  1. Logging / graph crank & cam sensor signals (scope)

    Is there a way to log crank & cam sensor signals with HPT? Looked around & haven't found anything. Want to graph the 2 signals and watch the correlation/ alignment of them.

    This is correct. Its a 3 wire hall effect VSS on 5v. GM uses a sine wave pulse on 12v.

    You're correct. Never set the ECT vs IAT temp to enable CL. Had it at 284. my bad

    Aside question, wouldn't the O2 & trim readings act/ record the same in open vs close just not have nay affect?

    Unless I'm missing something, I think it is set to closed loop. LTFT are not enable as I am tring to focus on the STFTs. That make sense?

    STFT are oppposite of each other and seem to be doing a criss cross pattern. At times Bank 2 STFT flat lines at -13.3%. O2 readings don't seem to following each otherr either.
