JPI fuel flow not working.

[heygeronimo]

So We installed the jpi fuel flow in my apache about a year ago. Maybe have 3 hours flight time on it. After sitting for repairs the last 8 months the right engine only reads fuel flow at idle. When i throttle up the left engine flow increases wih throttle however the right engine fuel flow goes no higher than it was wjth the engine at idle. Any clues?
