Vehicle: 2018 Civic Si Coupe

Total tuned time: 6 months

Total tuned mileage: 3,000 miles

Tuning device(s) used: Ktuner V1.2

Tunes used: TSP Stage 1 for Si

Fuel used: Chevron and Shell 92 (highest octane offered in Oregon)

Additional engine mods: 27Won CAI, ACT Organic clutch kit, 27Won RMM, Ruthenium HX plugs.

Problems/issues: Clutch slipped the first day I had the tune flashed. I was on the freeway going ~70 and I mashed it in 4th gear on a 90 degree, banked interchange ramp.

After I tuned, I notice I began to have an oil leak that appears to be from the timing chain inspection cover. I doubt it's related to the tune, but it coincidentally started after.

Many, many clutch master cylinder issues that are documented in other threads I've made. Still working that one out, but it's mostly related to the clutch swap instead of the tune.

Driving style: I rail on it constantly. I rarely hit it hard from a dig but we have many, many beautiful and curvy back highways here I hit up all the time. I'm just waiting for my 4th gear to blow up since that's where I spend most of my time.

Tuning experience notes: This was my first experience tuning a car. The cost of entry is very, very low on this platform, especially for Ktuner, for the entire ecosystem and level of community and vendor support you receive.

TSP Stage 1 for Si really, really unlocks the great potential these engines have. At first I was very cautious, watching fuel trims and knock control religiously. I still have tunerview setup to automatically launch on the head unit every ignition cycle so I can watch the readouts for peace of mind. But it's been long enough without a hiccup with regards to the engine I feel comfortable driving the way I want to instead of constantly acting as if I'm driving on glass and watching knock control.

One major downside I've noticed about the V1.2 is the tunerview app for the head unit has many, many bugs. It constantly disconnects and stops reading values from the Ktuner. It frequently will not connect on app launch. And all the time it gets stuck in a loop where it constantly dims the screen and says it's connecting to the ktuner when it's already connected and reading out values. I wish there was a better solution for this, but outside of getting a V2 which has its own display or using a phone or tablet to run it independently of the head unit, I feel there is no real solution.

Additionally, I am very bummed that tunerview won't show knock count. The ktuner software shows it, the V2 shows it. Why can't the 1.2 show it in tunerview?

I know I'm in minority here but I had no issues whatsoever when I had the Hondata app. Tunerview looks better and is more detailed, but for me, it's seriously buggy in terms of it getting and holding a Bluetooth connection. Thankfully, I have a V2 and I just use that instead.

Try to set, in tunerview settings, autoconnect delay to 1000.

It is the same app as the phone/tablet app, but without things like video overlay etc. The connectivity issues are generally with the head unit hardware, though we never had any issues with our Si.

Knock count is not what to keep an eye on for this platform to signify health. Knock control is!

Vehicle: 2019 Civic Hatchback CVT

Total tuned time: 2 months+

Total tune mileage: 600 miles+

Tuning device: Hondata Flashpro

Tunes used: Basemap +3psi Hondata tune with modified torque limit table, TSP Stage 1 (Current)

Fuel used: 93 Octane

Additional engine mods: None today but plan to use aftermarket replacement filter, freeflow DP, and upgrade IC.

Problems/issues: Concern on fuel trim. The car running 5%-15% too rich. Cannot adjust the AFM because the calibration is locked. I'm thinking about asking TSP team to unlock the calibration for me to adjust the AFM or have TSP team adjusting the AFM for me to make the car running less rich.

Driving style: Stop-and-go traffic 95% of the time with occasional morning run (05:30 AM) weekdays and 06:00 AM in the weekend.

Tuning experience notes: This is my 3rd car I have tuned but this is my first experience with canned tune. I used professional tuner service in the past and had my car tuned on rolling dyno but Civic is an exception and I am happy that I make the right decision to purchase TSP Stage 1 tune. I haven't dyno the car but do plan to go to dyno to measure the power and check the actual boost.
Update:

Total tuned time:
5 months

Total tune mileage: 2,285 miles

Tuning device: Hondata Flashpro

Tunes used: Basemap +3psi Hondata tune with modified torque limit table, TSP Stage 1, Self-made 19 PSI (Current)

Fuel used
: 98 RON (93 Octane?)

Additional engine mods: None today but plan to use aftermarket replacement filter, freeflow DP, and upgrade intercooler.

Problems/issues: I'm very concern with the fact many of tuned Civic in my country experience damaged conrod with boost higher than 21 PSI. I know this might sounded funny for most of you here but this is fact in my country. I found out TSP Stage 1 peak boost at about 23 PSI with occasional brief over-boost to 26 PSI. I also found out torque limit was set higher than 250 nm from 3,500 RPM and up. Due to these concerns, I decided to tune the engine myself.

Driving style: Stop-and-go traffic 95% of the time with occasional morning run (05:30 AM) weekdays and 06:00 AM in the weekend.

Tuning experience notes: I love my 19 PSI custom tune. It's not as fast as TSP Stage-1 but it is fun in its own way. Car feels like a bit quicker than stock below 2,500 RPM but past 2,750 RPM, the car picks up speed nicely. "Torque limit" is within Hondata spec of 250 nm maximum torque limit. I also tune the AFM so my STFT looks much decent (betwen -10% and 0) than any canned tune including Hondata basemap (between -15% and -4%). If I ever to perfect the tune with the help of professional tuner, I will definitely use my custom 19 PSI tune as the base and only ask to perfect the AFM, as well as improve fuel and ignition tuning, without changing boost parameters.

I've tried just about any configuration of those settings you can imagine to no avail. Also deleting and reinstalling the app, resetting Bluetooth on the head unit, doing a head unit reset, battery cable pull, etc.

It is the same app as the phone/tablet app, but without things like video overlay etc. The connectivity issues are generally with the head unit hardware, though we never had any issues with our Si.

Knock count is not what to keep an eye on for this platform to signify health. Knock control is!
It was my understanding that knock count can be used in conjunction with knock control to determine if spikes in knock control are preventative or reactive.

Although I suppose I should expect knock control to spike much higher than 0.75-0.80 if there is a real problem, no?

*UPDATE* 4th time
ORIGINALLY POSTED ON 04/09/2020

Vehicle:
2020 civic Si.

Total Tuned Time: 2 months. (First tuned on 04/01/2020)

Total Tuned Mileage: *
*Update* 05/28/2020 Odometer reads 16,050 *Update 05/14th/2020* Odometer reads roughly 14,800k miles.

Total tuned miles by date.
05/28/2020
3250 miles.
05/14/2020
2,000 miles.
05/01/2020
1,500 miles.
04/01/2020
400 miles.

*Was at 400 miles when I first posted the miles tuned. *

Tuning Device Used: KTuner V2.

Tunes & Settings Used: *Update 05/14/2020* [PRIMARY & Current TSP Stage 1 street]
[Previous Tune Starter ~ Base/23.5] (Throttle Response 1. 2-STEP SETUP @ 3950k-4000k-No Rev hang)

Fuel Used: 93 Only.

Additional Engine Mods: PRL silicone hose / K&N panel replacement/drop in filter.

Problems/Issues:
*Update* 05/28/2020 (Same rare issue)Jerky throttle is more related to a limp throttle. Associated with large some knock counts maybe missfire?
*Update 05/14/2020* TSP stage 1 - Rare issue, but it seems to give me some jerky thottle respones every so often. Also, im running super rich. After 2-3 70mph pulls, my exhaust smells like fireworks. Elevation is at 544. Ive noticed that I get a lot more knock counts(like some times in 10 minutes 30+),and an occasional rise in knock control. Usually to 0.52-0.54.
I will start looking for better fuel in town.

Vehicle: 2017 Civic Si Coupe

Current Mileage: 50,100

Total tuned time: 5 Months

Total tuned mileage:
~10,000 miles

Tuning device(s) used: KTuner V2

Tunes used: TSP Stage 1

Fuel Used: U.S. 93 Octane usually Speedway gas station bc its the closest near my place

Additional engine mods: PRL "Street" Cold Air Intake, PRL Downpipe, MAPerformance Race Exhaust, 27Won RMM

Problems/issues:
smoke bellowing out the exhaust after downpipe install at 45,000 miles but I changed my oil bc it was overfilled and put the correct amount and got the same TSP stage 1 tune but changed the idle to 1100. I don't know what ACTUALLY fixed the problem bc I did both almost at the same time but the problem seems fixed, 5,000 miles later and no hiccups everything seems to be in check.

Driving style: Majority of the time cruising 5 above the speed limit, 1-3 WOT a week if that and some spirited driving along the way.
