Just let us know the year, make, model, engine size, to find your OBD protocol. Comes all soldered up and you just plug her into your J1939 OBD Round 9 pin port.

For 1996 to 2025 diesel trucks 12L to 16L. OBD J1939 Round 9 pin plug. One year warranty, you can send it back for a refund, if you do not see MPG gains. Expect 10% MPG gains with just this circuit plugged in your your  9 pin round J1939 OBD port. Most today are CAN protocol. Volo works well with CAN protocol. It can not throw a "check engine" light. Also you feel more HP when you floor it, due to leaned out race car fuel trims. If not hooked up with the correct wires it will tell you with 2 red lights after calibration. If correct after the initial calibration 2 to 3 minute light show, you will get 2 green solid lights. That means it found your protocol and communicated and calibrated, Your ready to roll. This has to be done, while truck is hot and idling and not moving. Learn how to find your OBD J1939 protocol. Can be used alone or with added HHO Hydroxy Gas™  SAVE 10% with the Volo Performance circuit alone, add a Hydroxy Gas Trucker 9x16 cell and see 20% gains total on average. It comes with a you solder in OBDII port  6 or 9 pin plug in. Easy to solder 4 wires to your car/truck's OBD II port under the dash. OR order all soldered up, just plug it in, for another $25.00  Choose below 1) u-solder 2) ready to plug in. We will need your year, make. model diesel engine. Works on 1996 to 2004 best, more simple ECM's CAT & Cumins is proven. Dan the past owner of Volo mapped 20K cars and trucks. Many trucks in Asia, Volvo and Asian trucks. Only works on OBD II cars and trucks (1996 to 2025) Can not hurt the engine, only leans a few fuel trims. Necessary in all Hydroxy Gas™ generator installs. As your diesel engine will run cooler completing the burn, so your CIT and AIT temp. sensors will not be triggered to en-richen the fuel due to the complete burn in the cylinders. No more hot burning fuel down your exhaust manifold.

This chip has been specifically tuned for the needs of HHO generator equipped vehicles. The FS2 is dynamic - which means the FS2 will consider engine temps CIT and AIT, 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. One year warranty. So you got nothing to lose, if your a skeptic. For there are a lot of OBDII plug in devices that DO NOT WORK, nor save of fuel as advertised. They sell for a year and they disappear or come back in another name, different case. Beware. Learn about all the scam resistor chips here. We have 15 year tract record of Volo's No one returns them. 98% satisfied customers. Can we switched to any other car, truck. Just search for the engines protocol. Most trucks are CAN Protocol.

This circuit works by an exclusive process of "Dynamic Soft-Flashing" the ECU. The new FS2- HHO Edition was specially designed to SAVE MPG with or with out the addition of Hydroxy® Gas from a HHO booster cell system. Ships in 1 to 2 days. We program the circuit to your specific make, year, model car or truck.  New B2 model with firmware version 7.6 (7/13) The led lights are positioned across the top, easier to see & a faster micro processor chip, higher Hz. The next closet gas saving micro processor chip is $900! For only $149.00, the Volo FS2 circuit should be way more money$!

Save money at the pump! Pays for itself in 3 to 6 months. Only $149.00 No other fuel saving circuit on the market, as smart as the Volo Fs2 compares to this low price offer. The closest micro processor gas saver to the is $900+

How does it work?

The Volo FS2 & FS3 Chip works by an exclusive process of Dynamic Soft-Flashing the ECU, onto it's own micro processor chip.
Each circuit comes programmed with a highly tuned map and a set of EPROM addresses that directly affect fuel efficiency. When the ECU attempts to read the specific EPROM address, the Volo Chip patches the factory value with one from its tuned map.
Built on the same platform as our popular VP12, the FS2 utilizes the same exclusive patching algorithms to increase fuel efficiency across the map by up to approx. 10% to 18%.

Volo OBD II Install / Solder instructions 2023 OBD II Port solder job.

Either use the provided OBD II port plug or use the 4 wire clip option below. Only 4 wires, behind the OBD II port under your dash, takes about 20 minutes to install. Solder or use the provider wire clips. Locate the OBD-II port, find the car or trucks protocol. Instructions here. The Volo install leaves your OBD II port open for any plug in tool or ScanGauge device, if you use the wire clips or solder in 4 wires.

HHO enthusiasts swear by our time tested FS1. After the recent 7.0 patch, we've come close to the limitations of the FS1's hardware. So we've taken your feedback and suggestions, along with the powerful VP12 hardware, to build the newest in the Volo line up - The FS2-HHO Edition!

Don't want to bother with a Hydrogen Generator? but still want to save gas, Volo makes a FS3 chip.

HHO (Hydroxy® Gas) Supplement Generator for maximum gains. Beware of Junk HHO cells out there. We can prove that our cells will produce a good 80% of "ortho" hydrogen, a necessary static cling gas to carbon. Without this higher quality gas that clings to carbon,  you will NOT see consistent MPG gains! Please read here.

The FS2 is compatible with factory equipped Turbo/Superchargers, diesel engines, Flex-Fuel, & HHO supplement systems. It is NOT compatible with hybrid engine options, propane, or natural-gas.

• Please note Volo Performance sold their fuel saving circuits on ebay for about 12 years. 2008 till 2020, when ebay cut off all circuits that said they improve gas mileage. They sold thousands of FS2, VP15 and VP16 circuits on ebay. They were kicked off. I believe the plan ( GM, Ford and ExxonMobil) was to sell Bull Schiff OBD II plug in gas saver plugs, that did nothing. They changed the name 3 times, that I know of and a new different color plastic case, a new name and advertised a million times, then they go under after 6 months, no refunds and no warranties. To give a bad taste to all motorists. Bob Boyce™ recommends the Volo circuits, because they work! Volo could never get SEMA or CARB approval, because it makes motorists think, how come GM or FORD does not lean out the fuel trims? Why sell gas guzzling cars? trucks? It is all about the $ in this life. We have been selling Volo circuits with and without or Hydroxy Gas from water kits. From 2008 till today! 15 years of good results!
