So who is tuning cpc units in america right now or does anyone know if any of the main tuners are working on it? I know there was a post made on it and i contacted renntech since they tuned my car but they havent reached out to me yet on cpc unit. I have a pretty conservative tune and not looking for anything crazy. Pretty much gonna tune the cpc the same if i get the chance.

I have a tuned CPC, if you want one, msg me.

Dont buy anywhere where you dont see results. Many claim they have CPC, but in 60-130 numbers they slower with turbo upgrade then Stage 1 on other tuner.
from what I can tell, without CPCNG tune, 100-200 times are 6.9s
with CPCNG tune, 100-200 times are 5.9s
literally 1s saving, about 15% faster than just a stage 1 tune alone. stage 2 + cpcng + downpipes combined is probably closer to 30% faster than stock...
i saw a graphic that describes the torque limits in the RPM ranges of the CPCNG
it sets a 900nm limit (663ftlb) max. with tune, we should being making more than that.
for $2k, i would highly suggest a CPCNG tune. unless i've been grossly lied to (so yes... let's wait for dragy confirmation), it's a no brainer
the only problem is, it is only german retailers right now.
you need to pay €1,800 before VAT/taxes/shipping, then you need to install the unit (you can not just flash over OBD-II). i personally have no clue where the unit is in the engine bay (or if it is even in the engine bay, and i've looked for it)
i am still actively working on emulating the continental bootloader for the CPCNG so i can find the UDS 0x31 signature validation routines and try to spoof them, but as you can imagine, emulating autosar rta-os is non-trivial. even being off one bit in some places throws the entire application into an infinite loop.

Yes ... one friend of me only have ECU Tune and about 700hp cranck.
Other one have ECU and CPC and about 780hp.
Tell that our friend ronin
Guy is an obnoxious old boomer you can’t expect him to understand that something called a Central Powertrain Controller would have a marked effect on power output on the street.

I think we get that the CPC tune can make a difference at high speed that a dyno can't reflect. However, that has nothing to do with the power output that a dyno CAN document. It's fine to say "this 780 hp is more usable in the real world than the other guy's 780 hp." That is not a reason not to document this 780 hp in the first place.

I absolutely agree. A dyno pull is typically full power through the closest gear to a 1:1 ratio, whatever that may be. The CPC modulates power output when shifting, turning the wheel, in lower gears, etc. The dyno is just the wrong tool for the job. Dragy results through multiple gears will show you the difference.

So ya wanna show me the engines you have tuned that are compound charged using a dual fuel staged injection system..
Or maybe just one turbo only setup with varying boost by gear, RPM and engine load with anti-lag.

to be honest, it isn’t even high speed. if you are trying to make more than 900nm of torque in any gear at any speed, you will electronically be limited without a CPC flash. at 0mph or 100mph. i think stage 2 CPC tuned cars pull 0-60mph in like 2.7s
why don’t you just drop $2k for a tuned CPC and enjoy a 15% faster wagon? it’s a win win. you’ll become a believer and your car will be faster. what’s the hold up?
“darn newfangled kids and their new components to tune? i don’t understand ‘em! gimme a carburetor and a hemi and i’ll be good to go! i’ll even tune ‘er myself!”

What do you know about tuning **** ant ?
Your future awaits...
Okay Boomer, do you need me to explain to you the difference between an ECU tune and a CPC tune? You’re now conflating the two, proving my point that you are just completely out of your depth here, I feel like I’m trying to set up my dad’s internet again and he keeps asking me if it’s going to be taking up the phone line. OF COURSE it’s a good idea to tune your ECU on the dyno, the CPC is an altogether different thing you absolute buffoon. This is exactly why I wanted MY ECU tuned on a dyno and not with a canned tune. The CPC value changes are felt under load, on the street, with acceleration data to prove it.
What do I know about tuning? I learned it all on the dyno with this baby.
790rwhp on pump with a stand-alone.

What is it ?
Oh yeah do you own a AMG E63s ?
You didn't tune it or did you build it, did you ?
Writhing checks is not tuning....
Real tuners don't tune on the street until something fails, it's a little too late to dial things back while waiting for a tow home...Load values on the drivetrain are there for a reason.
You can't get sustained load in a particular RPM and throttle position on the street unless you are doing your tuning on Hwy 15 on the Baker grade from LA to Vegas climbing up hill, over and over again..
I know because I did my hot weather street tuning in 115*f -120*f ambient temp there as my buddy typed in the corrections I wanted as I drove..
i am working on vmax variant coding solution still
VDIAGTOOL Code Reader ELM327 USB Interface V1.5?Version Read and Clear Fault Trouble Codes Check Engine Light OBD2 OBDII Car Auto Scanner Diagnostic Scan Tool Cable for Laptop PC Windows 7 XP 32 bit
I'll stay outta this conversation for now but will be back to laugh my old *** off when the drivetrain failures are posted up for all to see..
Have fun kids...
I just wanna clarify one thing for you.
You have 2 AMGs, right? The AMG GT and an E63S wagon, right? I know you said one of them is tuned.
So, you purchased money to "tune" your car aka increase its power. aka, you aren't afraid of upping boost/fuel/timing a little bit for some more power and fun, right? aka, you aren't afraid of your drivetrain exploding off of a stage 1 tune, right?
ok, well we are LITERALLY trying to tell you, you wasted your money on that tune. there is a SECONDARY electronic unit preventing ANY tuning/torque increases from happening in the e63s, and it is called the CPC. why are you fighting us so hard on this? we are trying to help you man. we're a community talking about making our cars go faster, that's all.
We aren't going to watch our drivetrains magically explode because we up a torque limiter 10-15%...
if anything, tuners should be laughing at us because they know an ECU flash really doesn't do **** when you have a module sitting between ECU + transmission + engine limiting global torque output...

ouch! This really hurts....
there was a post not long ago, when somebody was denied warranty repair because of ECU tune....

No before and after hub dyno sheets, it didn't happen...
