i.e. just a log of tps/rpm/power/vac/bsfc/anything else?

that would be much easier to process in a script to sort it into a bfc-style chart.
the log files are massive. um im not sure how to send it over. they record about 20 different parameters per line and about 10 of those lines per second.

yes but this is the measurement of throttle and not accelerator pedal angle and yes this car is equipped with drive-by-wire.
