BLM cell boundaries 12P

Where are the breakpoints defined in the xdf for BLM cell? I can only find the delta map/RPM for the breakpoints table but not the actual breakpoints to determine which cell is in use for the fuel calc.
Thanks

Nobody? I'm in the only one still playing with GM OBD1 calibrations?
Guess it's time to move on.....

Why do you need to know what cell you are in

I know which cell it is using, I'm looking to change those cell boundaries.

The cell boundaries are hard coded in 12P. They were moved out of the cal segment and in to the code segment. This was done due to items containing direct memory address' that will change with every code release. Having it in the cal segment added another step to migrate cals to new versions for an item that 99.99% of people will never need to adjust.
If you have 12Pv112 then here are the items including the address...
Code: Select all
E07C 30 31433 BLMx: .byte 0x30 ; BLM Params - RPM 1
E07D 40 31434 .byte 0x40 ; BLM Params - RPM 2
E07E 60 31435 .byte 0x60 ; BLM Params - RPM 3
E07F 90 31436 .byte 0x90 ; BLM Params - RPM 4
E080 20 31438 BLMy: .byte 0x20 ; BLM Params - MAP 1
E081 40 31439 .byte 0x40 ; BLM Params - MAP 2
E082 60 31440 .byte 0x60 ; BLM Params - MAP 3
E083 80 31441 .byte 0x80 ; BLM Params - MAP 4
E084 A0 31442 .byte 0xA0 ; BLM Params - MAP 5
