Fuel Saver Flash Chip?

Has anyone tried one of these? Supposed to adapt fuel map continually for most efficient operation...HHO or not. Might work with fuel additives also.

Advanced HHO - A Leader in HHO Hydrogen Dry Cell Systems

Are other brands or types available?

If you're going to try it, go straight to the manufacturer and save yourself $60.
Volo Performance - Chip Tuning Made Easy

Although most of the people in this forum think using HHO is crazy, I have seen some success with it. I'm not doubling my gas mileage like some people claim, but it does seem to allow you to lean out an engine more than with just gasoline. When I get a new car, I plan on getting my HHO system on a dyno for 100% scientific data. But I won't get into that right now.

I tried using a Volo chip with HHO and I got about a 10%-20% increase in MPG. the car I was using had some mechanical problems, so I had to shut the project down. But I did see some success with the chip. How the chip works, I got no idea. I also don't know how it would work without HHO.

I do know the chip you'll want is the FS3 and they claim 15-18% increase in MPG. If you're interested, I say order a chip, and do some ABA testing. All of us in the forum would like to know the results. Good Luck!

Sorry to double post, but I read your second question. this is the only chip of it's kind I have ever seen. All the other ones are resistor chips, but this one actually has a processor in it and onboard ram(I took one apart). I don't know if that means anything, but it gives it more credibility. I think it's worth a shot.

I've tested my own designed HHO and also have used an EFIE and modified sensors...but one vehicle was carbed...the other was 4x4 and 1st year EFI. Could not claim I saw a gain.

This chip looks to be no more costly than an EFIE...and looks to also "modify the other sensors" at the same time. Fairly easy install and will work with an SG? Not sure what if any changes I would see with the SG readout though. Might try one.

Looks like the FS3 would be best...but the FS2-HHO seems to do the same thing and also adapts to HHO.

thanks

Too bad the EFI on your cars lacks sensors and an ECU to make constant corrections...

Well said.

The maps can probably be leaned out - if you can get at them.

The "maps" don't really matter once it gets in closed loop.

For those whose minds are not running in "closed loop"...here's a link with some reviews...

Volo Performance Chip Results


I MIGHT try one of these and then dust off my old DIY HHO machine and test it next summer.....in her prime she could run 15-25 amps and not blow up! ;-)

Suspectnumer-i didnt realize you were using hho. So fs2 would be best.

Not using HHO currently...but have a DIY system. Might try the FS2-HHO since I have the HHO unit and it might be more sensitive to the use of fuel additives.

As far as I can tell...these dynamically adjust the air/fuel/timing in closed loop....over-riding the ECU to some extent....with the intention being greater fuel efficiency.

I'd have to see around a 10% gain for payback in 1 year though.

Do have an EFIE and know how to do sensor mods...just hate to start hacking the wiring.....
