Civic Si Air Flow Sensor

Since we were talking about it last night... I can't find the CRSX threads about the turbo Si. I found this though.

That's nice because the RSX runs lean with I/RH/E; I don't really want to try running that in the summer.

Just to compare what the Si does... This is stock ECU vs reflash ECU, of course the reflash picks up mid-range, but look at the peak hp. Not much of a gain at all. Most of the mid-range pick-up comes from moving the VTEC engagement.

Sure would be nice if the RSX had the same ECU/air flow sensor.
