serial lc-1 logging

[B18B1LS1]

How close should my logged lambda be to what my Dyno Tune gauge is displaying? I seem to be logging .2 AFR richer than what my gauge reads. Not a huge deal, but it would be nice if they were closer.
Also, is there some way to get my gauge to display in lambda, I'm not a fan of AFR anymore.

Thanks!

Where are the sensors located...?


Which gauge do you have...?

[B18B1LS1]

O2 sensor is about 24" off the turbo. The gauge is the round digital Dyno Tune Air/Fuel, like this, https://www.dynotunenitrous.com/store/scripts/prodView.asp?idproduct=388

Do you have the user manual pdf's for the LC-1 and the gauge...?

[B18B1LS1]

I don't believe so. I've had these over 10 years I bet. You think I have the voltage offsets wrong for the gauge maybe?

Does the gauge run from on eof the LC-1's analog output's...?

If so, then you can use the LC-Programmer software (from Innovate) to tweak analog output a little to make the gauge match.

Yes it's on 1 of the analog outputs. So what I'm logging is the most accurate because its coming straight from the serial connection on the LC-1. And the gauge is just interpreting the values programmed into it. Bring the gauge inline and all is well. Thanks joecar, seems so simple after typing it out!
