3/20 - 8/22 - Only use Firmware VP16 - 0.68.29 for the PWM section
of VP 16 Touch Screen Menu. DO NOT USE the newer
firmware versions till we make it public.

Only PWM#1 is hooked up. PWM#2 does nothing, for future update.

The frequency of the VP16 right now is set to default at 150hz.
Working on adjustment from 1 hz to 200hz. for the future (8/21/22)

150hz is working fine with our PWM15 and PWM30.

Download our Volo Vp16 Engine RPM to HHO Engine.map below.

Simply right click on the .maps below and save to your desktop. Save the same name as written, do not re-name it.

the USB drive into your USB drive slot. When you open up the Vlink16 software you can click on PWM mapping and open up the file from your desktop. Then save to the SD micro card inside the USB drive holder. Take out the tiny SD micro card and place in the bottom of the VP16 touch screen box.

S7 HHO cell • RPM .map

D7 HHO cell • RPM .map

S16 HHO cell • RPM .map

Watch out some PC's will open this file in WORD and label it .doc no shown
and will not work.

The map runs off your RPM's while driving, and the amps will go up and down slightly as you drive. We took a S7, D7 and S16 cell and rated the gas output to the amp draw, in a chart to the "Duty Cycle% On/Off" adjustment button.

Example 10 = 10% duty cycle, 20 = 20% duty cycle. ( 20% ON and 80% OFF, the square wave pulse that shocks the water molecules into the (-)ortho spin state.)

On the controller above. Duty cycle = amp draw. Volts stay the same
average 13.5v. Duty Cycle % ( On/OFF times of the square wave pulse = Duty Cycle) The higher the % the more gas output and more amp draw.

You can adjust duty cycle output to the HHO cell (amp draw)
by making your own .map table by RPM that comes from your ECM.
Use this text file to make your own RPM .map

The phone cable connection is only using 2 wires the 2 on the outside of the 4 wire jack, only (-) and power (+) are used.
The (+) power signal wire : 5volts + sets the mosfet driver chip.

HHO and Volo VP-16 Testimony

The D7 HHO kit is working great on the VW Touareg now.  I really like the Volo16 and w/ hho the engine feels completely responsive with more power in the low rev range and enough power higher up to keep the transmission in 6th gear as low as 70 km/hr. In the past it would slow down and then downshift for the smallest uphill. Honestly, If I didn't have this kit I would get rid of the vehicle. That's how much I hated the engine characteristics not to mention the 13 mpg. 

I had some experience producing and editing fuel and ignition maps for ICEs before. That said it was very easy to make a map for hho output. I used mass air flow and load as the parameters and only had to back off the hho a bit under hard acceleration and high load. If you or Kevin are interested I believe there is a way to share maps with Volo via their software.



VP1 installed on a 2013 Chrysler Town & Country Van, went from 18 MPG to 26 MPG! Just the VP16 controller. This customer said it worked better in Sport mode and also better MPG in Sport mode. 9/2020


2004 Ford Expedition, went from 8 MG to 12.5 MPG, just with the VP16 installed. 9/2020


2003 Volvo XC-90, installed a S7 Tool Box Cell Kit. Went from17/18 mpg.
(stock mileage at Volvo site) to 24.7 MPG hwy mileage. Around town 21.4 MPG.
Can feel extra HP. Using the Volo VP16's PWM feature, sending the RPM signal to duty cycle % to control the amps inside the tool box. 1.5 amps at 500 RPM's to 6.5 amps at 3,000 RPM's. Watch the video. 9/27/22
