The reflash has not fixed mine. I'm pretty sure it's not pinging/detonation either, but until I know the cause for sure I won't rule anything out.Is this a bad thing if it is true? I am not an expert but if a reflash fixes clacking then wouldn't that mean that the cause would have had to be pinging/detonation? And if so then riding all those miles with a detonation problem has likely done damage to our engines, no?
So...where's the report?Hay @Samg , suggest you read @Tom - AMS thread on possible cause of clacking. @Dwarf just ride the piss out of it. If it breaks during warranty, they own it. My 2015 has it. I switched over to AMSOIL full syn developed I/P. No noticeable effect on clack. I'm currently at 6k miles. I'm scheduled for stage II install on Tuesday so I'll report in
Interesting that an ECU reflash will magically tighten up inside tolerances causing piston slap. Like tune - up in a can.I got the ECU product update done and the piston slap noise it so much quiter.
I've done some mods since reading this...I've never had a "clack" but had some noise that is now completely gone. New PCV, wrapped OEM pipes with gutted cat and air cleaner. Sounds smooth as silk now.7500 miles (ish) and getting worse then. Very sorry for your woes man...not a good vote of confidence for the brand if they're not willing to stand behind it.
thank you!!!!You are right about an ECM update not being able to fix piston slap...but an ECM update can fix pre detonation knock. 500 plus miles since the update and my 2014 is much quieter. I have to listen very hard to hear the once very loud noise at light load throttle around 2200 rpm. And all of the steady clack under heavier throttle at 2500 + rpm is entirely gone. I did have the oil changed at the same time as the reflash, but hardly think that could be it since it was the 4th oil change in 12000 miles and the noise has been there since day one. Dealer said they used the same oil kit all four times....unless the oil change magically rebuild the motor
