Nobody knows an answer?
Or maybe I shouldn't worry about it and it's good?
I'm little confused because the sensor is keeping nice constant heat voltage and Nernst voltage is 0.45.
If it matters the sensor is from BMW E46 320d Euro 4 version, I bought 2 pieces in case 1 was damaged.

Re: Open Source LSU4.9 Wideband Controller
I tested it with 2 multimeters, the difference between them is about 0.03mA, which resistor could make this kind of problem when I'm measuring the pump current directly?

Re: Open Source LSU4.9 Wideband Controller
Hello. I'm following the project for a while and I finally assembled HellFire's design but there is one thing that startles me - everything is working great, heater PID and Nernst PID but I think the pump current is too low, when I connect multimeter in series with red wire of LSU4.9 I see about 2.3...
