What do you mean by "monitor engine rpm, spoof throttle position sensor?" Can you be a little more specific? I want to make sure we're on the same page
Throttle position sends a voltage (typicaly 0-5v) to the ecu. voltage from the TPS monitored during throttle blips. Then matching voltage sent on TPS signal wire to the ECU. See if the ECU responds by closing injectors. If the effect is throttle position related (rather than RPM) the rpm should fluctuate with open/closeloop switch. (this is most likely a silly idea as I was mostly just thinking of ideas without filtering them much)

Re mpguino. If you are using it for injector testing purposes there is no need to get VSS signal.
