I installed the MCcruise on my 2014 R3T last week. I too have the canister on my bike (bought in PA, USA). I mounted the computer on the right side of the bike, zip tied to the ECU mount. I didn't bother removing the carbon canister for the install but will probably take it off in the future.
I am totally impressed with the MCcruise product. Fantastic build quality (looks stock) and EXCELLENT customer service. Install instructions are very comprehensive. It took me about five hours to complete the install and I consider myself a pretty experienced wrencher.
On a side note, I am having issues with the cruise control cutting out unexpectedly. Tony at MCcruise was very quick to respond and assist with diagnosing and correcting the problem. They are sending a replacement computer which they hope will resolve the issue. Despite the current problem with the product, I remain satisfied to date as they have been very good about making sure I am taken care of.
I may end up writing a more comprehensive review once all the bugs are worked out. It's probably the best aftermarket accessory that I have ever added to a motorcycle.
