OK, so I'm getting ready to install the A'Pexi Turbo Timer w/AF Display. Does anyone have experience with the accuracy of this particular air/fuel display relative to other narrowband options? Did you tap in at the sensor or at the ECU? My thought with this unit was to kill 2 birds with one stone for initial (mild) tuning purposes but the display is pointless if the thing is way off for some reason.
Peace...(hippy)
