this is my first post and unfortunately I have to start with a problem...
I drive a Smart ForFour Brabus.
We do a lot of modification at this car, at the engine and also there is an tuning file at the Ecu. We use the car for mountain race. At the moment it has 230 hp on Dynamo. But the Fueltrimm is no so good.
So I want to do some modification on the rom.
The Ecu is the same as in the colt czt. I can read and write the rom with Mitsu Bootloader. I bought a second ecu (used one) from a czt and write it with the rom from the smart Brabus, because I was afraid to write the stock ecu.
I have to write the new Vin in the Ecu but this was not the problem and the ecu from the colt is working without any problem in the smart.
But I have a problem with the checksum. If I open the stock rom I get the message that one or more checksum value are incorrect. But the checksum is ok.
If I correct the checksum with EcuFlash and after I write the rom, the Engine did not run.
I have the same problem if I open the stock rom from the colt Czt ecu.
Somebody who can help me with the checksum or had the same problem with the colt czt?
Thanks a lot!

I would be very happy if somebody could help me reading my ecu. Its from a 2005 EDM Czt.
It does not respond to any init code. I also tried Ecu unlocker without success.
