09 Civic Si Base Calibration
Posted: Mon Oct 13, 2025 8:15 pm
Hey everyone,
Reaching out to see if I can get some help with a base calibration on my civic. Car was tuned and modified prior to me purchasing it but I’ve made a lot of modifications to the car since then and I’m unsure what to change in Hondata to help it run better. I am getting a slight misfire on idil and rev down at around 2500/3000 rpms. I’m not trying to push power, just looking for a safe base calibration to have the car driving cleaner. I do live in Canada and will most likely have to drive the car through the winter.
Build list:
Skunk2 72mm throttle body
Skunk2 Intake manifold
Skunk2 longtube headers
Skunk2 catback exhaust
Takeda stage 2 short ram intake
Rdx 410cc injectors
Stage 2 1750lb load clutch
6 puck ceramic disc flywheel
Ktuned Slave cylinder
Ktuned master cylinder
Deatschwerks 65c 265lph fuel pump
Thank you in advance for any help and advice!
