How many times an ECM, in may case is an A4E4 from a C18 which stopped working to me after I have been writing a new firmware, which was sussesfull. After the tramsimmiin from PC to the ECM the unit was not able to respond at all.
Tere is write limits or counter on the ECM which limit how many times?
Thanks a lot

If you reflash from one application to another wyou cange the interlock codes.
if you connect ET you will see a software missmatch.
your going to need factory passwords

You are correct, mismatch warning is displayed and factory password is required. Then FLS, FTS and injector trims are required. I have done all of the above without any issues (including the parametes which are missing from the new application file), however, I am concern about the process, as I already managet to have an ECU iresponsive and a replacement was required.

Thanks dave10010 for the promt conclusion, you may be right maybe not, however jumping straight to the conclusion, without knowing the details and the essence of this project it is very dificult to understand the software and hardware access level.
Thanks anyway for your straight answer, I really apreciate it!
