As I indicated on my recent post my fuel flow indication to skyview is erratic. On start it seems to indicate a reasonable f/f, however it's all over the chart after only a few minutes. It doesn't seem to indicate high, just what I think is normal for the power setting all the way down to zero. I haven't done a continuity check, but all of the wiring from the red cube to the ems box appears to be in good condition, no chaffing, or acute bends and they run through braided lume(sp). Is the "Flow Scan 201" compatible with the Dynon ems? I have one and if it is compatible I'd replace the Red Cube with it to confirm that the red cube is either good or bad.
