It's a dual fuel system, installed here in Bulgaria.
Here LPG and CNG are very common because of price of fuel. A litre of normal gas cost 1.90 BGN and a litre LPG is only 0.80.
My system is LPG injection, it have own ECU that read gas injectors times. Also have some sensors - MAP and LPG pressure, temp and water temp. So LPG ECU calculates its multypling factor and opens LPG injectors with that precalculated time. I think it have injectors emulator to fool ECM they work. And there is no need to fool other sensors.
Its a smart system and not expensive, $400-$1000.
Back on my problem - my EGR is newer type without vacuum actuator but with 6 pin connector. But it don't have extra MAP as you mention in the EGR section. I blow all passages with air and wire and they seem to be clear.
Do you know what the 6 pins are for? Can I plug that EGR?
Cheers,
Ivan
