Just to get into the spirit of this list lately - which has radically 
changed to the dark side in the last year - why don't you just look it 
up?????? 

Not to be a smart ass, but thats what the collective wisdom of this 
group of dweebshit told me when I asked about a rumored knock detector 
signal processor.  And heaven help you if you haven't kept up with every 
post from the lord and master concerning the mythical ION and EGOR, you 
are told to blow it out your arse if you would like info - or even just 
a guide on where to get the info.

Don't you know there are literally hundreds of sites dealing with PICs 
and it's cousin STAMPs.  the PIC producer Microchip will actually send 
you a foot high stack of those obsolete and antiquated things called 
books that detail everything you ever wanted to know and more.  Got full 
drawings, tech specs, thousands of lines of existing code to do much 
stuff, and even a CD-rom with more stuff - all for the astronomical 
price of ----- tadaaaa  ------  FREE !!!!

And by following the links you can find anything you want - including 
wireless radio transmitters and receivors should you chose to telemeter 
your data off-board, clocks, electric motor controllers etc.

Try www.microchip.com or www.parallaxinc.com (makers of Stamps).  From 
there follow links.  Parallax has mailing lists and FUNCTIONAL archives 
(subtle hint with a sledge hammer) that deal with these devices.  MIT 
has a mailing list that deals with them.  Anyone who cares can run down 
in a matter of minutes more data, applications and help than they can 
use in a lifetime.  A heck of a lot of it deals with automotive 
applications. 

The programming language is simplified to bare essentials.  The chips 
integrate counters, processors, pulse width modulators and even A/D's 
but don't worry - nobody on this list will even consider making their 
private domain pet project compatible with PICs.  And since the chips 
communicate not by wire trace bus's - but a simple serial logic - you 
don't need to be a PCB layout genius to use them.

And why PICs when people start thinking simple.  Part of simple is the 
availablity of non-dweebshit or self-appointed guru data and parts. PICs 
and stamps meet this nicely.

There is a lurker (or was quite recently) who has actually built for the 
SAE competition a complete fly by wire engine management system included 
fuel, spark and throttle that resides on a USB controller chip - with 
the help of a couple of custom reprogramable custom asics.  But he did 
it SIMPLE because he understood what he needed to do.  Note that this 
was a controller - not a "micro processor" - not a power pc chip running 
Linux - but a simple ass controller - and it is working tonight, not 
still in the sixth month of labor after several years.

Most of the EFI projects are way over-engineered. KISS will keep 
recurring.  Non Dweebshit rules - Whatever WORKS is BEST - no exception.  
Simple is better.  Simple does not mean Trivial.

Several months ago, some of us had a splinter discussion concerning 
using a PIC or a STAMP and a USB controller as the basis of an engine 
management system.  Then we would use a PC or a laptop to do high order 
stuff like optimization algoriths.  It never went public on this list 
because not everybody choses to follow the orthdoxoly of complicating 
shitting detroit style and we really didn't care to hear all the 
screaming flamers who didn't like our ideas.  

Now back to our regularly scheduled disection of GM and mythical 
projects that only a selected few will ever be privileged to view the 
results of. 

I now resume the position between to pnuematic side hammers to pound new 
ideas into the ears.

Habeneros - not just for breakfast anymore!!
