Glad they answered you, I've had good luck with their customer support. Yeah, I bought a Ktuner from somebody on the civicx forums, put it on my 2017 Si and then swapped it over to my Accord all without any issues. Thats the great thing about Ktuner, as long as its unlocked properly you can use it on all those different vehicles. Enjoy your newly tuned Accord

I had an Si coupe with a toddler in a front facing car seat and a 9 year old and I had no problems with the space in the back. Just having to push the seat forward to get them out constantly sucked a little but the car was a ton of fun. Totally different car from the Accord. The civic is much smaller and it shows in the handling department. With the tune it was a real sleeper, I was running the TSP stage 1 and it was a lot. Running the Si in sport mode with the tune was awesome between the throttle response and the stiffer dampers. I can't compare apples to apples with the accord sport because my 6MT 2.0 sport doesn't get the fancy sport mode button. I will say I kind of knew what I was getting into the the Accord beforehand because my wife had a 1.5 EX-L before and I loved the way the Accord drove and handled for being so spacious. With having 3 kids you made the right call. The civic si is the best bang for your buck sport compact you can by in my eyes but the finishes, infotainment and comfort of the Accord punch above its weight. I love how linear the power is in the 2.0 with the ktuner on it, the civic died off at the top even with tunes far more than the 2.0 does. They're both great cars but I have no regrets moving from my si to the accord.
