was calling the function that you listed, and that led me to find the variant
pointers that start at 0x1090, which specify the map pointer's offset from
0x11E0.

I think this is already documented somewhere here. The R2 stored index to the
table is used in TabIdx (0x1090). That gives you the index to the address table
TabAdr at 0x11E0. The lsb of the second index indicates the format of the table.

The location of TabIdx and TabAdr is the same in all versions of the 944 ML3.1
code. But at some places the code changed significantly so the R2 stored index
is not the same for all versions.

I agree with the rev limit location, I used that with the 8K bin on a 944 turbo. The ML 1.2 stuff is mostly Herr Wilks domain. He has the time spent...

Thanks for the info, guys. Yeah, the ML3.1 seems to be a bit nicer to work with than the ML1.2, at least for finding the maps. Trying to figure out which one...

... That's easy. The following function is called before a table with variants is read. The read function for tables use R2 as index. According to the plugs...
