Not 8A94 but 8A95 and ends @8C3Eh, this file contains 213 maps...

You sure?

It's little endian, the two bytes starting at 8A92 is 92 8A signifying the map addresses start after this.

The next two are 3E 8C, there's a map at 8C3E, the next two are 4C 8C, there's a map at 8C4C etc.

It is not 16bit ECU! Just check if there is a map at address you found and compare it with what you get @8A95h Cheesy

Do you know how maps are laid in Motronic ECUs? If you do not you have to read to find out. Than you at least know what are the axes. Using experience (or knowledge found on the net) you can tell what the map is by the axes and data in the map... That is all... For example injector opening time map should be 2D map with battery voltage axis (I would look for wide range of voltage - for example 8 to 16V).

He knows literally nothing that hasn't been explained here.

And that is why it might be easier for him to check injectors, fuel pressure regulator and MAF part numbers in ETKA...

Most modern ECUs have 5000+ maps.
