Default N54 PMI no fire, meth pump? - 12-19-2019, 01:59 AM

I have study PMI 3 months and try some setup on it.
But still got problem cant fix.
N54 twin turbo FBO
PI with BMS PI controller for meth
6*750cc PI injectors
SNOW meth system handle meth pump

When all install, I log first and it looks OK. (220 PSI pump at this time)
after some run, I saw "meth" grow high in log file. I though that could be weak pump cause.
So I put new max 300PSI SNOW pump in. then I got this log.
After that I log many times. all trims high and I check everything looks fine. I guess the injectors didnt fire any more.

what is the problem? how to fix it?

Thx a lot
