REVELTRONICS

Hello,

i have a problem with the logging of the LPG status.

The tank valve gets activated with +12 volts, after a few seconds it gets reduced to 4,4 Volts.
The ut comp switches back to gasoline.

Is there a way to change the switch voltage ?

In the manual "(low state 0V - petrol, high state 3V and more - lpg)"
But in thesoftware it is 5 Volts ?

Thank you

+4.4V is still fine for high state. Are you sure is it +4.4V between measured wire and vehicle ground?
It can not be software controlled, it's hardware input, low state <0.5V and high state >3V, so 4.4V is 100% fine and it should work.

Hello,
Thank you for your request.

Maybe it's pwm Controlled...
I will messure again today.
When I look at the Windows software it Switches between on and off...

When I want to read the lpg Status with the gas injectors, the Display is blinking :/

Thank you for your help

It is an pwm signal for the tank valve :/

how do I get it to work?

Change signal source from LPG electrovalve, it will be constant +12V/0V

There was no way to do it switch the tank valve circuit.

Now I have A10 an A11 on the gasoline and the lpg injector...

Everything work fine.

Thanks

Ok, usually this switch is outside ECM.
You can also check C3 signal T-ECT (or M1), seems like it may be ON/OFF controller
