serial lc1 calibration? Please Help

[EVI]

I recently upgraded to a serial cable from my lc1 to my v2. I finally figured out how to get it to read but it seems it is reading way too lean. If I do auto ve, the numbers say I need to add like 32% more fuel. When I do the ls1 camaro that I am working on runs way too fat. When I get it to run decent the afr is like 19:1. Do I need to calibrate my lc1? What do I need to do to get the afr to read more accurately?

Recalibrate it for free air and check the fuel setting.
Make sure it is set for gasoline not set to custom.

Ok, I'll try that tommorrow
Thanks
I'll let you know later. If it works.

It's the default settings that came with the lc1. I've never changed them or even looked at them because it don't have a serial port on my computer. It has always worked with the analog set up. Would something be different now? I am still going to do a hearter cal and a free air cal. I may have accidentally screwed that up when I was trying to get things right with the serial cable set up.

I' had mine jump to custom for no reason,
You can use a serial to USB converter to connect to your laptop.

Ok I will double check it. My friend has a converter I can borrow.
Thanks again

I borrowed my friend's converter tonight. You were right, for some reason the cal on my lc1 changed to some custom setting. I switched it back to 14.7 afr and everything seems to be back working like it's supposed to.

I just started using the forum for answers because I couldn't get help anywhere else. You guys are great! Thanks for replying and all the help.

The LC- is notorious for switching settings.
FWIW
I have not had this happen since I upgraded my alternator.
It might be caused by inconsistent or spiking/dropping voltage.

The car I was working on had the battery cable loose and the starter would intermittently not engage. That would definetly cause voltage spikes.
