14Point7 Spartan 2 Wideband O2 Lambda Controller with Genuine LSU 4.9 Sensor

I had no idea what was going on with my carb.. tried a China narrow band sensor interfaced with an Arduino..then tried a US sensor it didn't help. readings were all over the place... purchased the 14point7 interfaced it to a 4 digit led display via arduino using its linear 0 - 5 vdc output... carb turned out to be very rich .. The problem was solved.. now I have 13.9 at idle and 14.7 at all cruising speeds (30 to 80 MPH) runs rich under WOT , but who cares.. saved my carb . I got this by adding adjustable fuel restrictors and air bleed jets to my Holley's idle circuit.

Pros: Easy to install. Quality materials. Works great.Cons: Controller isn't water proof and the interface being close to the sensor may affect longevity.

A must if your run a stand alone ecu works as it should

Worked great!! Instructions were very well detailed and installed in my miata with a speeduion ecu. Look at 14point7 web site for maximum accuracy to tuner studios.

Works perfect and is accurate. Installed on boosted ls1 controlled by Ms3pro. Bought it to replace a failed 2 week old Lc2.

Awesome wideband controller, newest Bosch sensor, easy to wire in, works great with my MegaSquirt 3 ECU!

Good product. Works as expected and is a valuable asset to my data logging.

Straightforward and simple installation with Megasquirt MS3X.
