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.
