e38/t43 commanded idle issue

got a car that has a commanded idle issue. its a 70 implala swap with a current performance harness

in park the commanded idle follows the in p/n idle table when you shift it into gear it goes to 896 rpm commanded no matter what you set idle speed in gear at,

car came from another person whe chopped all the tables up chasing the issue and the first thing i noticed was the commanded idle rpm problem

any thoughs

Someone has "tuned" it using HPT. Would recommend beginning with a stock tune, and making your own adjustments.

Below is a JPEG of the Idle table that is causing the issue ...

Is there a cax for that table? Or can you just set it all to 750. This car was tuned somewhere else and I really don't want to be married to this car. Just trying to help out a freind.
