I have for sale one PLX R500 Wideband O2 system.

Included:
R500 controller
O2 sensor
Firmware programmer
Owners manual (printed)
Logging software on disc

This controller, can display the AFR, along with other inputs, such as MAP (Boost), EGT (K-type thermal couple needed), Engine speed, Vehicle speed, knock sensor and other 0 to 5V sensors (TPS, second MAP, etc). There is a built in memory that stores logging sessions, and then you can dump the log to your PC.

There is also a warning light that can be set up to come on triggered by one or 2 variables, such as AFR > 14 and boost > 4 PSI. It can also be set up as a single variable such as RPM > 6000, or whatever else you can think of, that is connected.



Asking $250 + shipping
