I have a p06 ecu chipped with a crome basemap for turbo ls. I would like to know if I can swap out that chip for Hondata S300. My car runs but would like an easier way to get tuned w/o buying a new ecu.

 

The s300 system uses totally different hardware to mount to the ecu.
You will need to de-solder the current 28 pin socket in order to install the s300 male pins.

The eCtune and Neptune RTP systems use a board which uses a coexisting 28 pin socket.
