Most of the time it is a better idea to not say what is going on around here, (even to our beta testers) until something is ready, what might seem like a simple task can turn in to a nightmare real fast and long delays can happen.
The simple fact is that Cummins have high levels of security on the 2010 - 2012 ECM's to stop them being tuned (2013+ is even worse as they have closed all back doors), it could take us a long time to get these ECM's to play ball. Unless you are dealing with this process first hand it is kind of hard to appreciate what you can come up against, we could spends months doing only this and never solve it.
