Review on 📊 Advanced PE Wideband O2 Bluetooth Kit - Air Fuel Ratio for iOS and Android Optimization by Jeff Jackson

I use this on my 1974 Triumph Spitfire and it's great as it doesn't require a dash and can be installed discreetly almost anywhere. The accompanying phone app is good but not great, probably the only thing I can get out of the product at the moment. For some reason I can't get the device to automatically connect to the app, which is a bit annoying. The app isn't very good at switching between other apps either, and loses connection when it's done. However, important aspects such as measurement and history are well presented and appear accurate.
