Just wanted to give an update on the Bluetooth and CAN bus gauges...We now have a much smaller working "mule" development module.
This version shows real time engine coolant temperature, engine oil temperature, engine oil pressure and air/fuel ratio of bank 1.
The next version will have multiple screens to show more data. Items like differential oil temp*, real time tire pressures, automatic transmission fluid temperature, and current gear.
* The differential oil temp uses na engine coolant temperature sensor from a Nissan Sentra, with a custom adapter that we developed.
