Default D15B Fuel Economy

Please share your fuel economy experiences with the D15B engine. I got 36 mpg highway -- no mods...is this about right? PRV induction bumped that to 50 mpg.

32mpg full interior on a good day (full sized spare) with a CEL that hasn't been fixed yet. I think it's okay, my friends hate me for it too

EDIT: Not the VTEC-E. Sorry, I keep forgetting about that.

What is PRV Induction? Sounds like a miracle drug.

chassis setup is more significant.

all VTEC-E d-series are about the same

Pretty sure it is, I'm jerry-rigged with a one-wire. I'm gonna try and BAR it, so I'm in the market for an SI Intake manifold, a four-wire O2, and a USDM P28 ECU. But, yeah, it threw that code since the day I swapped engines. lol, I'm lazy.
