Ok I checked the compression of each 8 cylinders and 2 cylinders have 0 PSI so I need to remove the valve cover and see the issue, I guess I will need some repair in the engine

Without problems it would be to easy and no fun, haha

I've made small progress today too. Volo chip installed; first drive after me - but only 10 miles. First feeling: about 10% less fuel consumption - but it may be purely auto-suggestion, too soon to say. Big plans for connecting HHO on Sunday, if i will have just enough time :-)

Good luck with engine!

The volo chip you have is the HHO FS2?

They are a lot of thing you can buy as chip for HHO, they are one that reprogram the ECU to run better with more hp using 87 OCTANE gas etc... I think this could help, the thing is that cost a lot around 350$, so if I buy that I will program the jeep in my area for 50$ to pay this ECU tool lol

So if you program your ECU with that at first this will help, after add your VOLO or SIMILAR device

Keep me informed with your VOLO i will maybe buy one too, I need to repair the engine first lol

I removed the valve head, now I need to dismantle a lot of crap just to remove the cylinder head, then I will go somewhere to restore the cylinder head/valve head like a new for 375$ and put back everything back and hopefully my jeep will run like a new

Hi again,
So... after a few days break I've made a small progress.
1) VOLO chip installed (Yes, FS2-HHO edition, sorry, i've missed your question earlier)
2) HHO connected to air intake, but on separate accu in my trunk with no electrical connection to main installation.
and... after first drive (about 20 miles) no visible change in mpg.
I'm almost sure the engine is working different, as it is quieter. My DryCell is using 12- 14 ampers. I have no idea how to measure HHO output in liters. I think, that VOLO has to learn how to manage gas.
During the weekend I should drive about 80 miles outside the city and maybe than I will see some improvement.
I'm curious, if about 13 amp is enough to see the difference in 4.0L engine, but I think it should be?

Do you have some ideas ( maybe ebay links to controllers  etc ;-) ) on how to load second battery when there is some free energy on alternator? I'm thinking on some solution taken from camper van's.

Hi Milo, the easiest and cheapest way to measure your gas output is this:
1.  Get a big tub-bucket of water.
2.  Get a 1 or 2 liter plastic bottle (or whatever you have in your recycle bin from juice-soda etc).
3.  Get a long tube to connect to your output line of your HHO device.
4.  Draw a line with a permanent marker every 1/4 way up your bottle.
5.  Submerge plastic bottle in tub of water and place it so the open end is at bottom.
6.  Feed tube from HHO device up into bottle.
7.  Run your HHO device for 1 minute and stop.
8.  Measure how much water was removed from the bottle, either visually or place finger on bottom
      remove bottle so no water gets out and flip over.
9.  Post your results

Yes I see good controller on ebay, some with big amp and smaller one, I did not boy it so far but
they looks fine

I need to repair my garage before removing cylinder head, so I have some delay on my jeep, so lot of work but since my roof is no good with rain, water enter, I redo the roof with new truss it why no update!!

I hope in a month finish my garage and will show the new garage, I received all my stuffs related to the jeep, air intake, GPS Bluetooth with Windows CE and Bluetooth OBD2 device (I will try to use the ODB2 device on it, to see all data in realtime while I drive), I am confident after all the mod, my jeep will be more economic compared to my civic hybrid!

Also about the VOLO, does this chips is good to buy so far? I was imagining you get better mileage even without HHO with this device.
