I can answer this one TC, Carl confirmed to me today they reset the flash counter so it wouldn't be obvious to the dealer
He also believes that this could be one thing the Revo software does that the others don't
....Playing Devil's Advocate here, but isn't this 'reset the flash counter' method the same principle which has been extensively discussed all over cyberspace regarding remapping the ECU and largely shown
not to be foolproof if VAG did a specialist investigation? It doesn't really matter imo whether aftermarket software is detectable or not - I believe in a policy of being honest in such matters.
Certainly at this early time of DSG remaps, it's hardly likely to become an issue but we don't know about the future.
Another question is whether a battery disconnection resets the Revo DSG remap to oem. But judging from Carl's earlier post about this, I think it doesn't do this on Revo's current softwarez.
