Hondata

hi everyone.

i need help about calibration.
i have 09 civic si stock complete bolt on turbo kit from greddy. hondata 4bar map and 550cc bosch injector etc...
so i would like to know which calibration to upload ? racing calibration or stock calibration for it.
does my civic si came with stock wideband? or do i need after market one to hook on to tune?

thank you very much

spunker? which calibration u would recommended for me to load.

You need to start with a Civic-Si-RBB calibration - it doesn't matter which one, as any are going to require tuning for the injectors and turbo. Enable the speed/density fuel tables.

The 09 Si has a wideband o2 sensor.
