The engine was run again with the new fuel values (153). The mixture knob was at about -24% for a smooth running idle, so the fuel values need to be decreased some again.
The Dynon tachometer pulses have been tried at 1,2 & 3 pulses per revolution. Ross advises most use 2 PPR and the EMS220 tach signal yellow wire. The resolution and update display of the Dynon seems to have higher resolution and quicker response than the SDS programmer.
The #4 EGT has been higher than the other cylinders at idle but seems to level off at 1200 RPM.
The Hall Effect ammeter settings need to be checked as the display was showing a negative value whereas the VPX was showing up to 18 Amps.
Occasionally, the primary Dynon Display has blacked out after initial boot up. Cycling the master switch causes it to reboot and function.
The A ECU is powered through the VPX and will be moved to the Essential buss.
Scott Fish had visited this weekend and we admired each others work. He's installing an Avidyne IFD540.
Both trim springs have been installed. I'd previously broken the paddle board pitch trim spring while testing it so made a new one with a different layup schedule. The roll trim servo is a $34 servo off Amazon.
