Those who run LPG converted 2.2's

It works on LPG now but is very rough on idle, rpm is jumping up and down and once it even stalled. Shakes like hell under high boost. Below are some screenshots that came out, I don't know what I'm looking at tbh.

Take a screen shot of the screen that shows duty cycle and rpm when on petrol and then repeat on gas. Have you the narrow band lambda sensor connected?

How do I connect lambda again?

[hunker7]

these two? Ms on gas jumps up and down between 3 and 7 ish when idling.

Grey connector 4a. Connect it to the wire that comes drink the sensor that is between 0 and 1 volts. Normally 0.45 at idle.

It looks too lean. Increase gas pressure and try. Motronic is increasing its ms so it's wanting more fuel in gas as gas setup is lean.

4A was the violet wire, so that's now connected. It doesn't allow me to increase working pressure above 2 bar?

[hunker7]

Now that lambda is connected petrol and gas ms is pretty steady ~3 for petrol and ~8 for gas

How does it drive now. This is where a wideband kit is good.

Idling is rough, but drives fine until it's about 0.5bar boost when it starts to shake like hell.

Try increasing and decreasing the multi to see how idle changes

multivalve? or MULT tab in #181 second screenshot?

Multi tap. Its a crude way of scalling up and work the complete map. At minus 40 your leaned off a lot.

OK. I'll try and get that done tonight if I get a minute. How do I know when to stop, sorta just see how it runs?

[diesel des]

Yep. Then fine tune that graph. It allows many points to be adjusted. In just trying to get you almost these with multi
