Can someone check my logs for me please!

 

[Terry@BMS]

Seems fine, next stop map2!

can you guys tune out a o2 sensor? i put on a downpipe the other week and i can’t get the code to go away

 

[Terry@BMS]

No it's illegal in the USA to bypass emissions equipment. Can't help you with that. The good news is the CEL in dash won't impact tuning or performance at all.

 

[trenton859]

it’s impacted my launch control, my engine is in limp mode because of the sensor

 

[Terry@BMS]

What codes are stored, exactly?

 

[trenton859]

0038 and it doesn’t give a description but it’s the o2 sensor, and the car cannot do launch control anymore due to the sensor

 

[Terry@BMS]

If you have an o2 sensor fault stored you'll need to repair it for the vehicle to operate properly. p0420/p0430 are the emissions removal codes and the only codes you should have with dps in place.

 

[trenton859]

so do you recommend replacing the o2 sensor?

 

[Terry@BMS]

Normal diagnostics would be to isolate the sensor triggering the code, swap it over to the other bank to see if the code follows, then if so replace it.

"trenton859" - 2018 Kia Stinger 2.0L with JB4, Maintec Downpipe (Catless), Jun B.L GT Catback exhaust, HKS BOV, Velossa Tech Big Mouth, K&N Typhoon Air Intake, ADD W1 Catch Can V3, Rokblokz (Mud Flaps)

So you are doing the downpipe on the 2.0? I have the 2.0 as well but although I can see a benefit, I would be hard pressed to tune at that level on the 2.0. Now, that being said, I can see going that far with the 2.5 coming out.....because you start out of the gate with 300HP.....

On a couple other forums with folks going with downpipe(catless) and jb4, they have mentioned a "spacer" on the O2 sensor to allow the ECU to get a proper reading. This may not be applicable to the Stinger...just throwing it out there.
