Hose barbs I have if you need a 10 pack, 3/8 x 3/8 Nylon.. most stores don't carry these and home depot or lowes or they might carry a few if your lucky. never be without barbs again if your making your own cells. Ebay item 250267329649

Where is the SCHEMATIC for the 1.5 volt battery simple circuit? You say it is there but it is not.

Hi cuja. Your best bet to see the connections is to check out the wiring diagram for this original adder on my other site. I just tried it because I wanted to just give you the link to it but their servers must be down right now. Go to this site: w w w . m a d c o s m . c o m Go to the Photo Gallery (you'll see the link in the nav bar) and the first album you'll see contains the diagrams for the original adder this video was about. It shows all connection points. :)

I study that with the much newer COSM but not with this original adder device.

hi Mad, im trying to copyand the red gromet is in the way of the wiringwhat connects to the negative of the battery ?do you just ground it out with the potentiometer ?thanx

Have you verified this with a change in block learn & intigrator values (long & short term fuel trim) from the ECU?

I hooked up the eife to the same relay as the cell so they run together. My cell relay is powered via a microswitch at the throttle so the moment I touch the throttle it switches on along with a solenoid valve that opens right where the hho enters the intake. This way there is no delay waiting for hho to reach the intake. Don't think hho does much good at idle. How about a pwm designed to increase production as accelerator is depressed? A pot controlled by throttle?

My newest efie was made from 2 - 10Megaohm resistors and a 1 megaohm potentiometer together reducing the 12-14v from car battery. This gives me a variable adjustment from 0-2.5V that I can add to o2 sensor reading. I just experimented since I know nothing about electronics and this works good. Don't have any issues with unregulated 12-14v voltage input.

Thanks for your help.I'll be checking out your other videos.

You could use resistors but your supply voltage could surge and sag. Instead, you want to use an LM7805. This is a voltage regulator that outputs fixed and regulated 5v DC power, then you can limit output with resistance. I went to this on this older model box before moving on to the more current COSM's (the successor to the "adder") to eliminate the penlight battery as well as making other features possible, such as meters and such.
