Ok almost 1 year update.
IT DOESNT WORK!
About a month ago I got a CEL, secondary o2 reading rich, 02 circuit problems.
After discussing it / trying stuff with my tech, the problem is not the wiring or a bad o2 sensor. It looks like the secondary sensor is reading rich, and the signal is not clear back to the computer. This is making it think there is a circuit problem and making it think the primary sensor is bad as well. The sensors are good, and there is no short or bad connection we can find. Clearing the codes works, but the CEL returns after the car is turned off and back on again.
Everything seems to point to the computer simply taking this long(almost a full year) to figure out what it was seeing and decide to throw a code.
So since once again as no tuner will say their tune maintains o2 sensor readiness, Im putting my stock x-pipe back on so I can pass emissions next month.
Its been fun, Im gonna go bang my head against the wall now.
