Hello,
I tried to find adresses for some maps for my 53040007 in order to improve cold weather startup and performed some pseudo-scientific match&search maps from other ROM definitions with XVi32.
They should be right, but I think a confirmation from someone understanding the ECU code is necessary (especially IPW adder map that didn't match):
