check engine light after tune
I posted in here since there is more traffic. I recently tuned my cls400 to amr v3.1. I have catless downpipes and cls63 amg mufflers. This tune required shipping in ecu.
Once i installed the the ecu things were perfect for about 20 miles or so, then i got the check engine light po420 and p0430. I was informed that they no longer tune out the o2 signal due to federal laws. Wish i would have know that before i sent in the ecu. Any members recently tune and have any issues? If so, what o2 simulators were used? I also asked for info on that but have yet to hear anything. Thank you in advance

That is bad news for the tune crowd.... One of the reasons people go the tune route instead of piggyback is to remove CE
Is this the same on c43 guys?
