IAM is ignition advance multiplier, you will need an ecu logging device to see it or techstream software.
700J is an old calibration, latest one for that model would be ZA1JA01J
that old calid will not have the DI seal fix or the lastest idle dip fixs. you dealer should update it for you.
if you have a flashing device the updated rom is at end to tactrix ecuflash post link below
