I use JJ pump only for bench run so far.

Yes I manually control the starter because of semi auto ECU. Now I also suspect the weak starter because the engine can be motoring only by starter at max. 16K rmp, is it not enough? Normally I engage the starter until 31K rmp. Do you know the detail of full auto start such as fuel on speed, starter disengagement speed and their related PW value? thanks so much!

Start fuel ramp is setting at 002 in ECU. I disassembled the engine last night and no abnormal findings except that rear bearing inner race discolors due to high temp. What can I do to rescue my engine?
