EFIE schematics
I'm wanting to build one of these over the 3 day weekend but I cant' find any schematics. Anybody got one?
Also, if you have them, I'm looking for schematics for an Air Fuel Ratio Meter and a Pulse Width Modulator. Thanks! |
I know I've found all of these here before but I'm having trouble digging them up again. I usually save this stuff when I find it but I can't find any saved copies either.
I did find this AFR meter on google: https://www.scirocco.org/tech/misc/afgauge/af.html I found this DIY PWM on google: https://www.rmcybernetics.com/project...generator2.htm Here's some EFIE digging... https://better-mileage.com/memberadx.html https://www.youtube.com/watch?v=PEHJ9te7gvk https://www.esnips.com/doc/718eacd2-0...nhancer-Manual (or download at https://www.esnips.com/nsdoc/718eacd2...action=forceDL ) I wish I could find the ones that have been posted here before...I remember some pretty decent ones a couple months ago. |
That is too awesome, the parts for the AFR meter can be had for free!

I don't know your background but be careful with the PWM. make sure it can handle the current you plan to put through it.

Almost free for the AFM. I ordered 3 of the LED driver chips for $13.

I'll have to look and see if I have any information on a PWM or not. I know I don't have anything on the A/F meter.

dude, I work with fets all day every day. that doesn't mean anything. a fet or field effect transistor doesn't specify current carrying capacity. the ones I work with will only handle about 13 miliamps per cell. obviously there are several cells paralleled.
engineering gets it done remember, heat sinks and silly grease (conductive silicon grease) and you can parallel them if you need to. you could also go so far as using a cooling fan but now you are reaching the realm of just buying one that is pre-made. |
I started ordering parts for the EFIE. I got the 5.0v Voltage Regulators in today.
https://www.fuelly.com/attachments/fo...091f59ba3b.gif I can't believe how tiny they are! Part number is LM38690DT-5.0 and they're free from nsc.com. What threw me off is they shipped to me Next Day Air. Totally wasn't expecting that. BEEF, I don't plan on running toooo much off this PWM, I got it working this weekend. The transistor I went with only handles 5.0 amps constant(8.0 peak) so if I do in fact build an HHO cell to try in the car I'll need to build a daughter board that the PWM drives. |
