30-1101 (Series 1) vs 30-6101 (Series 2)  Supra / SC300 / GS300 EMS pin differences: 
The EMS functions assigned to certain pins have been changed and no longer match the 30-
1101 EMS. Unless otherwise noted, the following pins and functions will need to be manually 
reconfigured after using AEMTuner to convert a V1.19 (30-1101, Series 1 EMS) calibration for 
use with the 30-6101 Series 2 hardware.
