Smart Fuel Mixture Display for Fuel injected Cars

[NP99]

Another gadget for the patrol..........This new ‘smart’ version has a few additional touches such as auto dimming for night driving, emergency lean-out alarm, and better circuit protection. Another great feature is the ‘advance’ display, which operates when the ECU is operating in closed loop. Closed loop means that the air/fuel ratio is optimum for fuel economy and emission performance. Kit supplied with PCB and all electronic components.
* Car must be fitted with air flow and EGO sensors (standard on all EFI systems) for full functionality.

Actually they only work in closed loop because they connect to your narrowband sensor.

I built their 1st version some time back then installed a wideband sensor with a correct AFR gauge.
I'm sure I still have it lying around somewhere if you want it..

Thanks John. When I fix that exhaust I'll take you up on it. I think the exhaust job is getting closer to the top of the job pile

Shane, do you have an Ecutalk readout? They are by far the best investment. You can see what your O2 sensor is doing (within its narrowband range) along with a whole lot of other good info like battery, engine temp, injector duty, timing, etc..

No mate, I think I need to look into it. Cheers.
