Disable Rear 02 Sensors & Change Gear Ratios

[68 Z06]

I am new to this and am trying to get my check engine light to stop coming on with rear 02 codes. My Truck is a 2001 Silverado 5.3L Auto trans. I installed headers & air intake system and removed all cats. Truck runs great but keeps setting rear 02 codes. Rear 02 are still plugged in and tied up on frame. I also installed 5:13 gears and now get the abs & brake lights coming on at times. I cannot seem to find where I would make these changes in my tune to fix these two items. Any help would be awesome.

Post your tune

is this the kind of answers you get on this site? I was hoping this site would give step by step instructions for lay people that are trying to learn the system, not answers that assume you know whats going on.

If you post a copy of the tune someone can look at it and tell you what has to be changed. That's the way it works here.

well most likely the person did not know how to do that or he would have posted his tune. Maybe you should have a thread to step by step show people how to do that. I would think that would get people like us learning.

Because you are new and don't know what the hell you are talking about we'll be nice for now. 'Sweep was (the first person) trying to help 68 ZO6 as well as you with some of his spare time. Not all of theese cars are the same, so he didn't want to just tell you guys to do only what he had done on his vehicles with the possibility of leaving something out. (Some of theese PCM's tables are laid out differently, and from time to time use different OS's, occasionally.) It's also a rule of thumb around here, to post a copy of your tune when asking that type of question: 1. So we don't have to go pull a copy out of the repository ourselves just to answer everybodys questions individually - AND - 2. That way we actually can pretty much tell people what they have to change, what to change it to, as well as what tables/areas you have to click on to find where you should/shouldn't be making theese changes in a step by step kind of way - Which is exactly what he was actually trying to do in case you couldn't tell! And by the way based on your next response we will all be able to tell right away how much effort you have put forth into becoming familiar with this software, your tune, and how this forum is even designed to help you get nearly any question you need answered, given you actually try - a little. Good Luck!

Hey, dont worry about being "nice for now" because you just proved what people say about this site, "no patience for beginners". If you notice the OP never came back and neither will I since you are anticipating my next response. Please delete me or take me off the membership from this site.
