I uploaded the Hondata supplied calibration for the Civic SI K20A3. Car runs farely well, but the log isn't the most appealing. Would like to know what steps I should take to keep everything in safe ranges. Also I have some very slight hesitation under 3K RPM when under part throttle.

I am very new with KPRO and tuning so any input would be greatly appreciated!

Attached is my current tune and also a 3rd gear pull from ~2K RPM.

No one has any insight/advice/input?

Hi,
check your fuel maps, car is runing lean. You should be in the 12,8-13,2 A/F area when WOT.

That hessitation you mentioned - that is very lean state - from 2700 to 3400, the rest is just quite lean. You should add around 15% fuel. Best would be to get it to tuner.
