Default replaced Power Transistor/igniter module - now car wont start, injectors stuck closed

During all this my friend accidentally, trying to help, installed a fuse into the ST slot so the MS blew Q5 transistor - ordered it from diyautotune & had it installed onto the board (originally the fuel pump wouldnt prime, it does now).

So I replaced the powerTR unit, I have spark, I have fuel prime & pressure, but the injectors arent opening & the pulsewidth & duty cycle for MS dont say anything even though it worked just fine before

I have attached a toothed wheel log & a datalog of cranking, why are my injectors not opening? Is this a megasquirt problem or a miata problem?

During cranking the board looks like this, the D14 & D16 (iirc) LED's stay on continuously, the middle LED doesn't turn on.




A step in the right direction or a few pointers would be nice, this car hasn't been driven in almost a month! =(
