13' Civic Si. Running Reflash. Tune help.
Posted: Wed Oct 07, 2026 4:41 pm
Received my flash pro today and went ahead and used the US CIVIC SI 2012-2014, Hondata Reflash base calibration from the drop down menu. The "first data log" is from the base tune. The other data log is also from the base tune. I decided to tweak the base tune based off a few parameter changes. Wanted to have someone review that "edited reflash" base tune because i am wanting to use it as a starting point to begin tuning my vehicle. From the data logs it looks that my ecu is pulling too much timing. I will be pulling data logs during the week. Currently only running a cat delete 3" exhaust and a 3" cat back exhaust. Data logs are not from the calibration provided but were captured with the base tune stated at the begging of the post.
