These two hoses are from the pressure sensor and gas fumigation nozzle I will fit these off to the air inlet

Well it has been a while since I have done work on this project, my new job has seen me time poor for several months now. Recently I fitted off the ECU unit and some of the components. Have wanted to do it in a way that did not distract from the engine bay layout. The voids in the front guards have been useful to achieving this. Wanted to keep the engine bay looking tidy. Here are some images[IMG][/IMG] Made a bracket for the micro processor and the 3 fusses on the loom, it also has a series 3 fuse box which supplies power for the LPG system, driving lights and any additional hard ware to fit later. I think I only drilled one hole on the lip of the guard to get it fitted on. Wiring is within the guard with conduit running under the radiator shroud to the other side for the gas solinoid, convertor, pressure sensor and injector set up. The later is I think type of stepper valve. [IMG] The pressure sensor sit on the inside of the guard so is not visible , worked out better for the wiring and I wanted to keep a section free to put the licencing plate on for the fitting of the unit.

The convertor sit inside the guard with the water hose fittings pointing towards the water pump need to figure out how I am going to plumb it up next. did think of removing the temperature sender as I have a small digital one fitted. Just not sure on which way best to do that yet. I had to move the steering pump reservoir across a tad and the gas hoses again fit inside the guards so they do not intrude in to engine bay.

SubscriberG'day Gaz,
First look at this thread. It sounds like you picked up a good gas system. It'll be interesting to see some fuel figures once it's all up and running on an Isuzu.

Yes I am interested in the fuel figures but also if it soften the noise and rattle at low revs as the diesel and gas have different flame rates so the ignition is not such a big sharp bang. Thats my theory, hopefully someone can shed a glimmer of light on that point. Otherwise just have to wait and see when its up and running. The other thing that has always appealed to me is the fact that diesel/gas setups result in a cleaner burning more efficient engine and seeing I have an environmental ethos it would seem good practice.Originally Posted by rijidij

Adding some BioDiesel will go a way towards reducing that clatter. I used to run 80 to 100% Homebrew. Also made the engine more tractable at low RPM.

Yes bio diesel was one of the things I considered but I just do not get enough time at present to do much once the projects finished then maybe look into it. Have check out bit on doing it and there are a few variances in making it. It seems like it would be just another project to do at the moment and I really need to tic a couple off the list first.

Went to an LPG fitter today who guys in the trade says does really good work, he can finish the fit off once I have a schematic diagram to make sure every thing is wired as should be. So emailed Diesel Gas Technologies (DGT) who made the sequential 2 unit so I hope they able to help out . It is such a shame they are in NSW it is just to far away to travel to get it done as I have sio little time. Two things Shaun the LPG fitter said were that my gas regulator is within the crumple zone in the guard so will have to move it that no to major, so will place it near the brake master cylinder. The other thing he said was if anything went wrong with the system it a trip to DGT to figure out whats gone wrong that would be a real pain. SSo he suggested requesting if the software is available so I could find faults when they occur without taking a long drives to have then rectified.

I wish you luck getting the software, you'll probably also need a dedicated tuning cable, and they may charge you a hefty fee. I paid about $180 (once off) for the licence and cable for the petrol injection I use. Not for nothing did I develop my own mechanical delivery for diesel gas enhancement. It needs only a couple of knobs adjusted to tune.
Master
Yes getting the software and the tuning cable left a message with them over a week ago no response. Pity I think its a good system but not much use if you can not diagnose whats happening and you have to go to Sydney or up to Wodonga when they are down there. A bit of an oversight on my behalf at the time I bought it they still had someone in Melbourne. But since then they have retracted service centres to about 2 locations now and they are not in Victoria. So not sure what to do.
