my next "spare time" project....

[Marc Swanson]

Not sure what triggered the thought in my head today but I came up with an
interesting spare time (yeah right...) software project relating to adapting
EFI to my 4ktq.

I'm really interested in direct fire ignition coupled with EFI to rid the
car of the entire CIS system and computer for good.. but of course nobody
makes such a beast as of yet for a 5 cylinder engine (and even if it is
available it will cost an arm and a leg plus one other appendage of your
choice).  Then it occured to me:  Why not build a software program that will
run on linux and utilize an A/D card or two to send and receive the
necessary bits of data to run the injectors and listen to the engine
sensors??

Naturally if I dove into building the thing in hardware right off the bat
I'd never finish the project so I think for starters I'm going to play with
building a "virtual machine" to simulate the running of an engine with the
ability to modify operating perameters while the simulation is running.  If
I can prove the concept works virtually (I don't see why not...) then I'll
think about working it into real hardware.  A/D converters run plenty fast
enough to control the "slow" speed of an engine even at redline... and I
really can't think of a single limitation that would make this an impossible
project...  And hey, who can really say "My car runs on Linux!" ? ;-)

Anyone care to shoot down my project/theory?
