There is only the option to program out the VATS system in the ECM calpack. The VATS module is where the codes must match ... or rather the resistance of the keys resistor pellet. There are 15 "codes" that correspond to the following resistances (in Kohm).:
1 = 0.402
2 = 0.523
3 = 0.681
4 = 0.887
5 = 1.130
6 = 1.470
7 = 1.870
8 = 2.370
9 = 3.010
