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.

 

did u calibrate teh sensor?
what wire do u have hooked up to the MS?

 

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.
