adjusted the tps, redid the timing.



now it cuts out at ariound 5k and 8psi.



is there anyway to check my FCD with my multimeter to make sure it works?

same thing



fcd shows more voltage at 8psi.



but i guess i ruled out the injectors, its cutting at 8psi now i guess.



theres no way to multimeter the fcd to test it?

safc shows more voltage at 8psi without the fcd. 70% instead of 40-50ish

its not boost cut, unplugged the boost sensor and theres the cut, right smack dab at 3800. i read it forces the secondaries on at that rpm when the sensor isnt there or is capped off.



so, my injectors definitely arent coming on.



so unless some other sensor or something can make them not come on, its the ecu?
