I checked 0 angle and strobe shows -3degr. but changing octane correction not reacts. I used real time map.
It should work.
CE output is connected to relay as GND to invert output as + . my dash needs 12v to activate lamp. but lamp dose not go on .CE is forced to display .
do I miss something?
Make sure your relay actually works.

CE output is not working and octane correction too.
1. Can YOu in next relies add ce output to be remapped to other outputs . That CE also can be on positive output.
2. Octane correction dose not change any readings with stroboscope.
3.I am installing lpg with "Gas dose". OK
switch to petrol car runs on petrol.
switch to LPG . LPG solenoid opens. "GAS_V" turns off fuel pump, switches to gas map and gas dosage and all that belongs to gas.
But from fuel to gas I have to empty carburetor from fuel. how to do that without installing fuel off solenoid, sense I have electric pump
Image

4.Or do I need this switch? Gas_V+12v switch activates secu gas map, kills fuel pump and one of secu outputs unlocks gas solenoid when it see engine turning.
5.If I use LPG carburetor with gas dose , I still use secu-3t_m644_rev9_dwell.a90 ?

We need to be able to change the output properties *FE* and *IE* to exit *CE*... :ugeek:

Hmm, interesting suggestion. I will add it into the TODO list.
Если я правильно понял твой Английский, то ты имел в виду возможность переназначения СЕ на IE, FE.

Hello.
There are many accessories unknow for me in the gas systems catalogues.
Is there a relay for the electric fuel pump? Does a wire from ignition key turn it on?
I think that it takes to use the wire from the petrol/gas switch instead of the one from the ignition key.
I don't know if it's the right way.
Bye.

Hello.
Sorry if I disturb.
May I ask some questions,please?
I'd like to know what LPG system you're going to buy,I'm interesting in the regulator,the petrol-gas switch and other electric accessories.
I can't understand what they mean about some regulators and switches for cars with a carburator.
Maybe they're discontinued parts or they can't be approved everywhere.
I hope not to be wrong about Secu-3 and the second ignition map selection for LPG.
"Gas_V" is the imput to select the LPG map,right or wrong?
The wire from "Gas_V" is connected to the LPG solenoid valve.
Is it right?
If it's right and I'm not wrong the Secu-3 doesn't mind if there's a mechanical petrol pump and petrol solenoid valve or an electronic injection or an electric fuel pump.
I don't know how to use a relay in the right way and how many sorts of them there are.
What sort of relay did you use for the elctric pump?
Once upon a time they used a tachometric relay.
Tachometric relay.jpg
It was a safety device because it used the signal from the coil,if there was no ignition it stopped the electric fuel pump.
After that device they introduced a sort of button on injected cars,I don't know its right name.
That was easy to understand and to use.
Now the confusion is about LPG/CNG systems...
Safety switch.jpg
That was used on a petrol car with an electric fuel pump like a tachometric relay.
Safety cutout.jpg
The second device's vendor said that it also can be used for fuel electric pump on petrol cars.
I think that it's a good tip.
Then I found a petrol-gas switch for cars with carburators,the same you've shown.
Tachometric relay-Explication.JPG
I don't understand what they mean,there were no schemes.
Maybe there are other devices or safety modules.
Will you fit a LPG level gauge?
Thank you all.
Bye.

Switch for "fuel-gas" for lpg Image is replaced with secu fuel pump output thru 2 relays.as schematic above.
the original lpg switch is as safety. when engine is not turning solenoids are closed for gas.
secu fuel pump dose same function. secu fuel signal opens when engine starts turning. (same thing)
The gauge is going directly to my dash. so I can simply skip that has switch and use any 3 position switch.
any 12v car relay can be used. Image
and connecting Gas_v to gas relay output secu activates gas map and all other things that belongs to gas map, like gas dosage.

Ill later update full schematic as Ill connect gas system
