Question about setting up injector fuel trim.

Alright here's the question. I have a 1995 honda Accord, H22a engine swap, and a P28 ecu. When asked for the stock injector size. Should you put stock injector sizing for the Accord, JDM Prelude, or Civic SI. I would assume Civic SI because that's what ecu it is. And I have installed 550cc RC injectors so New injector size would be 550 of course. In the S300 software it says it will automatically adjust for the fuel rating of the injector. How does it compensate?

Also 1 more quick question. Just wondering if anyone had any problems with stereo noise after S300 installation. I have and if so does anyone know how to correct. It may just be coincidence though.

Thanks.

The calculations are made use the stock injector size - which applies to the engine, not the ECU. H22A are around 310cc, so use 310 and 550.
