On board datalogging trigger conditions The Hondata s300 uses different connecting pins in the ECU from the s100/s200, and also has a slot cut in the side for the USB connector, so the ECU must be modified for use with the Hondata s300.

This Hondata s300 is made to fit in a full frame OBD1 ECU case (US and most markets) not JDM
