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.

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.
