I have an Lc-1 wideband and guage. it is hooked up to my ms2 and TS reads about .5 leaner than the guage. so tuning with ve live is useless. I have tried grounding to the false firewall and the battery ground. it was better with the battery ground. on the false firewall it was almost one point leaner. should i ground to the ecu ground on the harness? I changed the setting in log works so both outputs are the same voltage range.

There are a number of different things you can do to make it work. You can try moving the ground around and finding the best spot, you can adjust the LC-1 voltage/afr transfer function, or you can adjust the AFR table in TunerStudio .5 point richer than it is now (which will make up for the .5 leaner reading in TS) and then VE Live will work just fine.

The "correct" place is the where the ECU gets its ground, although I would hardly call .5AFR of error useless for VE live. You can manually enter the calibration in TS instead of selecting the LC1 from a dropdown.
Have you connected to the LC1 serial data and verified that the gauge is correct?

I noticed today it was more than 2 point higher than what my innovate guage was reading. where does the ecu ground? 88 xr4ti? I was trolling the lc1 forum and it was mentioned to use a resistor inline with your wb input on the ecu side. i tried it and it did nothin..

Not sure where the ecu grounds in the XR, it's typically within a few inches of the ecu though.

I moved both my lc1 ground and ecu ground to my block....rear of the cylinder head and my readings are within .1
Edit....i argee with other poster...just get it as close as you can and adjust afr table to make up the difference.
