I'm puzzling over fuel flow calibration. I had it pretty close (when on
controller A; on B it is way off, and I'm thinking it can't work on B); but
then we did the injector snubber update, and it was reading way too high. So
I followed the manual and increased FFCAL; and it then read nonsensically
high. So I set it too a number lower than I started with; and it is still
reading higher than it did to start. I must be doing something wrong.
Recently found that it is possible to set the FFCAL value to more than 255 but 255 is the highest valid setting (it is a 1 byte value). If 255 is not high enough, you need to set the Fuel Flow Coarse adjust value higher (#18). If you have not had the EM2 updated since the snubber change, you will not have this coarse adjust value in the EM2. That is why the EM2 and EC2 must be updated at the same time.
