Can anyone who has looked a a bunch of P4 bins tell me if there are any
bytes besides prom id, mask, checksum and the vector table that occur at
the same place on all/most bins?
Are the NVram locations the same on any bins?
i.e.
730azty ram locations.
L0000 ; Main Counter, 160Hz
L0001 ; status word
L0002 ; MALFFLG1
; b7 Malf Code 12 no reference pulse (engine not running)
; b6 Malf Code 13 oxygen sensor
; b5 Malf Code 14 coolant sensor high temperature
; b4 Malf Code 15 coolant sensor low temperature
; b3 Malf Code 21 throttle position sensor hi
; b2 Malf Code 22 throttle position sensor low
; b1 Malf Code 23 low manifold air temp
