Common Features of Spartan 3 and Spartan 3 Lite:

  • 10ms Response Time
  • ARM Cortex M4
  • 0.1% tolerance components for all components that affect accuracy
  • 4 layer Printed Circuit Board
  • Separate grounds and power connections for LSU Heater and electronics for improved noise performance and improved voltage protection
  • 1x High Perf Linear voltage output, 12-bit 8MSPS DAC with 0.1% tolerance voltage reference, that together with the separated grounds makes this linear output very accurate with very low noise. 
  • 1x Stand Perf programmable linear voltage output driven by an RC filtered 8-bit PWM.
  • Supports both the Bosch LSU 4.9 and Bosch LSU ADV sensor. Spartan 3/lite with LSU ADV will prove a 20x increase in lambda resolution versus Spartan 3/lite with LSU 4.9.

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 :)
