Subject: PC interface for Tracy's EFI

Would anybody like to store the "tune" on
a PC
and be able to look at a graphic of the
whole table as it changed
with RPM and MAP? In other words a
graphic 3D over view
of the fuel injector table. Great for
understanding what is
going on.
Handy for trouble shooting when the
injectors are staged.

Sure i am interested

I too would love this.  I think someone at the Texas
Rotary Roundup a
 couple of months ago had something he was using, but it
was not yet
 ready for "prime time".  There MAY have been some
discussion about
 making it available.  I know I would like it
especially IF it were not
 outside my electronic skill set to be able to use. IIRC, he had a
 serial interface cable that would link to the PC and then
some software
 which would provide data.
I understand Tracy's desire to be able to program
everything w/o a PC,
 especially in the air AND based on when it was first
developed, however,
 with $200.00 netbook computers and so much initial
development on the
 ground, I would love to be able to "see" more of what I am
doing via a
 netbook/notebook 'puter.  FWIW.
All the best,

Paul,

You are correct, Ed's instrument is not an addition to
Tracy's it is
INSTEAD of.  IIRC, he developed it when Tracy did not
have one.  I spoke
to Ed about it at the Texas Roundup and asked about using
it too, but he
assured me it was not needed if I had Tracy's unit. It is more
colorful, but is redundant.

The other unit I was speaking of is different and works
thorough a
serial interface to a PC and I believe allows data logging
from the EC2
(which is an add on in the newer EC3) and lets you see
more/most/all (?)
of the MAP table.

Do you have a web site address on it?

Chris,

Steve Bose (sp?) had the data logger he was using with Tracy's controller.
He did a demo at the Rotary Roundup earlier this year.

No charge for the software, just make your own interface box (couple
of IC's).

Tom

Anybody have Steve's email address?
