    Default Can you make curve charts using scantool?

    Hi,
    Does anybody know how you could go about making curve charts using the data from scantool?

    Say, if I wanted to have a curve charts showing engine torque versus RPM. how would i get the logged data so I could make a chart?

    Cheers,

    You can log GM.TRQENG and SAE.RPM...

    GM.TRQENG is the PCM's calculation of engine torque based on MAF/VE and the spark tables... it's an estimation and it may or may not be correct.
