Do I need two EFIE circuits

[wantfreeenergy]

I have the 2 o2 sensors before the cat conveters and I was wondering if I need an EFIE on both sensors?

With only the one EFIE on the one sensor my vehicle is running smoother and actually goes when I push on the narrow pedal. It is typically a LAZY dog, not no more though.

Does it need two EFIE's?

If you have two O2 sensors you sould look at getting a efie which is designed for multiple sensors. This omho would be better than two seperate efie's as it's all in one unit and you don't have to tune two of them.

Thanks for the reply I'm gonna build and install a second one since I already have one on there.

Good stuff to know. Does anyone have a schematic for vehicles with two o2 sensors. I'm gonna build these for my family so we can all cut our impact. OR is it simply just two of those LM3914 curcuits on one pcb board?
