Warning- Spyware With HHO Software!
Mon, 24 Nov 2008 09:40:46 -0800 by rpierini

I followed a link on a HHO video and got a possibly amazing program- and lots of adware/spyware. Just wanted to post a warning.

#18) Hybrid Cell Design Bench Test
Sun, 23 Nov 2008 11:32:14 -0800 by rpierini

I hand built this funny-looking prototype to try and minimize exposed plate edge. It works well- it came out to about 1.7LPM at 11.3V, 26A- not too bad. It would have been better but the Marine Goop insulating the plate edges failed. In my next cell I'll use gaskets like a dry cell, and cut the amount of exposed plate edge in half.

#17) Reducing rust in the HHO system
Tue, 28 Oct 2008 12:47:14 -0700 by rpierini

Some updates: You can do it at room temperature over 4 hours, and you should dry the plates in the oven at around 180* F. I put some foil on a cookie sheet and stood the plates up between the oven racks.

#16)Current-limiting PWM first test
Sat, 25 Oct 2008 14:57:51 -0700 by rpierini

I was pretty happy to get this thing finished and to see it in action! Thanks again to Zero for all his hard work. Yes, I know the ground wire is too small...

#15) $2 MAF Enhancer
Wed, 22 Oct 2008 16:53:13 -0700 by rpierini

Adding resistance to the signal wire of a voltage-based MAF sensor such as this hot-film type leans out the mixture. Unfortunately, the added voltage increases as the RPM insreases-but if you start low it doesn't go too high. It works for the same reason that MAP enhancers sometimes don't: because there's a voltage/current coming from both sides- in this case, from both the ECU and the sensor.

#14)Single Control For Dual EFIE, In Action

Shows a dual EFIE with single added voltage adjustment with the engine running.

#13)HHO system, CL PWM
Sat, 18 Oct 2008 18:02:13 -0700 by rpierini

Shows the basics of an HHO system that was just installed- I was hesitant to show it yet since it's just kinda thrown together, but it will be very nice when done- will have a bigger generator and auto-refill. This generator is small and inefficient, but he's already getting a mileage gain with just 1/4LPM! Also, I have the circuit for a ZFF current-limiting PWM built, just needs to be boxed.

#12)Single Voltage Control for Dual EFIE, 02 Mimic Circuit
Tue, 14 Oct 2008 16:36:23 -0700 by rpierini

2 ideas here as described in the title.

#11) Soft-start circuit for EFIE
Sun, 21 Sep 2008 18:56:36 -0700 by rpierini

At this point it is possible to build a stand-alone soft start unit in which added voltage onset and ramp-up rate would be independently adjustable, and could be used to power any EFIE. This video is to demonstrate a time-delay circuit that I just added to the proportional EFIE. Added voltage onset can be delayed from 10 seconds to 10 minutes. I could also have added the voltage ramp-up rate adjuster, but didn't need it for this one.

#10)MAF Enhancer Update
Sun, 14 Sep 2008 15:49:42 -0700 by rpierini

The new MAF enhancer is working well, and the mileage is good too. Update: Mileage shown here was a 3MPG increase. That was with 50mv added from the MAF enhancer and 14.5 Ohms in the A/F sensors. Before this video I had just turned up the MAF enhancer, and increased the resistance to 16.5, and it's now at 5-6. That's with only gas additives, it's measured at the pump, and it's consistant.

#9) Brand new EFIE concept!
Sun, 14 Sep 2008 15:19:34 -0700 by rpierini

What I'm attempting to show here is a new EFIE design that adds its voltage proportionally to the 02 sensor's signal. From vehicle testing so far, it's looking like the best EFIE I've ever tested- and I buy and test them all! FYI the voltage reduction at the top of the range was later eliminated.

#8)Frequency-based MAF sensor w/resistance in ground
Thu, 04 Sep 2008 08:05:39 -0700 by rpierini

OK, I had to try it. Now this doesn't guarantee that it wouldn't help mileage. But the ECU just didn't seem to like it, and I'm not willing to take the chance. Also, the frequency didn't change when I added resistance. Granted, it was unlikely that it would or could. But if you have tried this and it works, please post a comment here saying so! I'll add a few Ohms and do a mileage test!

#7) 02 Sensor's Frequency and Waveform
Mon, 01 Sep 2008 21:35:08 -0700 by rpierini

This video demonstrates the frequency and waveform of a typical heated, 4-wire 02 sensor. I also show the effect of an EFIE on the frequency. Test vehicle is an '03 Ford Expedition.

#6) Observation of A/F sensors' current
Mon, 01 Sep 2008 07:53:48 -0700 by rpierini

This is a remake, the first posting had the audio/video out of sinc. Anyway, in video #3 I was focusing on the voltage signal of the A/F sensors when it's totally irrelevant. A/F sensors work on current. So, based on these observations I have gone back to 17 Ohms of resistance in the signal wire. Again, OBD2 Nissan can use both front and rear sensors to adjust fuel delivery. I thought it was strange that the check engine light wasn't triggered but actually had a 'pending' code saying "random multiple misfire".

#5) Brand new MAF enhancer concept!
Sun, 31 Aug 2008 17:01:37 -0700 by rpierini

I just had a flash of insight that resulted in this idea. An enhancer for voltage-based MAF sensors that is simple, affordable, and temperature-stable! So simple it's scary. I'll be testing it for a few weeks before listing it for sale. The price will be $40- but if you want one now you can get it for $35. This will also be developed into a new EFIE design that will be at least 30% cheaper than current designs.

#4) EFIE in MAF signal wire
Wed, 20 Aug 2008 19:22:12 -0700 by rpierini

So, what actually does work to lean out the mixture in a voltage-based MAF sensor? An EFIE.

#3) Adding resistance to Altima MAF ground wire
Mon, 18 Aug 2008 15:05:00 -0700 by rpierini

Surprise, surprise! Adding resistance to the ground wire of this voltage-based, hot-film MAF sensor actually richens up the mixture!

#2) Meyer-Type Cell, First Test
Wed, 11 Jun 2008 15:03:09 -0700 by rpierini

Just built this one- It's new, unconditioned, and cold. But look at the production! Draws about 35 amps with K0H 1/2 tsp in a gallon of distilled water, so it looks like it needs some insulation. This cell responds better to PWM's than others I've seen.
