on hondata's page there is a note that differential control will be lost (upon install) anyone know if they are referring to ATTS? I thought the ATTS unit was seperate from the ECU....anyone know more about this?

 

The ATTS unit itself wont be lost, but it wont function. The ATTS unit has a control unit of its own, which interacts with the ECU. And since the hondata doesn't have the data channels to communicate with the ATTS control unit, your ATTS unit wont function.
