Found two fuel maps, is this right - Euro MY03 WRX
Posted: Sun Jan 01, 2006 2:20 pm
I've been validating qoncept's reverse engineered hex addresses of my Euro MY03 WRX. In doing this I came across what appears to be two fuel maps. They are only slightly different. The above ROM image is stock (no 'external mods'). Does anyone know what this is all about (see illustrations below)? Are they both used? If so, under what conditions?
Illustration 1 (fuel map found by qoncept):
FUEL_RPM_START = 0x20C74;
FUEL_RPM_STOP = 0x20C93;
FUEL_LOAD_START = 0x20C95;
FUEL_LOAD_STOP = 0x20CB4;
FUEL_START = 0x20CB7;
FUEL_STOP = 0x20DB6;
Illustration 2 (other fuel? map):
FUEL_RPM_START = 0x20DB7;
FUEL_RPM_STOP = 0x20DD6;
FUEL_LOAD_START = 0x20DD8;
FUEL_LOAD_STOP = 0x20DF7;
FUEL_START = 0x20DFA;
FUEL_STOP = 0x20EF9;
Thanks in advance for any advice,
-Steve.
