin number)?

VIN number also not in new eprom so it probably wont work..

Interesting string in original eprom "NOT VIRGIN"

looks loke new eprom lost it

It has been some time since you posted, any development or conclusions on this topic, can you tell us how it went and what you learned?

Hello. I did the same.
What became the solution?

Dcm3.7ap...
With ioterminal is not so easy...
Software can't detect the right MCU...

Ioterminal will read also write d/p flash if you choose the wrong MCU...

Open ECU and check and compare...
If the selected mcu is the right one...
Same with donor ECU...
If MCU is not the same...
Ioterminal will write, but cloning will not be successful...
