WI Failsafe Gauge INJ_PER

Can I use the Pwm signal from my infinity ECU that controls my WI pump as the INJ_PER input to the WI failsafe gauge? or does it have to be tapped into the wire going to my pump?

 

Thanks

Neil

It's intended to be connected

It's intended to be connected to the pump. We never tested it in any other configuration. You can try testing it to see if it works. I take it you're driving a solid state relay or something?

Yes I am driving a solid

Yes I am driving a solid state relay to run the pump... my reasoning for connecting to the pwm signal was that it will also give protection if the relay fails - I will try it and see.

OK Tested using the LS PWM

OK Tested using the LS PWM signal to the orange wire - it reads the signal, but it is reversed. So 0% signal shows 100% on the gauge and 100% shows Zero. So looks like I will have to tap into the pump wire..

The failsafe software is

The failsafe software is configurable to take either LS driven or HS driven signal. Check in Tools>Options. Also, the circuit is tested at power on to see state of the signal when in automatic mode so if you had the failsafe on before the Infinity, it would probably invert the duty.

Quick Update - the Gauge is

Quick Update - the Gauge is now working with the using the LS signal. It worked as soon as I left the wire connected and then cycled the power...

I must say I am very impressed with the ease of set up of the gauge - a great safety device!
