    Tuned since it August, it has been an awesome 10k miles!

    Started with the Starter 21 tunewith the OTF maps for a few months and then tried out Stage 2 in November. It has been really good but I think I'm going to swap back to the Starter 21 with the IAT corrections @gtman shared a while ago.

    Hopefully this will keep my knock control down when it starts the weather starts to heat up this spring and summer. I've been in the 0.5-0.6 rangr ever since the weather cooled down too...

    Damn 91 octane California gas :banghead:

    Ive been trying to find info on boost by gear but having difficulty. Is it a program you download, something you buy? I purchased a ktuner and read somewhere boost by gear will help to not murder the stock tires.

    It's in one of the sub menus that you can get into on the left side when you're configuring a tune. I don't have it open right now but I remember it isn't very hard to find. Maybe it's in or next to either of the quick adjustments or quick enable sub menus?

    Yeah. Boost by gear is extremely easy to add. Honestly, unless you floor it from a standing start often, it's not something you have to do.

    Btw, I'm often asked how a tune cuts into mpg's. Well during the cold winter months, I couldn't take a picture to show how mileage stays basically the same (with similar throttle input). Cold weather kills mpg. This morning though, it was a balmy 59 degrees for my 10 mile 60/40 highway/city commute. As you can see, 41.7 mpg is pretty good. :thumbsup:

    Well, I got my KTuner delivery and set everything up. I would say everything went just as I expected. Very easy to follow the instructions online and then after I flashed with the 21 tune, my dashboard lit up like a christmas tree like everyone said it would... especially with all the sensing assistance stuff on my Canadian model. After running some errands and making a few stops, all the lights disappeared :)

    The one thing that happened that I wasn't really expecting was... holy crap this is a totally different car! I found my way to a back industrial road and wanted to see what this thing could do... my car was skipping across the pavement when I hit the gas. Safe to say my winter tires can't handle it!

    Oh man... I'm excited to drive to work on Monday now!

    Remember you can use boost by gear in the lowest "gears" to account for your tires lack of grip.

    I got a high speed ticket before I even got my Ktuner, which should arrive early next week. 21+ for a year, on a CVT? And everything is still all good on your car?

    Yes, all's good and she's well broken in with 50k+ miles. I've got selectable 3 tune going on now. Been playing the tweak game with lower mid range on up with the Starter 21 for a top tune here and there. I listen for changes and I notice things with each adjustment and I monitor with Tunerview.

    gtman is running the Factory/21psi tune I believe and has all of the Quick Enables at their highest, except for RAMP (which I believe he keeps at Improved II).
    At those settings the boost doesn't climb as quickly and he can remain in pretty much in negative pressure values during his drive - thus, the fuel economy.

    To respond to the 21psi safe for CVT question:
    The 21psi is what the compressor is doing to reach the target. You will see about 17.5-18psi from the MAP at peak. The CVT will transition into the appropriate gear based on load. Besides, the base tunes are well below the CVTs capability.
    BUT - if you throttle hard from dead stops frequently, anyone can damage ANY transmission sooner with or without a tune.

    Thanks for replying to me. I am new to tuning. I read gtman's journey from Hondata to Ktuner and that's what made me decide to try Ktuner. I love my car, but didn't intend to buy this one, but the dealer couldn't get me into the 2017 V6 Accord coupe I went there for. He put me in my Civic Hatchback Sport Touring. The car is great, but I knew it was way more capable than the stock settings. This forum is great and the stuff I learn on here is priceless. Thanks.

    I told JR from Ktuner I should probably be on commission because a bunch of members have said my posts turned them on to buying Ktuner.:) Before that, I enjoyed my Hondata tuned car, too. It's just that Ktuner offers more. It takes a really nice daily driver and adds a bit of muscle. It makes passing and merging effortless. It reduces lag. Although it seems expensive, the power to $$ ratio is lower than any other mod out there. Plus there are so many adjustments available it's much more then a single new tune. You can tweak here and there and change the driveability a bit with a few keystrokes.

    One thing I’m trying to understand is if the tunes are safe why does everyone monitor there cars sensors so closely after the tune?

    Some people monitor all the time, some don't. I only monitor mine right after I upload a new configuration to look for any "weirdness". My Ktuner doesn't stay in the car. It's not a must do. People mainly monitor knock control which can mean various things (bad gas for example), IAT's and fuel trims. Monitoring is in no way a reflection of the base tunes being unsafe. Fact is, some people enjoy monitoring parameters in untuned cars too.

    On the other hand, you can certainly add a base tune as a "set and forget" thing if you like.
