Hello Martin,
Thanks for reply.
At this time both Lambda Vs pins are already occupied for lambda meter input for both bank.
I'm setting ECU up for engine bench and I would add another input signal to force fuel cut.
I need to cut fuel very quick, even before overrun fuel cut work.
Also sometimes I need to cut fuel without throttle closed.
I would input the signal from bench control panel (5V or 12V or GND)
At this time vacant input pins are:
DIG 3,4
Lambda pump 1,2
AT 5,6
My idea was setting -100% in Fuel Comp2 map when fuel cut signal voltage comes on.
AT has 5V pullup with 1k ohm..
So, if I make AT pin connect to a relay to GND,
grounded=0V
open=5V?
if so, this should be good enough to work with...
The input signal should be OK with digital (on or off), so connecting to Digital input might also be possible.
However I have no idea how I can set it up in digital input setup and axis setup of comp2.
When I use digital input, function should be... monitor?
How I can specify Hi/Lo in axis setup?
