I'm just in the middle of sorting out a new LC1 instalation - and I cant get my head around programming it
I have done the free-air callibration , and as far as I can see set it to 0 to 5 volts , but the gauge dosnt read right - it sits at a reading of 8 , without moving when the throttle is touched .
Any ideas what I'm doing wrong ?

Free air calibration is all I did on mine then it worked fine.

I know I'm stating the blooming obvious here but you do have to do that bit with the sensor out of the exhaust! I guess if you don't it could put it quite out of whack.

What are you using as the gauge? One of Innovates like an XD-16 or something else?

Sorry to hijack this thread but what lambda value did you get when you did your free air calibration? I seem to have AFR of about 22

I have an LC1 with a wideband sensor and I think the voltage range is 0 - 7V so I have a voltage of above 5 Volts which in the lookup table in my DTA ecu is in excess of Lambda 1.5...

Surely the 5v is the reference voltage its supposed to get from the controller?

Are you following the instructions? It's 3 years since I did it but IIRC it was as straight forward as following the text. Don't forget they have two outputs too, make sure you pick the right one.

also the LC-1 has two outputs

first is for a bog standard afr guage (simulated narrow band signal) second is to the ecu or to a proper wideband afr guage and will give the 0-5v range
for this to show correctly in something like megatune i had to start a new project and telling it that the LC-1 was fitted until it displayed the readings correctly,
