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,

wings back on my Velo hoping to restart after my EC2's round robin to
Tracy <g


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.
