- CAN Bus output of Lambda or %O2
- Smart Heatup; RPM Triggered Heating of the oxygen sensor for MS3 ECU.
- Smart Heatup; Temperature Triggered Heating, Spartan 3 will wait for the Oxygen sensor to be heated to 350C by engine exhaust gas before heating up the sensor
- Does not require Free Air Calibration but FAC is available. Recommended only for clone LSU 4.9 sensors
- Compatible with Torque OBD for Android to display AFR
- Onboard FTDI based serial-USB converter
- ARM Cortex M4

Used both the Spartan 1 & 2 with good consistent results unlike my previous Innovate LM-2 WBC, both do exactly as intended although I do prefer the neatness of the Spartan 2 over the 1, previously never heard of 14point7 until I read some promising reviews online, glad I did.

very simple clean looking setup if i didnt already know its a wideband id have never guessed it was anything more than an O2 sensor with a long wire harness
installation was pretty easy its literally just running a wire !!!! also recommend you purchase the gauge to go with this as it looks great

seller communication was a little slow but he was always helpful and answered questions even help sort out a little mixup with no hassle
item arrived sensor seems to have been a new but pretested before sent out to prevent errors i do appreciate the quality control there
item was much smaller than i anticipated and seems to be easier to hide away its basically a long cable u can cut to length
added bonus was that it emulates narrowband signal for stock computer so u can have wideband without putting a bunch of holes in ur system :)
