How to fake out your engine ?-catalytic converter
« on: March 07, 2010, 09:33:32 PM »
Since I should run real synthetic racing oil in my engine which seems to ruin the catalytic converter,how do  you delete the converter without getting engine warning lights?  Secondly, How long will the cat last if I am using racing oil? I do have solid lifters[posts]in this engine,

You can turn off the MIL light for the associated codes with a catless down pipe. I will take a look at my ECM with HPT to see if they are there or not. It will be few days as the car is on stands right now getting tweaked for the Solo season.

I've done what SOB posted.  Using HPTuners, download the tune, find the code and turn it off, then update the calibration info to the ECM.  I believe the code is P0276?

Are you using a high-ZDDP oil? Even that won't kill the cat THAT quickly. Just keep the damn thing in.
I've been using Redline in several different cars from new for 10 years and have yet to see any issues with catalytic converter life or effectiveness.
