Wondering if anyone has figured out where the coolant temperature correction maps are for fuel and for ignition?

I have been through just about every ROM and Definition for all of the EVO models and I cannot believe that nobody has found these maps.

There are only a few people who can do disasembly of the ECU, and only a few of them can go very deeply into the code. Those poeple either don't think the maps worth finding or have other priority's or even the ECU itself does not have maps but use other variables to do the adjustments if there are any.

Found them. Results posted elsewhere

Found the ignition trim maps for engine temp and air temp today too.

Disassembly helps in finding the scale addresses afterwards as well as links to other maps, but it is systematic searching and testing that finds what all of the maps at all of the addresses do.

The only map that is proving to be elusive is the fuel map vs engine temp. I have ripped this rom apart and cant find it as yet. The ignition vs air temp map has a second map that controls the load at which it becomes active, so at idle and cruising you dont see changes to the trim map. That made it difficult to find. I am starting to think the fuel vs coolant map does something similar. If it's there I will find it.
