Default p0430

So here I go. I went ahead and replaced the right side catalytic convertor. I even replaced the 5 wire sensor, and the down stream 4 wire sensor. I did all that and the problem is still here. It won't go away. I get the p0430 cat efficiency code. I still think it is the ecm and a fuel map problem. The numbers show that the right side of the motor is getting twice as much fuel as the left side. Why is that? I get a reading of .31 on the left side, and a .60 on the right side. Both those are the up stream 5 wire sensors. No reset has ever fixed it. Is the fuel pulse width on the right side adjustable? Can you direct me towards the right place to address this? . . . Josh
