I'm having trouble with my LC-1. If I do a free air calibration before I start it, it will work great for a while. Seems like after its been started a few times it looses the calibration. It reads all over the place and some times it will loose the analog voltage settings that I have stored in it. Innovate wants me to run my grounds to the engine block. I've gotten my power and grounds from the connector for the traction control switch. I would think that this ground would be good enough since it tied into the ground circuit of the car. The Blue and White are wires run separately to the ground wire. How are most of you guys grounding your LC-1? Thanks for the info.
