Thread: ECU NUMBER

Can any tell me if this number is for a flashable ECU.

1880 MSB101340.

Its the new/up graded one I have just had put in and was purchased thru Davis.

Thanks,

ECU VARIATIONS
Although looking and functioning identically there are in fact two distinctively different ECU types which have some different diagnostic capabilities. The first and therefore earlier type is referred to as the non flash programmable type. This was replaced in late 2002 with a flash programmable type. Non flash types have part numbers that start with MSB while Flash types start with NNN


Non flash programmable type ECUs typically have just one vehicle types maps pre-programmed into them by the factory. This means they only have one Vehicle variant / fuel tune code and cannot be set to any other. Sometimes however, they might have more than one code stored inside an ECU or the ability to switch between multiple options for a given type. We believe that up to 6 could be pre installed at the same time. If an ECU does have more than one code pre programmed into it can be told which code to use by changing the code to the one for the configuration that you want. Of course, you need to know what any other codes are that may be installed and then try them in the ECU to see if it changes, meaning it has that map installed. Sometimes the sticker affixed to the edge of the ECU itself, which bears the part number, also shows which vehicle types the ECU can be configured to. But if not, fortunately the code can only be one of a handful and can even be deduced to some degree using the information supplied here as a guide.
Flash programmable type ECUs have the added ability to have their Vehicle Variation and fuel tune maps re programmed diagnostically, which is availaible as a seperate capability in SM201. They also have an incremental programming history memory which includes information such as the VIN number, date of programming and an assembly number which identifies what an ECU was programmed with.
Although part number information has been provided to help identify which type an ECU is, the easiest way to tell is simply to connect to the ECU and read the programming history. Non flash type ECU's will not support the function and flash types will show you the history including the VIN number.
