OK, I'm lazy but how does the new HPtuners and the lm-1 hook up together? What output on the LM-1 goes on which of the unlabeled HPtuners inputs MVPI interface?

I'm about to go to bed, but there's lots of discussion in the help section of HPTuners forums that describes ways to optimize the wideband readings... but the first link shows the pinouts

OK, so the LM-1 output goes to any of the top 4 inputs...single wire hook-up?

yup, then hookup a ground reference to the first ground (don't use it as the LM1 ground, just wherever you ground your LM1 use that same reference point)

So you need to run a seperate ground wire from the LM1 power to the EIO? Would you just splice into the power cable going to the LM1 and pull a ground wire off to the EIO?

There has always been about a .4 difference between what my LM-1 is reading as opposed to what's showing up on my laptop. Perhaps I have a ground issue?? I just hooked up the ground from the LM-1 to the ground on the EIO. So it is advised to find a grounding point in the vehicle and run a jumper to that point from the EIO and LM-1?

I keep getting info for the LC-1. Is the LM-1 similar in wiring and use? I'm not familiar with the LC-1.

The LM-1 has a single analog output jack and doesn't have the block wiring labeled the way it is in the HPtuners instructions for the LC-1.

Thanks for the patience with my questions.
