afm offsets?

r31_gav · Post by **r31_gav** » Mon Mar 10, 2008 4:58 pm

in the address files theres an offset number.

do you need to change that number when changing afm? and then what number do you change it too? to the number in the address file of the car that afm came off or is there a relevant table to look up?

thanks in advance

Its the AFM measurement offset in millivolts (1500 = 1.5 volts)

Change it to 0 if using a Z32 or similar AFM after doing hardware modification to the ECU to take the AFM of different voltage

Is this relevant to the CA18DET when changing to a Z32 afm?

No... only for Z31/R31 which require a hardware modification to drop down the voltage (and represent the voltage change in NIStune also)
