We tested my lc1 xd1 against the lm1 and mine was reading .4 richer.... Now my sensor is in the test pipe. and the other was a sniffer in the tailpipe would it make that big of a difference? Wondering if anyone else has tested theres to see

 

Yes it will make the difference between the two locations of the sensor. I would rather go on the sensor in the test pipe

 

Yeah I agree. I just didnt think that it would make it read .4 difference thats crazyness anyhow thanks
