2jz trigger 2 cam polarity in G4+ Posted November 18, 2018 · Report reply On 11/15/2018 at 10:20 PM, Adamw said: In your 2nd triggerscope picture (bottom) the cam sensor is correct polarity but the crank sensor is wrong in both pics. So it looks like you need to swap the +/- wires on the crank sensor. In the 2nd pic the cam sensor is outputing very low voltage so you may also need to set the trig 2 arming threshold quite low in the zero and 1000RPM cells. try 0.3V@0rpm and 0.5V@1000RPM. Adam, mad genius you are. Not just on my issues but all the problem and issues you catch is simply invaluable. Had her on a true mustang dyno yesterday 420/412 with a small hx35 on gate pressure - 20 psi and ran out of injectors. tuning on e90 with flex tune - it did 377 hp pump gas. very happy! Great experience with Link thus far! excited for the next season, Thanks again!
