Does anyone have or know where I can find a JDM B18C Type R basemap for a hondata s300?
I tried uploading the us 01 type R basemap, but it seems to be burning a lot of gas, also from what i read the compression ratio is different in a JDM B18C type R.

I just don't want to get a tune until I do my turbo and fuel set up.

 

It is, but not enough to matter that much. If you are concerned, pull 1° or 2° of timing. Most of the Hondata basemaps suck, but you can adjust your low cam fuel without too much worries if you have a wideband O2.
