 gas into the intake track and then increasing timing and leaning fuel would
 cause knock, but the idea of  0ing out 1b3 is to disable the EGR function so
 that not only does the EGR not function, the mixture shouldn't be leaned and
 the spark not advanced so what's the deal?

If the ECM never commands EGR then the flag is never set, the ECM doesnt go 
into EGR timing/fuel. Same as raising the EGR enable temp....from what I 
gather anyway :-)
