Okay then, expect to send your particular IRC back to them. I don't think you will have to pay for anything more than shipping. I do know that I was comfortable with how it was handled. I wasn't told that they were aware of a defect at that time. However, the transaction went as it did for them to check they're product for what failure did occur. Then I was sent a new one and I installed it with no problem.
My bike is set up with a PC III USB, Ignition module, and a Dyno tune. I was able to run my bike without the IRC and still have the other components installed.
The IRC was installed after the Dyno tune. I had run it on a hot day parked it at my favorite restaurant, went in to eat, came out and started up, got going down the street and the bike shut down. I couldn't figure out what happened. So, I got some friends with a pickup to go to my house get my ramp and some straps and come pick me up.
I had just installed the IRC before this ride. That was the first thing I tried. Took it out of the loom. The bike started up and ran fine. I called DynoJet and told them my crying story and they said they would help. Hopefully you will get the same treatment. Please be patient, they do want your business and likely will help in this way.
By the way, if you have a similar set up, the IRC is a monitor and info device that allows the PC III the ability to refine its control of ignition advance and fuel regulation. It doesn't have to be there for the other DynoJet components to work. It is only a slight difference in power when working properly with the IRC installed.
I am happy to find out your bike runs good after this event. When, and if you get a new IRC, it would be nice know how that turned out for you.
What other components do you have with the IRC? Is that the only piece you have form DynoJet?
