WOW! Awesome info! thank you.

So, the intercepter idea is the way to go? I take it that the PIC is the device that will do that?

HI THERE:
The pic or a basic stamp controller. Both are easy to program via you laptop or home computer. Try looking up a magizine titled NUTS and BOLTS.. Theres normally a page or two each edition to some pic or basic stamp project. Yoy can program a basic stamp by using the WINDOWS VISUAL BASIC PROGRAM... most of the commands are in basic which is cool place to start for newbies. EXAMPLE:
input a:
if a=< 100 then print
A simple basic instruction!

If interested in programming pic microcontrollers using basic language, have a look at Proton Development Suite, by Crownhill. http://www.crownhill.co.uk, They do a free Lite version of their programming software. Also have a look at Pickit programmer. Well worth checking out.

Note that their compiler will accept in-line assembler language as well as basic commands.

Take a look at this little gizmo , anyone willing to throw $500.00 at it to see if it works Big Grin

Edited to add Vid of the unit linked into to his ECU

Well great minds think alike! I like where this guy has taken this device. It is fully programmable with plenty of additional options. Pretty sweet really. He took it about 5 times farther than I would have but bang for the buck and the ability to upgrade the controller software using a smart card really makes this one a winner. Although it is 500 bucks I think you really get what your paying for. Just the amount of work that went into this unit is astounding if your an electronics techie. Now if it works as advertised I figure with normal driving habits of most folks with the addition of HHO to your vehicle it would easily pay for itself in fuel savings with todays gas prices in 6 months. If we were back to 4 bucks a gallon it would most likely be about half the time.

I am positive that this is the right track to be on. Leave the ECU to think all is well and we control the environment of parameters. I really like the fact that for a bit more you can get control and status from the ECU via the OBD2 Interface.

Nice find!

Make my day

Here's a vid of a guy that bought one , he seems convinced Smile

IMHO , the programmable smart card kicks butt , set to vehicle speed , even the O2 offset is automatically reduced when slowing to a stop.


Man , I want one Big Grin

RE: RPM controls the PWM ?? I have an idea..
I love that unit and I am saving my pennies till I can get one. The website shows the next generation of the unit I guess. I have asked questions hoping that they will be answered about it being able to also adjust the IAT. Although when I get this unit I might convert my MAPSE to adjust the IAT since it also is only adding resistance to the circuit it should work for that too.

I'm still drooling :P

The magazine is called "Nuts and Volts" - I knew what you meant though..

As an addition to the microcontroller debate, I've used the BASIC Stamp and it is a wonderful little chip. Parallax ( http://www.parallax.com ) makes it. They cost about $70 a piece.

A chip I would use, and have used, is the SX chip also made by Parallax. It has lot more horsepower that the Stamp and is much cheaper - $2.79 a piece. They also make a protoboard for $10 that has the power supply and small area to solder on your project, this includes the chip. The best part is the compiler is free and they have an excellent forum for help - free also.

COOL! I like the in line assemler module. I DON'T THINK I'VE WRITTEN IN BASIC in 30 years. MIKE

YOUR RIGHT! NUTS and VOLTS. THANKS FOR THE INFO. I see that some of the other adventurers have already found a device that works in a similar way . Still a bit pricey and I'M quite sure I don't need a display to show me the status . But certainly the VMU is a work of art and indeed shows that the idea of digtal control verse analog is a cool concept. Looking at all of the pars generated to feed the ecu is the most accurate way of regulating the fuel mixture. The cost of the chips you suggested , does seem to make for a cheaper alternative . Would be easy for me to cad this into a design, along with the other hardware needed as an all in one type gizmo and still keep the cost factor down. There are quite a few low cost multimeters on the market that can be used as the system monitor, that also measures temp ,voltage and current etc. and could be intergrated by virtue of test points from the gizmo. ONCE optimized for a particular car , I, for one ,don't care about looking at a visual. One of the things, I have a question about ,is the operation of the VMU, the fact that there seems to be a touch senstive display that allows you to change the relative sensor outputs manuelly makes me think that the device functions in a manner that allows you to view the O2 ,MAP, MAF, etc , but functions in manner that requires you to manuelly make adjustments based upon the display data in order to optimize. Not sure if its a smart device, that is auto compensating or just a monitor with a digitally controlled output array. THANKS MIKE
