AFR gauge
I just bought an AFG gauge that hooks to a narrowband o2 sensor.

I have 2 upstream o2 sensors w/dual EFIE and 2 downstream o2 sensors

My question is: should I connect the AFR sensor up to one of the downstream sensors? I believe the EFIE voltage would give me a false reading on the AFR if I hooked it to the upstrean sensors.

Thanks JP

RE: AFR gauge
I'd connect it before one of the EFIE's, wire closest to the sensor.

RE: AFR gauge
I'll test it out and let you know what works. I'm sure the EFIE would throw off the reading, but I will try every possible way to hook it up.
