    hahaha yea i figured out it was actually a 1jzge

    nah i knew someone would ask and ive been working on cars for long enough for me to notice this but hey

    there was a weird issue between wiring of my old boost cont which ran off the injector signal and the new one. So basically one of the injector outputs was running eventually back to +12v. Why this only happened when it was just coming on boost i have NFI.

    Atleast its fixed now and i can stop scratching my head
