I took my car out on Saturday, day before got my 200 cell cats installed, IPD plenum, and Evoms CAI with AEM dry filter, and the Aluminum pedals.

Really great sound and no cabin drone!

Driving this morning CEL P0420 reset

This afternoon CEL P0420 and P0430 reset,

Looks like I will have to have the ECU done

Any recommendations? Softronic, Revo, GIAC?

Located in Edmonton, AB

Thanks

 

I am pretty sure it is not the pedals that caused it. Looks like the cats.

I went with the softronics and loved it. You gain a nice kick in the butt torque and the powerband is linear and smooth as a whistle.

 

Did you disconnect the battery to reset the DME after installing the parts?

 

No, I didn't, but I just put a new Optima 34 battery in today, so it so reset the ECU, will let you know in a few days, if it went away.

What's the differnece between doing a battery disconnect and if I erase the code?

Thanks

 

If you disconnect the battery it will reset the DME back to factory settings, from where it will optimize the settings for the improved airflow.

If you do not reset the DME it will detect a sudden, unexpected increase in airflow and will throw an error code. Resetting the error code will not cause the unexpected airflow to disappear and might cause another error code!
