At idle it's a bit rough, under load it feels like it's starving, at 2200rpm when under load and on a hill it feels like it's not getting enough fuel. Changing the fuel map is what I find difficult as I don't know what I'm doing as there are too many boxes with settings in them.

actually, last saturday I have change the tires. the old 245/70 R16 I changed to 235/70 R16, which is one of the original size ( but in real it was 1 inch difference in the diameter, I don't know why ? ) , and even if this is a small difference , I saw some improvement especially in acceleration. Idle and under middle load working fine, but as example during changeover I always feel a small pause, like can't deliver not enough gas right at the beginning. Maybe this is also because of pressure issue, or I would need to improve the overlapping time.
The most interesting thing for me was, that even if I try to change the map, the fuel consumption doesnt changing or only with a very small amount - I am always around 20 liter / 100km ( from 19 to 21) - but if I am thinking about the pressure, it could also possible, that all these changes doesn't have a 100% effect especially because of to low pressure ?? ...

regarding map I agree, too many boxes, nort so easy, but I am trying to change the values with possible smooth transition, without too big gaps.

The actual pressure is set by a screw on the regulator/reducer. The programmed pressure is the design objective so the signals sent to the injectors match the injector response times.

I set the overlap to zero, it is not needed under normal conditions. Using sequential changeover it changes one cylinder at a time and should not surge.

Always save a working copy of the vehicle settings so if you have a bad map you can always reload the old configuration. To change the map, press the right mouse button and drag the cursor across and highlight the area you wish to change (or even the whole map) then press enter, change the numbers by +/- 5 or 10 at the most, press enter again. You can also practice on a base map with the ECU not plugged in to the laptop.

hmm, I am a little bit confused...
The reducer was setup via screw - if I see pressure 0,78, I cannot change it via programm, it is just an info about current setup.
The pressure I can set up in programm, is for injector settings.
In my case I should decrease the pressure value to the 0,78 (instead of 0,95), and the injectors will work with the current valid adjustment.
Or, I need a screwdriver and I need to adjust the reducer up to 0,95, and then the setteing for injectors will match the setting for reducer.
Is that all correct?

Yes, I always do that. But to be honest, I am very carefull and I make only small changes at once, because I am still short of knowledge. The main reason I started to playing with settings is, that my original setting were so bad, that I was almost not able to drive, after finetuning it became even worst and I was afraid, that it can mechanically damage my car ( I thought first, that my driveplate in gearbox is broken and I was not able to drive over a small hows - with a 4.6 V8 engine !! ) Then I decided to buy an interface and I have reset the map - since this I can at least drive till medium load.

If everything goes fine, friday I am going visiting a specialist, but actually it is very hard to find a good one. so I will see.
but in the main time I will looking for some backgroud info - I am doing the service for my Range, so I hope, I will be able to maintaine the lpg too.. I just need the knowledge and understand the context.

so far thank you very much for your comments.

by the way, I have this reducer:
Elpigaz - Vega-i Sport

my system is Elpigaz, this is a pretty good copy of italian system, and this is certified in my country ( only certified systems and only by certified technicians can be installed. and also only by domestic garage! I guess, in Europe we have only 3 countries with such a sctrict conditions

Your system design pressure is 0.95 bar. Please adjust your reducer pressure with an allen key in the hole in the middle of the silver part on the right hand side of your reducer so that the gas pressure read by the pressure sensor at the bottom of the programming screen is 0.95 bar approximately.
