From the start, I have had a hard time working with cars that have EFI systems, Japanese cars in particular, as their ECUs (car\’s computers) are really locked down tight.
The biggest fuel mileage results have come from, ironically, the big american beast SUVs, that have lots of room for improvement.
the issue with the tightly locked down cars, like the Japanese cars, is that the ECU monitors, via the O2 oxygen sensors, how much fuel is being burned. If the moe-joe cell is installed (the same applies for an HHO producer, in this case, though the method of operation between the two types of cells is very different) and the moe-joe cell is supplementing fuel to the engine, then less fuel is burned, and the O2 sensors pick up that there is not enough fuel being burnt / consumed, so the ECU causes a greater amount of fuel to be injected into the pistons, which ends up leveling off or negating any benefits from the cells.
i have tried some products that have not seemed to help or work. I have even rigged up my own simplified circuit to trick or diminish the amount of voltage that the O2 sensors are sending to the ECU. these solutions didn\’t work.
Now, however, there may be a solution that has a lot of promise. My friend Dav, also here with us on Nutopia, suggested a product called VOLO – which can be connected to the ECU port on the car (OBD-II), and specifically chosen for make and model of car.
This chip has been specifically tuned for the needs of HHO generator equipped vehicles. The FS2 is dynamic – which means the FS2 will consider oxygen levels in the exhaust, along with engine speed and load, intake air temperature and volume, and many other variables to determine the most efficient fuel delivery rate and timing at up to 256 separate load points.
When using HHO as a fuel supplement, the FS2 will adjust fuel delivery and timing to optimize efficiency.
When HHO is disabled, the FS2 will automatically re-adjust and switch to highly efficient, non-HHO enhanced maps.
So, I am trying it out. I welcome you to do the same. it\’s not too pricey. only $90. worth a try. Gas is so expensive, should make that back in no-time.
What kind of success did the VOLO produce for you, Moshe? I see no report of findings in this thread.
No success. I have yet to find any O2 sensor trick that works.
All the positive results we have had, or that I have heard of, have come from straight installation without any other tweaks.
However, that is not to say that ECU modification would not be helpful. This is an area with a lot of room for improvement, I am afraid.
