    i've been using a dashhawk in an effort to gather some logs bone stock before i start making some mods. it seems that these trucks run pretty lean, especially during cruise. the commanded a/f and what the sensor is reading is about stoich when cruising. i only see it richen up when i let off in between shifts (manual), and most runs when i get on it it'll go into the 12s. but i had one run when i was on it and the a/f ratio didn't really dip at all! very strange.

    so i'm curious if anyone else has logged anything using the OE widebands.
