Holley 4Di Download File Format

Wed Dec 30 05:06:58 GMT 1998

I looked at one, but your guess is as good as mine.  Call up Holley. 
They were cooperative when I talked to them.  I asked them how to read
the data coming from the RS232 line so that I could write a data
acquisition program, and they emailed a copy of their data acquisition
program.  That saved me the time I would have spent writing it.

I looked at one and it seems to a whole bunch of hex values separated by
spaces.  There are also some strange characters in it.

If you can't get the info, you might want to set a map to all zeros and
look at the result.  Then, start entering values and note the change in
the .M16 file.
