OK, for those who want to learn, here is the root cause and the fix:
The pickup installations can be slight diffrent from one bike to another.
the pickup pulse widths have variations from bike to bike. At high RPM, like >= 10k; the pulse width become very small, like 100 micro seconds (us); which is 1/10000 second. A small variation can cause big difference at that super short "period". Our old calibrations ignore the smaller than 100us pulses. Which caused the misfire.
We now change the threshold to 50us, half of the old one, meaning it can theoretically handle 20k-RPM pulses. This is the fix.
For those who want to convert the carb bike with any ECU, the first thing to deal is the pickup signal. And that is the most challenge part of the EFI software.
