PPI Typhoon

Since my chip so far has no rhyme or reason, here's an example if I come up with an Ultimate interface:
TheObiJuan said:dan would you and some of the other great minds here be able to produce one similar to that?
TheObiJuan said:say i have an ultimate for fuel control and boost control not enabled.
and i have a blitz sbcid for boost control.
would that display be dynamic, where the boost value would increase and decrease as i set it, or is it just outputing what the ultimate tells it to.
All that would take is a pressure transducer hooked up to a 555, which varies pulse width. That frequency is measured by the chip, which translates it from a table inside the chip to a digital reading. It's certainly possible, and that might be an option after I get the first one out.

canadian said:ron had a stand alone box on his truck at kc2k that i got to see work. iirc, there was a big display and by pushing one of the buttons it would cycle between the values he was grabbing from the aldl. all self-contained, just plug into the aldl. last i heard it was either time or problems getting all the parts in bulk that stopped a mass production of it.
now, what would be cool here is:
* el display
* ability to reverse the letters so that you could put it on the dash and use
it like a heads up display. i know there's something like this out there.
* self contained power supply (maybe a 9V battery). i'm not a fan of having
to plug shit in all over the truck 'cause it's ugly.
* ability to record runs. i think ron was planning on sending the output to a
32k rom and a serial connector on the back to download it to a pc.
* ability to program the display from a pc (ie: i want to have a, b, and c
displayed, then when i click the button i want d, e, and f displayed.
i'd be willing to chip in some time to help with that last one if possible. just my 2 cents, but that's what i think would be cool.
now if you wanted to get real freaky, pipe the output in NTSC format so you can hook up one of those 6" LCD's that are always on eBay to make a "digital dash" that you can mount on the steering column.

its ideal to grab the 12v from somewhere on the truck instead of having a battery for multiple reasons..
running off the sensors themselves is kind of dangerous especially when your dealing with a o2 sensor that deals in fractions of a volt, its probably much better to grab off the output of the ecm.
if anyone decides to mass produce a product as such, and needs another hand, id be will to put whatever free time I have into such a design.. hell I could probably use it as my senior design project![]()
