- Periodically(about 30secs) LCD reinitalize should be a choosable option.
-At the IAC settings, theese are the options:
1. follow iac the tps while not in idle
2. leave iac at the reference position while not in idle
And there should be another option that could be used with the above settings: "set iac to zero when MAP>90kpa", because there are some cars where the iac valve is not connected into the intake manifold, so it should be closed at boost conditions.
