Default high idle/flame out

Gotta say first..I love my JC BEE II KS. Since June, I've logged over 120 flights, and over 20 hours. Not a single problem.

I noticed the last few flights, that the idle seemed high, around 60k or so. Last flight went well. Landed and while spooling up after stopping, at about 70% throttle, the engine quit. (No smoke)......Last shutdown reason on the ECU.....SPEED LOW.

I went through and checked all the transmitter and ICS setting and reprogrammed the ICS to learn the transmitter.
Started the turbine. idled fine at 55k. Did the ecu learning procedure. Back down to idle......85,000. Wouldn't come down.
Any ideas??
Thanks,
Don

Don:

Couple of things. . .have you changed fuel lately, ECU battery fully charged and most importantly, have you been tracking the PW (pulse width ) of the fuel pump during operation. If PW is registering higher, you may have a fuel issue within the system. Can you check the delivery of the fuel pump? I would like to know how many ounces it is delivering in 5 seconds. Other than the obvious such as possible filter contamination, check the system. If possible, hook up an alternate source such as your taxi/over flow tank direct to the fuel pump and check results.

Let us know.
Eric

If possible, hook up a fresh "D" cell battery for the test.

I have requested a new fuel pump be sent to you. . .please check your email for my follow up .
