True dual exhaust and O2 Sensors

Although there is a possibility that the module hardware may support
dual HEGO's, I would imagine that the second HEGO option will have
been turned off in the software to avoid spurious self-test error
codes. Unless you're an EEC-iv hacker, you may have a problem
re-enabling it .......
