Its simple numbers.. P31/pp entails an additional 30hp. The factory pp tune becomes obsolete when you use any aftermarket tuners tune as the pp tune is still mild.. Approx an 80hp gain for non pp cars and still a 50hp gain for pp cars. For me, having my 2011, the pp wasnt worth it being there no suspension change and because I always tune my cars, paying for the additional 30hp wasnt worth it.

Glad you are enjoying it!!

what kind of rear diffuser do you have?

I had very similar gains to this. Keep in mind that I'm at 6500' elevation for my lousy times. I averaged 13.7@102 bone stock 2012 non pp, and went to a 13.2@108 average after a 91 octane tune was introduced. I'd guess a 93 octane tune would be even more, but for simple timing and fuel re-mapping, those numbers are insanely satisfying. Taking off a half second in an already "well running" car are similar to my results from adding an 80 shot of nitrous on a Mustang I once owned, wich actually costed less than the tune, but I bought a lot of the actual nitrous, so the cost gets worse and worse. Sorry for the long reply, just trying to convince people who are undecided on going with a performance ecu tune. THESE CARS RESPOND VERY WELL!!

I'll chime back in with a seat of the pants meter on headers and tune tomorrow night, if I get home from work early enough to finalize my MHP header install!!

I'm new to this forum but wanted to share my experience with the Eurocharged V4 tune for my c63. First off its amazing it really wakes the car up and the shifts are smoother and ppwer is significantly up and very noticable. I bought my tune through Jerry and Philip and can't say enough positive stuff about my experience. They were responsive even over the TG holiday and usually responded to questions within an hour or so. I got the mygenius along with the tune and while its clunky and the actual steps are not exactly the same as those posted on there site it was easily enough to do even for someone whose not the most tech savy. It took about 2 hrs all in as I wanted to be sure I did everything correctly and took my time rereading the steps and watching the video but the actual plug and play in the car didn't take more than a couple mins. Best thing is everything is done through the obdII port so unlike other tuners no need to break open the ecu which is a red flag for many dealers and its really easy to map back to stock for when you need to bring the car to the dealer. I've tried and it works flawlessly. Know more on the fun stuff. Down low there isn't that much a difference but once you get to 4-5k rpms you really feel the increase in power and torque I was at crazy speeds in no time and have only driven the car a few times all of which on city roads. Also while its not a huge difference the exhaust is louder than before the tune which is always nice. If anyone has questions let me know I'd be more than happy to share any other info needed. To the guys at Eurocharged, nicely done!!!

Get straight pipes or LTH and your mind will blow even more

Jerry does a great tune and his customer support if fantastic. However, some 63 ECU will not accept the dimsport hand held tuner. This is not the fault of Eurocharged and there is nothing wrong with your car. It just happens. The alternative is to have it pin tuned without opening the ECU case. The results are just a stunning but you can't switch back and forth whenever you want.

I dyno tested mine today as well. Maybe I should've put the results here instead of making a new thread. Oh well. Here's the thread.

Is this a random, car-specific problem or is it broader (i.e., does the non-acceptance problem affect a certain model year, etc.)?

crazy1eye

Yes it seems random, saw a 2012 not accept it then my 2010 didn't accept it also.

Have existing Eurocharged v3 owners had any luck getting an updated v4 tune?

Autosport7

Congrats OP.
I'm in the same situation, can not grab traction, especially with the milder temps right now. I am thinking next up for me is Quaif rr end and rolling fenders to fit some 275's out back with spacers. Maybe adding some more rubber to the ground and a different compound than my current set up will help out.

Vegas_AMG

Yep v3 to v4 las month during SEMA. I noticed a difference right away, shifts are way smoother on mine.

loungn14

FYI we are holding our sale pricing of $850 shipped for the tune and handheld through the end of the year! Get them while you can before prices go up!!

SF_C63

Who should I contact to request an updated v4 tune? I never received a response from Sales via email.

SF_C63

I reached out to Sales again and received a response almost immediately! From there I forwarded my stock ECU tune and received an updated tune in no time.

I think previously I just tried to reach out to them when people were on vacation, or the email probably got buried because it was sent after-hours.

Thanks Eurocharged!

Eurocharged my C63 yesterday. Car definitely pulls harder. Shifts are now much much quicker IMO. Although not quite as fast as my ISF (comparing true autos to one another), it is now much more pleasing to shift the car in manual mode. Previously I had felt such a huge delay that it reminded me of some of the early 2000 vehicles which just came out with "sport shift". The way the car shifts alone is almost worth the price!
