Cylinder 8 misfire engine light

Yeah the tune turns the rear 02 off

Just so there's no misunderstanding, you two different Tunes or one?
One for no cats (O2s off) and one for cats (O2s on)

Hi-Flow cats with a Tune with O2s on usually require rear O2s spacers.
Running cats with the rear O2s off could pose an issue, maybe.
Never heard anyone doing that.

I'm sure you discussed all that with JDM.

 

[BRAPPPP]

Just one. 02 off. Used for cat and no cat

 

[MTF]

Interesting.

 

[BRAPPPP]

I have high flow aftermarket cats so they leave rear 02 turned off. So that same tune will work for the straight Y. I just called JDM and they said it shouldn't be an issue.

Throw the offroad Y pipe on.
It wont pass inspection either way.

 

[BRAPPPP]

Ha the last thing I'm worried about is passing inspection right now.

Hey I'm taking cats out now. I noticed my exhaust clamps were super loose like hand tight. Maybe that could cause 02 miss reading because of vibration?

Everything looks ok. Well at least you know the cats are the honeycomb type.

Were you able to switch the two fronts?

You have to be careful with those wires, they are very small and easy to brake.

Yeah they got kinda twisted up when loosening them. No I didn't switch them. I'm putting in the straight pipe right now tho
