Insignia OPC

Hello Guys,

sorry for English but i need your help

so i finally installed LPG to this car and i have some problems. It seems, that there is some problem with reducer, because we adjusted reducer to maximal output power which had to be 1.9Bar but it show only about 1.5Bar on idle, but when i run on boost it seems that pressure is still same 1.4Bar and no more. I suppose that if i am on boost reducer must adjust pressure more than on idle. So this is strange for me, also this affected the map as is visible on the picture in link. Another problem is fuel pressure emulator, which seems to work somehow, but i got P069 code, which mean problem with fuel pressure regulator. Otherwise i have all this problems it seems, that car works perfect on LPG. Fuel consumption about 14l. Could please someone advise where can be problem? Many thanks

I read on this forum, that emulator AEB type 0 will work for this car, so i will try that first before i will create return line. I still do not understand why i did not have same line on the gas and petrol on higher load? But car is able to worl normally no any judgering, etc... Could you please advice what i need to change to improve that? Many thanks guys

 

So if you check my seting and map, what i need to improve or change, to get better results? i still do not understand why i have there so big difference between gas and petrol on high load.

 

Behind throttle body.

Uff i do not know, but if i will try to make same line on high load (mean gas will copy petrol) car starts to hesitate on high load.

 

I mostly check short and long trims during ride and try to do adjustments depending on the value, but LPG unit has also OBD inside, so it monitor trims and makes adjustments on GAS depend on that. I have setuped that if the trim exceed +- 3% it will start to make corrections. On the long trip i had about 2% of the long trim so i think that setup is ok. Car works perfect on LPG. I am just surprised, that there is so big difference between those two maps. Is it possible to keep it like this or will be better to lower down the reducer pressure?

 

I tried to contact KME with my problem about pressure on this reducer and they replied me, that there is sometime stucked some plastic part under valve. Is possible, that this causing difference on my gas map on high load?

 

To which value do you think is optimal to lower down this presure?i think also that i have to big nozzles...

 

Guys, could please someone tell, if the fuel pressure emulator in Staq qmax plus works here on insignia? Did someone of you tried that?

 

Hello Guys,

so finally i tried to use a AEB Type O emulator and it works like a hell. No any MOT, looks like pressure is same on gas and petrol. This emulator really works perfect and no need to cut wires.
