Updating my survey from November 2019
https://www.civicx.com/forum/thread...y-survey-all-models.42361/page-16#post-710597

Vehicle: 2018 1.5T Sport Hatchback CVT

Total Tuned Time: ~15 months

Total Tuned Mileage: ~13,000 km (= ~8100 miles) and counting ... driven only in the warmer months

Tuning Device(s) Used: KTuner V1.2

Tune(s) Used: TSP Stage 1 with PRL CAI Race MAF tune (*Current*), KTuner basemap dual 16 PSI Econ / 21 PSI,

Fuel Used: PetroCanada 91, Chevron 94

Additional Engine Mods: PRL Motorsports Short Ram Intake w/ Race MAF (*PRL Cobra Cold Air Intake to Short Ram Intake conversion kit*)

Driving Style: Econ mode enabled or light pedal during warm-up, or slow city driving, while on Map 1 (basemap). Once warmed up, if feeling like it, I would change to the TSP custom tune Map 3. From looking at the data log, it goes up to 24 PSI. Speedy driving with aggressive bursts time-to-time, while maintaining in the 2500 ~ 5000 RPM range.

Tuning Experience: First time tuning on the Honda Civic platform, and on the 1.5T engine too.

Everyone knows that tuning improves performance. But what about reliability and safety? I created this tuning survey thread to document just that. Members can include pics, videos, dyno results and timeslips, if desired.

If you have a tuned 10th gen (or were tuned in the past), help the community and post your experience here. Civic Si, non-Si 1.5T, Type R, 2.0 NA.

Please use the format below when posting your information:

Vehicle
: 2017 Civic EX-L sedan

Total tuned time: 24 months

Total tuned mileage: 12,000+ miles

Tuning device(s) used: Hondata CARB Flashpro, currently using KTuner V2

Tunes used: Hondata +6 and homemade +7.5 / KTuner 21 / Customized TSP Stage 1 for non-Si (current)

Fuel used: Sunoco 93 Ultra (exclusively)

Additional engine mods: PRL silicone hose / aFe Pro Dry S filter combo

Problems/issues: None

Driving style: Slightly speedy with aggressive bursts from time to time.

Tuning experience notes: This is my first time tuning and I've gone from total tuning novice to now feeling comfortable enough to help others with tuning. I've never had a mod transform a car like tuning has. The main reason I tuned was to reduce the feeling of turbo and CVT lag when quickly going from light to heavy throttle. Tuning has definitely reduced the lag by maybe 90% and gives me a completely different driving experience. My car went from a peppy commuter to a bit of a sleeper beast. My mpgs are only slightly lower since tuning. Mostly due to a heavier foot. :thumbsup:

TUNED CIVIC X RELIABILITY SURVEY STATS (as of 4/6/20)

Total tuned participants: 231
Total tuned miles driven: 3,298,500 (estimated)
Most tuned miles: choo's '17 Sport Hatch (81,000+)

Tuned cars with major failures: 5 *
Percentage of tuned cars running reliably: 97.8% **

Transmission type: CVT (78); Manual (153)

Hondata used as tuning device: 59
KTuner used as tuning device: 185
JB4 used as tuning device: 1


Pro custom tune file used: 49
Most used non-base tune: TSP Stage 1 (84)

Most tuned vehicle: Civic Si
Most used fuel: 93 octane (121)
Popular mods: PRL Cobra, K&N drop-in

* 2 of the cars had failed CVT's (both replaced under warranty). 1 car had faulty injectors and a blown head gasket. 1 car blew an engine running an E35/meth setup. 1 car blew an engine on the racetrack.

** There were minor issues reported here and there with the stock clutch, an injector issue, some fuel trim and knock control funkiness depending on intake and gas used, etcetera. None of these issues were major.

Survey Notes: From the surveys taken so far, base tunes (on a more or less stock 10th gen) appear to be safe. Properly tuned, adding bolt-ons can be reliable, too. The issues seem to happen mostly when power output is pushed too high, owners attempt to self-tune, the car is continuously driven to the limit (like on the racetrack) or it's been abused. - gtman

How long have you had the Mishimoto oil catch can?
Any comments / user review you would like to share?
I've been thinking of adding that for my hatch for the last couple months...

Vehicle: 2016 Civic LX sedan 6MT

Total tuned time: 2 months

Total tuned mileage: 5,000 miles

Tuning device(s) used: Ktuner

Tunes used: Base Map

Fuel used: 91 (Mostly Costoco, Fastrip, and Arco)

Additional engine mods: RV6 Catless Downpipe

Problems/issues: None

Driving style: Lots of highway miles and spirited city driving

Tuning experience notes: I disabled my CEL through Ktuner and I haven't gotten a CEL since I installed my downpipe. This is my first car that I have ever tuned and I have to say it's been awesome! One slight problem I have seen is sometimes my car kind of lurches at 2.8K-3k rpm in either 2nd or 3rd gear when I drive slow. I assume that this is a tuning issue since it popped up when I installed my downpipe. An etune or a proper custom tune could solve this.
I have the exact same issue, thought I was just overthinking it..

I have only had it for a few months, but so far I am seeing it catch a little bit of blow by fuel vapours and oil. I make sure to check it every month. I pretty much have it as a preventative. I know from past vehicles that were direct injected, the engine got pretty gunked up when they had a lot of miles on them. So to prevent this I decided to put the catch can on right away. People will warn of the can freezing over in the winter but Ive never experienced this. And I live in An area that gets really cold winters. I just make sure to check it more often in very cold temperatures.

Thanks!
I plan to get for the same reason -- as a preventative.
Us in the B.C. west coast don't get the nut freezing winters Ontario gets ;).

Just out of curiosity, where did you buy your oil catch can from?
I know you can order it directly from Mishimoto, but just seeing where another fellow Canadian gets his Civic parts from.

Uhhhh YEA! Lol... I keep up with the California special crowd killers(460hp).... until about 95mph .... Don't worry man, I freaked out when first tuning it... and even felt bad.... but I have been tuned for over a month and no abnormal issues. If you are worried about blowing it up, get the K-TUNE v2 so you can watch your knock control... ,49-.59 is a good range. it should stay at .49 though. If you get knock counts then your fuel grade may not be all that great with the tune you choose.

Just keep this in mind, the engine is rated for 20.3psi and is guaranteed to operate normally within those ranges for the most part depending on your fuel and maintenance. The extra 3psi is not much of a risk if you look at it like that.
