    Question C63 2011

    Hey, I was wondering if i buy ur hptuner for the Mercedes. Would i be able to use it to turn the rear o2sensors back on in the tune file?

    Currently my car is tuned by eurocharge v5 tune but i can't pass smog here in CA because the rear O2sensors are turned off.

    The problem you will run into is that you can not read the Eurocharged tune to adjust it. You will have to write a brand new tune to the car with HP Tuners. I would contact Jerry at EC and tell him you need them on for inspection otherwise you are starting over from a tuning aspect.
