Hi guys,
As some may know from our Facebook page, we have been working on integrating a wideband o2 sensor to the OpenFlash Tablet. And it works great. Right now we are just trying to source some connectors so that it can be 100% plug and play. Currently we are just replacing the secondary o2 sensor with a Bosch Wideband o2 sensor (LSU4.2). It plugs into a wideband controller. And that will hopefully plug right into the secondary o2 sensor connector once we source the needed bits. We have added a "Wideband AFR" channel to the OFT logging that converts the analog output of the wideband controller to AFR. As you can see from the following graph, the factory AFR and Wideband AFR reads very similarly until exhaust temps begin to rise (high high RPM WOT). At which point the factory o2 sensor reads leaner than they really are (which is certainly on the safe side of things):

This secondary o2 bung location is ideal for those with cat-less headers (like the OFH) since it is recommending that no cat be upstream of the wideband sensor. For those with catted headers, it is recommended to install the WB sensor just upstream of the cat using the supplied weld-in bung.
I should have word on the plug-n-play connectors later this week. At which time we will be able to give release date estimates and prices. But expect it to cost around $200 for the OFT wideband kit. In the meantime we will be fine tuning the calibration to ensure best possible accuracy
