Joe and Ed,

Although Tracy's list indicates the FFL and FFH data now at the end of the
list, I could not get my data collection program to work unless I shortened
the length of the data string received.  It appeared as if that data was
never transmitted by the updated EC2.

Steve is correct, Joe.

Apparently Tracy has put Battery voltage VBATL and VBATH in the positions
that FFL and FFH used to occupy in the string and have moved FFL and FFH to
the end of the string.  Since I don't use either in my EFISM unit, I never
noticed the change until Steve pointed it out.

VBATL EQU 0x11A
VBATH EQU 0x11B

At the end of the string Tracy now has move the fuel flow factors

FFL   EQU 0x12D
FFH EQU 0X12E

The FF data has been eliminated from my EC2's with recent updates so if you
plan on keeping your EC2 updated, the investment in interpreting this data
may not be very productive.

I am working on checking all engine instrument calibrations. For those who
may have done some work interfacing to the EC2's serial data, what does the
FF (FFL/FFH - Bytes 0x2E & 0x2F) represent?  Any insight to conversion
formulas is appreciated.

Thanks,
Joe
