I installed this unit under my hot rod. Originally showing 14.8 to 14.9 did a drastic jet change, but no change in the reading. Also read the same at wide open throttle, idle, and even when the engine isn’t running then I unplugged the o2 sensor and still reading 14.8. not sure what I’m doing wrong but it’s easy insulation. Haven’t yet found customer tech support.Just goes to show you. Don’t buy Chinese garbage.

Complete kit, easy install, plenty of wire, A+. Helped me tune my car so it would pass California smog. Money well spent.

For the price you can’t complain or compare it to units 2-4 times it price. Doesn’t seem to recover in real time after a lean reading. Also; It does not have a data logging output but I’m sure you could open it up and create an output with some type of isolation, I will probably try either an optic isolater or transistor based to avoid damaging the unit. *not advised and will void warranty
