O2 map/maf Enhansor thingie <grin>

This is some pics and info that Scratch1676 posted on another forum
I coppied the pictures ages ago thinking I will need to make one soon, but still havn't done it ! HAHAHAHA
...
below is more or less a copy of the info he posted there as well....
...
...I think the resistor is a gold,black, purple, yellow. what ever that is in the color code... looks to ge a 1 watt resistor?
and the pot a 50kohm

Well, today I received my Map/Maf Enhancer and as soon as I open the box I began to take it apart. I have been building one based on the schematic that I got off the forum but as a backup I purchased one. I took the one I bought apart it was very simple to make I don’t have the schematic but I took pictures so everyone can make one. I am no electronic expert but this is as simple as its gets take a look.

Ok, now that you have looked at the pictures.  There is basically a switch,resistor,pentiometer,project box and some wire ( 2 leads and a bare ground).  Instructions:  Ater completion of your easy to make Sensor Enhancer. 1.  Hook up bare wire to ground or your vehicle body 2. Black wire will be your signal from your map sensor 3.  Red wire will be your signal from the Enhancer to computer.

Cowboy (Chris Tolly) tells me the POT is 50kohms !

this is from the Hydrogengenerator.cc web site "Scratch posted some pics of the Map/Maf inhanser he bought figureing anyone could make one!

pics to follow...

and the other 2 pics.... thats all the info I have on it.
hope it helps.

Thanks Bob and scratch1676 that helps. That sure looks simpler than what I got.

Here is the one I have parts for but yet to assemble.

Ahhh I like that one...its regulated !
...problem is ... what do they mean by a MAP sensor ? all these initials are less than informitive <GRIN>
  on the car which one is it ?... and whats even more important ...what does it do !?!
...
that looks like a good one to me to be hooking to the computer line...
seams like it would have a steady voltage output to the computer.. and I think that is what you want... but not real positive... you see they made these sensors to be variable for a reason... to adjust to the verying conditions and still put out the right mixture to the engine... when we stop the adjusting ability by changeing the sensor  how do you know the adjustment is RIGHT ?
.... parden me for being a bit skeptical, but it seams like a good way to go, but perhaps not the safest in all conditions, like a hot summer day,& driving too lean could be realy bad on the engine.
... if the sensor adjustment is done right you should have complete control of the fuel to the engine... this is fantastic for saving gas... but... you can fry your engine fairly easy if you don't have a way of telling what the adjustment is DOING to the fuel mix !
...
I've read some of the "Adjustment procedures" on some of the ones for sale on the web and they are a bit un-nerving to say the least....
like adjust the knob till the engine starts to stagger real bad and then adjust it back 1/4 turn and your all done...
which would take you to too lean and then richen it up a bit.. and it should be fine
... and technically once the engine is warmed up each time you drive it you should re-adjust it....for the best economy. 
   but lets face it ...most people will set it once and forget it ! and thats probably not the best way to get a long life out of your engine !
...
   I dunno if these things are going to help or hinder the system...  really !
although I'ed rather have control of the fuel than the computer, it is a risk I'm willing to take.... are you guys willing to do the same ?  because thats what these things will do
... drive along and bump the knob accidentally and not notice it and you could fry the engine !

Dang Bob!  That's Tolley!   There's an 'e' before the 'y'...  People even mess up my name on the internet now...     No worries, I'm used to it.  Well, my box is packed up and somewhere in the middle of the ocean, but as soon as I get it back I'll take pics.  I set mine up dual with the city/highway theory.  However, if we are able to introduce hydroxy in front of the MAF, the box isn't needed...  The only difference in my box is that there is a three position switch and another pot setup.  The switch give you 'bypass', 'highway', and 'city'.

HAHAHA Cowboy your Lucky I got the right name asoiaciated with the Handle there !
...
Ok TollEY ! gotcha ! hehehehehehehe
....
but whats your package doing in the middle of the pacific ? ain't it supposed to be on the truck ? or have you been off playing war games again and sent it by snail mail ? <GRIN>
...
all in all, I seriously think the "MATT Valve" is doing a very good job for me, no fancy electronics needed with it... just a garden hose and a on off ball valve for the waterhose
line... and some RTV silicone and make a by-pass around the MAP sensor... and adjust to where its TOO lean then back off a bit and make sure it smoothes out when the hydroxy unit is turned on... if it don't give it a bit less air...
....
 However I havn't driven my truck for about 2 months now and the Hydroxy unit is on the bench, and the truck is totally under a snow bank, so it ain't going anywhere !
but it WAS working real nicely....
