Hi guys yesterday I had a flame out and the gsu read low rpm has anybody know the cause for this thanx

A Low RPM shut down is usually the point at which the ECU gave up the fight to keep the engine running. Covers a multitude of sins, particularly when no other specific reason can be given, most often the result of air in the fuel lines or no fuel reaching the engine.

Need more of the story to go any further: in the air, on the ground, white smoke trail or not, visible air in the lines, UAT empty, throttle setting, etc., are all clues.

Hi there was no smoke trail , uat was full and there was no air in the lines ,it happen I was about just under half throttle and powered up that's when it flamed out

White smoke trail is usually positive evidence of air in the lines. With no smoke and a full UAT you're looking at a failure to deliver fuel to the engine. So: pump, solenoid, filter, blockage....??You might look under Info and see what the last pump off voltage was which may or may not tell us anything. I'd pull the fuel line from the engine and see if the pump is working. Under Test Functions, use the Purge Fuel System to run the pump like you're purging the lines except use the right arrow to run the pump voltage up over 2 volts or so. You're looking for a failed/stuck pump, failed solenoid or other blockage. It's also possible the problem is in the ECU.
