The Tuned CivicX Experience & Reliability Thread (for all models)

[gtman]

A couple of notes.

Added a new stat for most used fuel. So far 93 octane, by far.

I've noticed a few recent surveys are leaving out the tuning experience notes. If possible, make sure you include that because it's really helpful. Thanks.

Oh, Hi local person! *waves*

My family has been going to Sound innovations since I can remember. Waiting for the spring to install new intercooler then I'll probably be headed your way.

 

[Veradian]

Vehicle: 2018 Civic Si Sedan

Total tuned time: 10 months

Total tuned mileage: 15,000+ miles

Tuning device(s) used: KTuner V2

Tunes used: TSP Stage 1 for ~5k miles; Current: TSP Stage 2/FlexFuel

Fuel used: Speedway 93 and E85 (combined, never exceeding E40) and Kroger 93

Additional engine mods: PRL Catless downpipe, FX350 w/ Aluminum SMF, 27Won RMM

Problems/issues: One spark plug failed recently, engine, trans, etc. noises, clutch slipping with TSP Stage 1

Driving style: Quicker acceleration than most but nothing crazy, an occasional 3rd gear pull. Occasional spirited driving with friends, but generally pretty normal.

Tuning experience notes: First car I've modified/tuned. Started as a noob afraid of changing my oil. My mechanic friends helped me through my modding journey to the point where I'm comfortable working on my car on my own. I haven't the slightest idea how to write a custom tune, but I do my best to understand how each part is going to effect my engine. Recently started monitoring more "advanced" aspects of my engine - STFT, LTFT, AFR, etc.
