Yes
Even in a case like this with a flash tuner. If you pop the motor at 6K RPM its going to det pretty hard. If you flash the ECU back to the stock tune and tow the car to the dealer and throw your hands up you can be sure you will be caught. The first thing they care going to look for is the codes that caused the motor to blow. What RPM it went and why.. ect... When they find no codes and they will surely know something has been tampered with.
I know you answered this with "100%" but Im curious to know some more details there, guessing many others who will buy ultimately would want to know too.

Thanks for all the kind words!
The device is $450 plus the cost of the tune. If you have an exisiting EC tune on the car, then you will only have to pay the $450.
I will provide up to 4 tunes at no extra charge. This includes tunes for Race Gas, Nitrous, Pump, V3, BETA V4, Catless, etc.
The ECU had to be opened previously because of encryption, access codes, etc.
The dealer will 100% not be able to tell that the ECU was tuned. :-)

has that been verified? if so thats huge
so really, with a tune that doesnt change the rev limiter, its significantly harder to detect if not completely transparent since the ecu will never record that it exceeded factory rev limitations

With the Falcons here in Australia, the dealers could still tell. They had to be looking for it though. I'm thinking there are tell-tale signs that would suggest that parameters have been changed.

but only if they hadnt been changed back to stock parameters before service, right?

This is what I'd like to know also. It's my understanding that the ECU stores certain values - throttle %, RPM's, speed, etc. If you flash back to stock, all the "settings" may go back to stock, but doesnt the ECU still keep these values, so that when a manufacturers rep comes in and really digs deep into the ECU, wont they find that? "Sir, I see here clearly that throttle % has gone well over 100% - how did that happen?" type thing. You guys are way more knowledgeable than me - can you address?

no, apparently they could tell either way! The tuners would say there's no way they could tell, Ford would say they could tell. Mind you, on all the forums I never had an instance where someone was caught out.

Use the tool for that it is. A great way to flash on your own without cracking open the ECU.
Dont think you are fooling the dealers though. They will know its been tuned. Just the time stamp on the file when the flash was loaded would be an indicator. I am no expert in ECU tuning but I know systems and there is always a trail.

2012 C63 AMG Sedan
Newbie here with a 2012 C63AMG Sedan...LOVE the car! I am going to buy the EC handheld programmer and the EC V4 tune...Also found out from Jerry that the V4 tune is stable and will be publicly available this Monday next week!
As per Jerry, faster/ smoother shifts, higher shift times! No dyno chart just yet but on the way!
