While not totally worthless I think logging TPS position is not needed in most applications. My car is injected and the TPS works for the ECU for accel enrichment and idle reference only. From a log point its usually easy to look at other fields and say "Yep I was flooring it" lol. I don't know how many channels the Innovate has but if you find yourseld out of room for things to log I would drop the TPS.
