So the car made 456 rwhp uncorrected. What was the SAE correction factor? When do you plan to add the tune and redyno? Lastly, what is "dyno mode"? I may take mine to dyno her later today.
What was the octane level used in developing this tune? Some of us in the US (California, for example) can't get better than 91 AKI without hunting down Union 76 stations or paint stores.
Dyno mode disables traction control, abs, etc. it also shows a primitive readout for IAT, and some other stuff - i didnt dig deep into the menu.
Dyno mode
-press the start/stop button once
-ensure you are on the the current and total mileage screen
-hold the call and ok button for 5 seconds
-press ok to confirm
You are now free to dyno, drift, etc.
To return to normal, i just cranked the car and press "ok" to exit dyno mode
Not ours, we do lots of testing including sending cars and ECUS back to AMG for checking.
All clear
Next time you will tell us you get your tunes directly from Affalterbach or some other
I am sure there is a good reason for being THAT silent for so long
@detschlandFan: I am "all in" you ended up with clutch slip issues on your car and the high risk of getting it fried or maybe even the transmission ****ed up if the posted torque trend (over 800Nm at 3000rpm) is what they deliver with a piggy (not talking about a proper ECU tune). No way this was tested all over, unless they mean proper R&D is posting results from a few runs at some German dyno they never saw with their own eyes (@MTB obviously)
My colleague has a C63 BT and tried 4 different piggybox units here in Germany now, all the same ***t !!!
Put any current Piggy on the M177, put it in Manual, 4th gear, 2000rpm and floor it -> you will know what I am talking about.
I had a similar issue with a piggy on my former CLS63 BT and another friend of mine who works at AMG told me why I had to get the clutch to be replaced after only 12.000kms!
In the end I went with a proper ECU Tune by RENNtech (this was the first time with them) and never had this issue again with even more torque and power than with the piggy.
This is just another example from Rebellion of thinking marketing would be R&D... so, you have the C63 tested all over? Why posting posting AMGs press pictures?

Your words are hard to follow, so i want to make sure I am understanding you correctly - are you speaking from personal, 1st hand experience stating that your friend had transmission failure on a M177 C63 (i dont know what a BT is, my apologizes) from a piggyback tune? Or from a Rebellion Auto piggyback? Or from a MTB piggyback? Please elaborate and provide links, pictures, etc. i was unaware of that many piggybacks on the market already.
i can't, at this present time, think of a time where i would be in 4th gear, 2000rpm, and need to floor it? It takes a split second to downshift (depending on driving mode). The car has good torque down low, even without boost i can blip the throttle if i need to accelerate "reasonably" quick for whatever reason. If i need full throttle im dropping multiple gears, until im at or around 4000 rpm for throttle response and boost. Eh well thats how i drive anyway lol.
Not here to debate marketing or R&D difference of opinions between vendors or disgruntled customers. I just want a safe, effective increase in performance that can be quickly and easily be removed if need be. If you have evidence to support claims otherwise, please share.

Well, I fear that if I will share ALL the info I got from my AMG friend I will feed the piggy tuners on why there will be issues and HOW AMG can figure out a car was tuned with a piggy and so far...
No damage to the C63 transmission, I personally had a fried clutch due to a inproperly programmed piggy on my CLS63 BT (BiTubro) with MCT and my friend tried 4 piggys out on his C63 BT (BiTurbo) and all had the same issue. Thank god nothing was damaged because he took them out immediately!
Fact is: the pressure on the clutch is depending on the torque the ECU "thinks" to have... So, with a simple piggy the TCU is still getting wrong (stock) torque figures. And the MCT is "special" ...
Somehow I don't understand, what is it about to have XXX torques at 3000 rpm if you never use it?
BTW: same issue I am talking about will happen if driving uphill in C and half load ...
In Germany there are already like 6 choices for the piggy, back at the time my friend tried there were 4 and all had the same issues...
