Nice to see another HX swapped EK hatchback. Mine uses a VX trans, but same HX engine ecu, etc. your goal of 50 MPG should be pretty easy to hit. Just need to figure out how to drive that new engine of yours!
I still have issues getting in lean burn whatever I want at low RPMs. It is really picky at the 1900 rpm level. I have figured out how to use the low speed lean burn, but if I hit traffic and kick out, it will not go back in at the lower rpm. At 2400-2500 it seems perfectly fine though. Still troubleshooting it.
Below is the link to my build thread.
