Re: 02 simulators
No but you can get a custom tune to delete the 02 readings. My car as of 3 days a go has on cats on it and no check engine light. I can tell you where to get this done if you want. My cats were craping out on me and throwing 02 codes so we deleted them in the fall. Ryan
Anyone ever run one of these on their cars because my 02's keep going bad on me.
Which O2's keep going bad? Fronts or rears? Sims are meant for the rears to keep from getting codes after yanking the cats. The front O2s obviously can not be eliminated as they are needed for monitoring the A/F ratio of the engine.
Rear sims were always a pain as they tended to crap out and be generally unreliable. The easiest method is to get them edited out with a custom tune, which will remove the SES light and allow you to still meet the OBDII emissions test, if needed.
