Don't want to risk seeing a cel. It's annoying. Just going with catted, likely the powerneedy.

Older JB4 software could suppress the cel. In order to stay legal, they no longer offer that on newer software, unless your country (Canada) doesn’t require it.

That is the difference....it did in the past prevent a light, new JB4s and those with updated software will not suppress the light.

With that being said, the fabspeed spacer has prevented me from getting a light.

You used the 90 degree one? Still working for you?

Interested in know if those who used spacers were able to avoid a CEL since install. Been reading that the spacer helps, but CEL still pops up from time to time. I don't have emissions so I'd much prefer catless, but also don't wanna see a CEL/have to erase it each time.

Is it weird that I'm getting the "o2 sensor stuck rich" and "p0141" CEL code and I got it dyno tuned?

for everyone have CEL issues after flash, remove the Fabspeed o2 spacer. I had CEL come up even after flash, and once I got rid of the fabspeed o2 spacer, no more cel

Yes, but they confirm that before sending it out. They are just trying to operate within the law.

I live on the Canadian border and was hoping that would get me around the issue. It didn’t, but the 02 extender has been good for me.

Question, can BMS send the jb4 software if we are in Canada and do not have that emissions law?

Which simulator /defouler are you running and do i need to plug into o2 primary or secondary? Since two go back into the downpipe.

I'm also running the titan catless downpipe
