Hi. I am preparing another video or two of other installations and I intend on doing a voice over so that I can explain some of the steps. I will do my best to include the diagram for the connections. If you have something in mind you can ask me.
@mitchoniauto did you run hoses from the injectors into the intake? Usually I see injectors going into the intake. Still learning about this system tho
@@peterhoughton1731 Done 200.000 kms. Didn’t have the upper cylinder head lubricant system rigged up at first. Got head issues with it later on. Replaced the heads with new gas heads, lubricant kit. Got a new timing chain, radiator,water pump, hoses, brakes, etc. Spent 6k. Good as gold now.
@@bigboy9983 I have a 2005 Honda s2000 which as only done 38k miles since new, converted to Dual fuel LPG at 19kmiles, professional job done. No problems other than a recent PO172 running rich code which also happens on petrol. I was told s2000's didn't need the upper cylinder lube system by the professional installer but I'm tempted to get one fitted now.
I'm curious, how much advantage is there in this injection setup compared to using the old tech version which is evaporator and mixer? Is the fuel economy notably better, and if so, how much?
The main advantage of this setup is that you do not have a big body (intake manifold and tubes) full of flammable and explosive mixture. The fuel (LPG) is delivered right next to the original petrol injectors in small quantities and thus eliminates the risks of explosion. The fuel economy is also better since the idea of the fuel injection is preserved. The evaporator-mixer idea is pretty much an LPG carburetor. :)
Can you help me figure this all out, I can’t outright buy a full kit. What’s each coponent called within the kit? (I have a 2004 Buick century 6 cylinder I want to convert). Thank you for this video and your time.
@@mitchoniauto hey question if I do this could I use the gas inuse at home for heating and cooking to fuel up my car? I mean why go to a petrol station and pay extra to fuel up your car when you are already paying for gas at home
@@goransvraka3171 You have LPG (Liquefied Petroleum Gas) at the fuel station which is a waste product in a way from producing gasoline and diesel and it is stored at 10-12 bar (145-174 PSI). The gas at home is actually Methane (Natural Gas) which is available at some fuel station for powering up cars as CNG (Compressed Natural Gas) but it is stored at around 200 bar (2900 PSI !!!!!) in the fuel tank in the car which could be rather unsafe and dangerous.
So installation does not look that difficult but my question is when you turn on the LPG how does the car computer know to turn off the gasoline or does the system plug into the ECU and turn it off?
It is definitely not necessary. This is and old trick used a long time ago with old conventional/vaporizer systems with carburettor engines. With this set-up the engine operates just like on the original fuel - petrol (gasoline).
Hi! This whole system mimics the petrol injection system and actually replaces the fuel completely. When the LPG reducer reaches a high enough temp (35 degrees Celsius) the LPG computer switches off the petrol injectors and swithes on the LPG ones. When there is no high pressure (threshold can be adjusted) in the LPG rubber lines this means the LPG fuel is getting low and all is swithced back to petrol automatically.
The thing is that the LPG injection systems mimics the gasoline one 1:1. The goal is to make everything right and fool the ECU that engine still runs on the factory fuel (gasoline). So the installation is important, components are important and settings of the LPG computer are also important. To answer your question: the ones on the right engine side are 1-3 and the ones on the left side are 2-4 (like the gasoline ones).
@@mitchoniauto I think you wrote the order when you look engine from inside ,from front looking the firing order/lpg injections order should be 3-4 1-2. The point is we have just installed lpg system(2003 forester xt) and there is a small lag/shake in first move,when pushing gas pedal in LPG in delays/shakes like 1 second then moves on,but in high speed there is no problem. We are thinking there is wrong order in installation like from front; 2-4 1-3( we think problem will be solved when they change 2-3 order like up) Do you have any idea why this lag could happen? Sparks newly changed,coils seems fine because there is no problem in gasoine,only LPG have this lag/shake in first move. Thanks
If there is some wrong wiring in injectors you will have bigger shakes in engine. Since ignition system in 2003 Subi is not coil-on-plug you may have to check the high voltage cables from ignition coil to spark plugs.
@@mitchoniauto Thanks but XT engines doesn't have cables between coil-plugs :) www.subaruyedekparcalari.com/forester-atesleme-bobini-20cc-20-xt-2003-2005-pmu803
Sure! No problem at all. I have converted a 3 cylinder 1000 cc Daihatsu Sirion and the guy was absolutely happy with the car and it is still driven by another person.
@@yasenpetrov99 no problem, I understand you. But the thing is SUBARUs have their exhaust manifolds below the engine since they are flat engines. Can you give me the exact time in the video where you see a problem? Thanks! Cheers!
I am not familiar with this engine to be honest, but as far as I can see there is no reason for it not to be suitable for conversion. The LPG tank will occupy some space since the van is a 7 seater.
Actually the whole idea is to make the car petrol ECU 'think' that the engine is continuing operating on the original fuel ( petrol, gasoline, benzine ).
Hey mate, From Australia and thinking of buying a cheap forester as a run around and wanting to do an LPG conversion on it so I had a couple questions. What size LPG tank did you manage to fit in this Forester? What sort of fuel economy does your mate get with LPG? What ECU would you recommend? (I'm thinking ALEX Nano) Cheers!
Hey mate! Sorry for this late reply. The LPG tank is 56 litres and at 80% it holds around 45-46 litres. Fuel economy is like 11-12 litres per 100 km. What is the price difference over there with you?
Why would you put the ecu behind the reducer , over time excessive heat can damage the ecu (mainly drivers for the petrol injector emulation and gas injector control)
Hi there! Nowhere in the engine bay is cold. Excessive heat may be present only around the exhaust manifold. For sure there is no more heat behind the reducer than anywhere else since the reducer operates at engine temps and even lower because it has to heat up the flow of LPG at all times.
@@mitchoniauto Take a thermal camera and look behind the reducer and compare it to where the car's ecu is normally , there is a big difference even after just popping the bonnet of an engine that has been running for a while, there's a reason why decent ecu housings are made from aluminum and have some sorts of fins on it to work as some sort of thermal dissipation
I little late answer to your question but I think it might be used for that. Maybe if the car is a turbocharged one. I can actually try this on an AUDI A3 that belongs to a friend of mine. It is a 1.8 Turbo.
No issues. The car is being driven every day by a close friend of mine. The parts in the kit were actually selected by me from a local LPG parts shop. These are LPG reducer, LPG injectors, LPG tubes and hoses, LPG electronics, LPG tank and LPG filler.
Hi there I have just installed LPG system, problem I am having is after 15 20 km driving Yellow light flash with sound and turn back to petrol ⛽️ mode. When turn of the engine and turn on it become normal condition. It’s happened again and again. What could be the problem anyone have idea ? Thank you
Hello! What is the electronics of the LPG system? What does it say when you connect a laptop to it? These usually have pretty good diagnostic messages.
@@mitchoniauto thank you for reply. First and second day bit problem after next day completely fine. Very happy with the results. Feels like I should have done long time back.
Man wish you were saying something, just talk through the video, I got nothing out of the video bro, and I DESPERATELY NEED TO KNOW IF I CAN USE THIS ON MY CAR
Hello, my friend, I am right here and will try to answer all your questions and hopefully give you some advice. I will make videos in the future in which I explain every step of installation.
@@mitchoniauto Thanks for responding bro, I really would love to set this up on my 2004 sonata, Is it possible you can give me a listing or a link to to all the things that I would need to purchase?
Yes, after I made the hardware side of the installation - LPG reducer, LPG tank, LPG injectors, tubing and so on. After all this is done and double checked I went to fill some LPG to LPG station but not the whole tank ( a put let's say 10 litres ) because I needed to check for leaks ( I never had one but this is important ). Then comes the software part of things and I must say that every LPG ECU I have worked with comes with a build-in algorithm for initial settings.
I don't expect any of these with this engine. Subarus are OK with this. Hondas on the other hand are known to have valve problems when being used for a long time after conversion.
how did u split up your coolant hoses for the reducer? What is the Intake hose and what the Outtake hose? Did u installed it in row to your interior heater or parallel?
I have done both on different cars/engines. On another SUBARU I did it in series with the interior heater and on this particular one it is in parallel with t-junctions. They can be 16x16x16 or 19x16x19 and so on. www.lpgshop.co.uk/t-and-y-junctions/
The installation kit for this conversion I bought from a local supplier. A good reference site would be this one www.lpgshop.co.uk/lpg-conversion-kits/

@@mitchoniauto Rust prevention.
Does it switch between fuels or just supplement the gasoline?

Hello! Unfortunately I do not speak your language and cannot understand what you are saying...
The reducer should never be installed in that orientation. He should have installed rotated by 90°
I cannot agree with that. This was true for the old style installations where the Reducer is a Vaporizer and there the pressure is very little. ;)
It will help if you use words (speak) so that people can understand what you are doing. Not very informative.
