Hi all,
I first time join your forum. But need a help from your experiences.
I got a jj-1200 with a start problem. Some start attempts with semi auto ECU were failed due to high EGT over 800 degrees. Engine disassembly is good. JJ support told me increase the max. temps to allow rotor runs up to idle. I think this is the worst means and suspect ECU setting should be the cause.
In my ECU the start point is auto+2 and start ramp is 002, are them ok?
What is the best rmp at which fuel come on? every time fuel in fuel line can't go into the engine until PW value approach to 70 because starter make the rotor runs up to 14K rmp within 2s while fuel pressure seems not overcome the air pressure at this point. I have to disengage the starter intermittently to allow fuel in and speed not drop too much. But the time taken by this process make higher PW value and surge fuel goes into CC.
Waiting for your good idea!
