Observations

1) Connecting the gauges Misc In to either the AFM or the TPS causes the engine to hunt at idle and stall at junctions. Suggestions - wire in line with 10k resistor. Result = Car no longer hunts at idle, however in Megatune, Misc in gauge does not react appropriately, nothing logged to log file for Misc.

2) Pressing the button on the Gauge to cycle display causes momentary drop in revs and lambda spike. See Attached.
