lm1 Reading Questions

[MoTruck]

I have a couple of questions that hopefully someone can help me sort out. I have an LM1 hooked up to log with Efilive. I added an additional bung right next to the front stock 02 sensor. When I log in closed loop, the lm1 readout reads approximately 14.5. The readout in Efilive is slightly higher. I set the extra voltage out on the LM1 to a constant 2.0 volts. The voltmeter I have reads the output at the orange connector as 1.98 volts. What do I need to do, to ensure that Efilive is recording an accurate reading? Thanks, Motruck

Do you have a V1 or V2?

I have a V1. I just went and checked it out again. It hovers in the 14.4-14.5 range at most engine speeds in closed loop on the LM1 screen. However, the reading in Efilive is around 14.0. Thanks.
