Topic: I built my first adjustable MAP sensor, and some other junk

[dexetr30]

I'm definitely interested in getting one of these from you. It'll be nice to have as I add stuff to my ride.

I got the first board done using the laser printer method last night.  I've still got some 'ironing' out to do (that's actually funny to me because I use an iron to transfer the toner to the PCB... haha), but it seems to work nicely.  I have to get my hands on a band saw to cut the board into 3 pieces so I can etch the other 2 circuits for the 2 extra boxes I'll be making; but the first one looks good.  I'll update when I get that done.

You are so the man. Good work.

All right. As I said, the laser printer transfer method worked better than I expected.  I have another hitch now though... The copper clad board I'm transferring the circuits to is just large enough to fit three of them (which is convenient since I'm building three of these) but I don't have a scroll saw any more :(  I'm looking around for a cheap crappy one from like Harbor Tool or something.  It's just got to cut copper clad boards, so a hot butter knife is almost good enough...   I'm looking at about 70 bones or so to get a cheap one shipped to me.  When I get it I'll cut this baby up and etch it.  Then I can solder the junk on and test it finally.  I've got the MAP adjuster done and tested for some time now, but I see it as pretty pointless to install it until I have a way of watching what it's doing to my jeeps Air Fuel ratio, so there it sits on the coffee table... watching... waiting... wondering when I'll touch it again... poor little guy :(

Can you rough it out with a coping saw then clean it up with a file.

[midnightcwby]

I have neither here with me.  I'm just going to suck it up and get the saw.  I'll need it for other projects later anyway.  I friggin should have brought my dad's old one with me.  It'll cost more to ship it than it's worth now.  Oh well.

Any updates??  I'm dying to know!

I'm going to provide the circuit diagram.  I've got a Volvo 740 turbo I'm playing with right now, and I still am missing one damn part to finish making the air fuel ratio gauge.  I will, however, get around to it sooner or later because this box will also help provide adjustment of the fuel mixture if one wants to run off of Ethanol instead of gasoline.  It will prove even more usefull than I thought when I started making it.  I just don't have a ton of time working at Intel.
