Yes, you can log the TPS and injector duty cycle.
TPS, I hooked mine up near the ecu pink wire with a black trace marker. If you want to pick it up at the sensor, you want the yellow wire.
The injectors fire with a grey wire with different trace markers. White, Blk, Yellow, or red.
I monitor the Gear Position Sensor Pink wire at the ECU and sensor
I need to hook up the Speedometer on mine but it is the pink wire coming off of it.
I'd suggest fuel pressure as well.
Add RPM and the built in Pressure sensor for boost and you are already running out of channels to log.
