I have LM-1 W/B, I connect it to V2 via the analog output. The ground wire (naked one) is connected to the -ve end of AD1 and the white line is connected to the +ve end of AD1. There is a difference between the reading on the LCD of the W/B and the reading through efilive scan tool. The difference is 2.0 to 2.5.
Can u tell me if there is a way to have both of them matching each other??
Which one is more accurate?
