Hello everyone, this is my first post. I have a 2017 Honda Civic Si Coupe, with 50k miles. On my Ktuner V2, it’ve noticed my Short term fuel trims(STFT) usually range between -16% to 4%. My Long Term Fuel trims (LTFT) currently sitting at -14% to -10%. I am in college right now, and my driving habits consist of short trips to the gym, Walmart or doordashing (a lot of idling). Whenever I commute home (2.5 hr drive), I can ‘manipulate’ my short trim to make my long term fuel trim reach 0% or -1%. I cleaned my air filter last night and my fuel trims look about the same after going on a drive. I’ve read 27Won’s article on air fuel ratios, but any one have advice on what it could be? Maybe new spark plugs, because I’m running 21-24psi whenever I beat on it. New fuel injectors? Should I drive with rev hang, or keep it off?
Current modifications:
- Ktuner V2
- TSP Stage 1+
- Cobra Cold Air Intake (Street MAF)
- Type R shifter assembly
