    Of course it won't be as accurate as petrol gauge let's say, but some indication would be good. At this point I can't calibrate it at all. I'll look into getting a mechanical gauge if I can't figure it out.

        That looks fairly close now when you remove the sporadic high and low values. Reset the Motronic and see what it says.

            If there are no adaption issues you probably are ok.

              I get check engine light on idle occasionally on idle, but not always. Once I'm moving it's all good.

              Was hitting high revs in 2nd gear today, and she started shaking? Should I just adjust the last 2 points? Doesn't happen in high gears.

                Could be a number of things. Really need the wideband. Sounds like the idle part might need small tweaks to try and get petrol and gas Motronic times closer.

                  It isn't bothering me hugely, and if it runs fine now I will leave it alone till I get wide band and I can then have another crack at it to get it perfect.

                    How much gas had you when it mess arround in 2nd gear. Could also be fuel surge. I have big problems with that when in low gears accelerating fast. No baffles in the tank.

                        Ok could try pulling the top points back in the map and try again. You running good plugs and coils? Lpg needs a good spark. When a 1.8t coil pack was starting to fail on my car it only affected Lpg for the first while then it went off a cylinder on petrol too.

                          Spark plugs done back in February and coils I bought new year and a half back so that's all in order, well, should be at least. Do I not adjust the two middle ones at all?

                            You really need to have the Lpg laptop running and see were you are on the map when the car misbehave. Then you know where to adjust.

                              That's hard to do when I'm driving Don't know if it's worth getting a good company to do it for me?
