Hi Joe,

FFl and FFH are the two types in the engine data frame for a Fuel Flow
Function - but my notes says not used by the EM2.  So not certain what it
means, it possible it could be some value that correlates to fuel flow - but
I don't see how it could relate to any specific injectors since the EC2
don't know which injectors you have.  So perhaps that is why it is not used
- but just a guess on my part.

At the end of each engine data frame the EC2 will send an end of command
byte = FF.

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
