I wouldnt say the tailpipe is worthless. Its still a good tool to get an idea where your at. As far as wideband sensor placement pre vs post cat, Ive seen .2 to .3 leaner for a post cat sensor vs a pre cat sensor. Taking that into account, AND the fact that your using a tailpipe sniffer, you will still get a decent idea if your running abnormally rich or lean. I think we can all agree that trying to dial in a car through a tailpipe sniffer is not the way to go but the OP is not doing that

Never understood why people don't log air/fuel when they dyno the car. Very useful tool to diagnose the simplest of issues. Just stick the damn sensor in the tailpipe
Impossible to diagnose without knowing many other factors but my guess is your running a tad richer throughout the entire powerbad but who knows without the a/f log

Which is unfortunately common with the v7 tune because it runs a few more degrees of timing and its supposed to be a tad leaner then previous versions. Which is exactly why a lot of people have been losing power up top (probably pinging). 93 octane is like the minimum for a v7 tune. But the op's graph is very smooth with no jagged dips so it appears to not be pinging. But more parameters need to be logged in order to be certain

C63 estate PPP
same here pinging when i slam the throttle. Had my 2012 PPP done by MSL in the UK a couple of weeks ago but haven't had a chance to do the 4 hour drive back to have it checked. They say mine is the only one they've had this issue with V7! Seems its more common than they let on. Did you get yours fixed?

Not believable. The numbers are fixed throughout the entire rpm range. Impossible

93 is the only oct I run.
It pings in high gears under lets say 3k rpm when there is load applied , it goes away in higher rpm . But I might not be able to hear it since the car gets louder.
I am not the only one having this issue , iv heard of others having this issue as well.

im having the same issue but only i have the V6 tune and im feeding it with shell v power which is supposed to be 91-93 octane. It happens in both S and C mode.
i might load the stock tune back to see if it happens.
i wonder if this is fuel mixture issue or timming issue.

Vlad and Slav save the day!!!
I was contacted by Eurocharged Canada and will be heading to their shop to check out whats up with my tune.
Very happy so far with Vlad from EC CAD customer service as opposed to EC USA which failed spectacularly.
However as of this post I am still waiting on my refund.
Sad that EC USA denies any problems when I was pointed out many different posts about the same issues I've had fellow members since my OP.

I’ve since been to eurocharged Canada and met up with Vlad and Slav. They properly tuned my car (at their own expense) and saved my faith in the eurocharged international name. I now highly recommend anyone to go see these guys was worth the trip from Montreal to Toronto for me. The car pulls hard and does a nice 11.6 1/4 mile a totally different beast! Vlad and Slav you kick ***! 😎🏎
