Take a look at the FAQs... How to embbed any Application in RR ?
The skin i use, iDrive, has a button in the top right called "car data". It just so happens that I have a data aquisition program on my car that interfaces with my aftermarket ECU - I'd like to click on "car data" and have it open the EXE and embed it in RR.
Here is a SS of the application I run:

So where do I tell it how to open/etc?
This is actually one of the most basic, and simple tasks to accomplish in Road Runner. With just a small bit of searching, you most certainly should have come across something like this to answer you question.
You should realize that I've not been in the carpc arena for some time - I build ecus and between firmware and software with that and building my custom turbocharged 5 series bmw, I have been out of the loop for some time.
I searched around but the forum isn't the most organized and I wasn't able to find it. Sorry.
