Hondata

hello i have a hondata ecu s300 from another integra with a b18c engine as mine, both cars are turbo applications. how do i find the info pertaining to the settings of this ecu before i am able to use it in my car? i don't know what type of injectors he used and what were his other tune settings. can anyone help with this?

You can try going to Online, and Download, but this is not recommended. Since tis is a different vehicle, you probably should just go to the new Calibration button and start with a fresh base map and tune it accordingly.

Both cars are the same,the difference is the injecter size.is there a way to just change just that setting?

You can try but you will aslo need a wideband to get the fueling correct. Injectors have different flow rates at different pressures and voltages. This is not something you can compensate easily for by changing one parameter.
