hi everyone

I have a ibiza cupra tdi pd130 ECU code 038906019LA. I have found the remap on my car to smoke a lot which tells me its a poor remap.
Now i have looked into changing this but can't find anywhere that does the code with the letters (LA) at the end of the digits 038906019?
So my question is can i use a file with the same digits but with the letters (NJ) at the end so instead of it been 038906019LA it would be 038906019NJ? any help would be much appreciated.

Thank you mike.

Is this identical engines? ;)

No thank you for that, the only info i had was the the code i gave didn't know the engine codes :)
