Log sensors with key on, but not trying to start.

Coolant temp ambient temp outside ?

Aren't evo8's 560cc ?

Increase injector size until it actually wants to fire.

You swapped ecus ?

Can you take the ECU out and take pictures of the components... especially the middle area where the big capacitors are ?

I had something similar years and years ago with my first DSM.  It would run, but like crap.  TONS of black smoke out of the back.  Was a burned trace on the back of the board.  I jumped the burnt trace with rosencore, never had an issue after that.

Another thing is, are you sure one of the injectors is not stuck open?
