Question about tunes
Hi all,
When it is time to smog your car will it pass the smog test with any of the ECU tune available to us today? Also what if you got a tune that disabled the secondary O2 sensors and put back your stock mid pipes, would this pass the smog test? Thanks, Jans Last edited by jans; 08-26-2009 at 06:54 PM.. |

1) Change the thresholds in the code that compare pre and post cat o2 sensor voltages. 2) Turn off the o2 sensors and emission monitoring completely. Remember this is for offroad use only
