Motor is quiet at cruise with a lope at idle. All you hear is the exhaust note and its a mellow purr. Not harsh or loud. No drone in the cabin even at 1600rpm or so. Tuning is soooo much easier using the Ostrich and =Jeff='s VeTuner. You can have a new set of VE tables calc'd in about 3 min and then ready to download.
Next is installing the WB O2.

Tell me about the VE tuner function...does it make a base map off of STFT values or does it use a strategy to tune each cell based on a target air/fuel ratio using a wideband or even the O2 sensor?
