So I bought an LM2 wideband, but when I select the lm2 transform and log data it doesnt give the same reading as the handheld unit. I've went into the LM programmer software and check the output voltage vs lambda/afr settings and they are correct. If the handheld reads 14.0 the transform reads 15.5 in hpt. So I created a math with the reading -1.5 and it matched the handheld. What is the correct way to fix this. Thanks
