Thread: VVT Intake Exhaust Advance Retard vs Base Angle Input

    VVT Intake Exhaust Advance Retard vs Base Angle Input

    Using HP Tuners looking at E67 LE5 Variable Camshaft VVT settings, is the following diagram correct? Assume the cam is rotating clockwise; is '0' Full Retard Intake and Full Advance Exhaust? Where a number of '24' in relation to '0' would be '24' Advanced Intake and '24' Retarded Exhaust.

    '0' would be the number in the Base Angle barometric tables under the Variable Camshaft tab.

    Cobaltssoverbooster, I am looking for sources other than yourself because I already read some of your replies on this and I am triple checking. That was a little sarcastic, thanks for the info.

    I recommend you find the GM service manual that explains it, if you're looking for another source.
