ECU7

[Al Lipper]

Steve,
	I'll try to answer your questions as best as I can.  Sensor setups are
entirely user-definable.  The program source code is available to you, so it
is not just a matter of changing data in tables - you can actually change
the way the data is used.  In fact, you can re-assign inputs or add new
sensors if you like (perhaps you might want an intake air temp. or knock
sensor).  There are a total of 8 analog inputs, though only 5 are used at
the moment (the other 3 are available on the connector for whatever you
like).  Currently used sensor inputs are: RPM, MAP, oxygen, coolant temp.,
TPS and volts.  ECU7 is currently set up to fire up to 4 batches of
injectors (though this can be expanded by adding more drivers).  Since you
may modify the program, you can set the timing and sequence of these
injectors as you see fit.  For data aquisition, it has a serial PC
interface.  I have mine setup to continually output operational parameters
for whatever aspect I'm working on and I capture these is a file for later
review (or plotting in Excel).  If you wanted the unit to capture data
internally, it has 128K of RAM (though only 64K is addressable without
modification), of which about 6K is currently used - the remainder is
available for whatever you want.  Incidentally, the RAM is battery backed
and will retain its data for about 5 years without external power.  Overall,
ECU7 has been designed with expansion and flexibility in mind.  If someone
wanted to eliminate features later, in order to reduce size or cost, that is
easy to do, but for the moment, all features we thought could reasonably be
used have been implemented.

We are currently devoting considerable time to the development of the ECU7
system, and would be happy to share knowledge (and gain from your
experiences) if you decide to persue the project.


Best wishes,


	Al
