Ive just taken delivery of what i see as one of the most complete and usefull wideband AFR monitoring kits available on the market today for use In car. I will be testing it back to back with my £6K+ industry standard test unit to see how it compares and will have a magazine in tow to record the results later on this week

It features:
Bosch LSU4 wideband sensor
52mm backlit analogue Gauge so will fit in all standard gauge pods
External control unit for ease of installation.
10mins Data Aquisition at 10samples per second (Datalogging)
Accurate from 10:1 - 18:1 AFR

Main usefull feature IMO
Rpm and TPS are monitored and used to control an external item.

Example:
You could set it so that if;
Rpm = >4000
TPS = >60%
AFR = >12:1
Then it earths a wire to Activate NOS.

Obviously in the above example, the NOS would be disabled should the AFR be below 12:1
The wiring possibilities are endless You could perhaps have something that earths the coil if these conditions are not met, thus building your own AFR dependant RPM limiter to save a meltdown if the tw@ using your car ignores the warning light

It also features extra analogue inputs that can be displayed on the PC software for datalogging. Common uses of the inputs would be things like boost / TPS / RPM / or perhaps fuel pressure.

Warning lights can alos be configured for various inputs, most usefully though is the fact they can be configured against RPM and AFR so you could ask it to warn you if AFR gets lean at WOT

Heres a couple of pics:
