Gen v tahoe with long tubes and catless y-pipe. O2 trend further rich as the drive goes on until the trims pull all fuel away and the truck dies. What gives?

Looks like you missed a few things for the "test" - write entire with this one. You'll also want to kill the long terms and adjust your O2's for their new locations. This should get you going in the right direction though. Just make sure to do a write entire as I'm not sure cal only will make the changes.

Thank you for your suggestions but how does this prevent the o2's from trending rich as in higher voltage over run time? The voltage averages higher and higher until it eventually flatlines(above switching voltage) towards the end of the datalog. This causes the trims to pull all fuel. Has no one seen this before?
