NO AFR reading from Megasquirt...

Post by JamDoc »

I am running the Megasquirt v2.2 with spark control, with a LC-1 wideband setup. I noticed today that when I run Megatune the AFR gauge is not reading at all: it is 'pinked out' (i.e. it looks like when the system is off), whereas all the others are active and reading normally.

I have the lamda settings in the configurator set to LC-1, and when I tested the yellow output wire from the LC-1 with a voltmeter it shows a 1.25V signal at idle, so that seems to be ok (i.e. the sensor is working and sending a signal).

Any ideas what this issue could be?
