Default LC-1 screenshots

I hate to be a pain, but I'm having real problems getting me LC-1 to talk to my Megasquirt and NB AFR Gauge.

Can someone post screenshots of the configs for their outputs for talking to these?

I this AFR gauge:


The LC-1 shows good looking values, but on the Megasquirt they sit around 8-9 and never move. Do I need to do the resistor thing?

I'm about to pull up the carpet around the ECU to check the wiring too.

Does that AFR gauge show you the ratio in numbers or is it just the 3 tiers?

The output to the MS should be set for 0 volts at 7.35:1 and 5 volts at 22.05. For the output to the gauge, try setting it for 1 volt at 10:1 and 0 volts at 19:1 and you'll be in the ballpark.

IIRC, I have my outputting from 0-1v a scale of 18:1 - 10:1 (this is output the 20 LED gauges are scaled to be at with a NB gauge)



The output2 for the MS has a 0-5v 10-20:1 input. You need to make sure the MS is looking for a 5v signal not a 1v one....see basic settings, exhaust gas settings. change narrowband to wideband and the step size to 2.35v.
