Is it possible to do some rough VE tuning without a wideband? The VE tutorials I've read all require a wideband. I'm trying to dial in my tune at idle just to get this thing to pass smog. Right now it's putting out 36% too much HC at idle, but is 92% under the HC limit at 2500 RPM. It is also misfiring slightly at idle which is probably the issue. I'll get a P0300 after a couple minutes of idling. The misfires are spread out evenly across the cylinders. The tune is stock at the moment.
