- 2018 Civic Si
Vehicle: 2018 civic si coupe
bought at 28K miles, currently at 45k miles
34.8mpg - pre tune(17psi)
31.4mpg - after new sparks, reflash of tune(23psi), thinking of ways to improve it other than passive driving
Fuel: 93 Octane - Costco, Shell, Sunoco -
Driving Style: SPIRITED DRIVING! I wish I could track...
Installed Mods:
Ktuner V2
Injen Short Ram Intake - convertible to Cold Air with extra tubing I have -
Mishimoto Intercooler
Akebono Front Brake Rotors
Muffler delete... - will get an exhaust eventually -
Purchased but not installed Mods:
FK8 Stage 1 Exedy OEM Clutch
RV6 Retrofit Flywheel for FK8 Clutch Kits
Eibach Sportline Lowering Springs
Injen Cold Air Intake Tubing - summer time conversion -
Tuning Device: Ktuner V2
Tuning Information: Basemap tune - 23psi boost with improved launching and throttle response
Personal tuning adjustments
-Traction Control System's Ignition Pullback for more aggressive driving
-Lowered Fuel Cut Delay timing for less "rev hang"
-Adjusted MAF table values to correct STFT and LTFT after Injen Intake installation
-Throttle response on the most aggressive setting
Personal Concerns and/or Maintenence:
Engine Cooling - Ever since spring has came in recently, I have had to watch my coolant, IAT and IAT2 temperatures. I for the most part keep an eye on my coolant to make sure it doesn't exceed 200F because I feel uncomfortable for the car being at such a high temperature. If I idle the car long enough, or sit in traffic long, I do notice the ECT temps to reach around 210F which scares me even more. Often I will have my radiator fan run via A/C unit. I will then just watch the temp drop to around 170-185F. I do plan on flushing my coolant completely in a bit, maybe even getting a koyorad radiator in the future before I get a downpipe. Hopefully fresh coolant will make my car happy and cooler than it normally would.
Engine Oil - Full synthetic 0w-20. I change my oil every 5k miles. I do check it sometimes, probably at the 2.5k mark. Sometimes it already looks due at 4k mark. Oil changes do help a lot with performance and just how smooth the car runs in general. No concerns other than if I need to run a thicker oil for summer times or for frequently hitting boost.
Transmission - Flushing oem trans fluid soon for amsoil!!! No concerns other than not being able to downshift to 1st sometimes, and shifting into 3rd in general. I used to have 2nd gear grinds sometimes but it takes time to just not grind it.
Brakes - Full front sets swapped because warped rotors from excess heat - steep hills that even 2nd gear could barely engine brake enough, 1st gear too slow - Rear Brakes soon to swapped for aftermarket sets
Spark Plugs - Replaced them a couple days ago actually. I believe right before I hit 45k miles. It did make a bit of a difference. There was often misfire when on and off the throttle repeatedly. While watching my STFT, I would notice how much fuel would just be going into the engine while knowing the fuel wouldnt even be igniting. New sparks made a pretty big difference as far as throttle response and smoothing daily driving.
Intake Filter - Cleaned it today for the first time - had the intake on for about 10k miles, no problems other than fuel trims, fixed it with ktuner - With a clean intake filter, it did make driving a bit smoother too. More air allowed to reach the engine compared to before. It honestly wasn't even visibly dirty, but it helped, that's all that matters.
Tires - Still on oem set of tires. One actually replaced due to one of the tires fully ripping apart driving too underinflated... They are still in pretty good shape, I just wish there was more grip. Roads here in Jersey are pretty awful too.
Weather Concerns - Turbo thrives in the cold!!! There is a huge difference with colder weather. When night time hits, I always love just doing so pulls. I never really have driven in the snow, but these oem tires suck. I can't drive in the tiniest bit of ice in my driveway.
