Hi David, these WRT videos are really interesting, Im soaking the info up like a sponge, thank you for taking the trouble to video this. Just to add something, you questioned the meaning of the TPS. I had to replace a faulty TPS on my MT09 Gen3 (common fault with new incremented part). Its basically a rotary variable resistor that physically mounts to the butterfly rotation shaft. The butterfly valve is on the right hand cylinder together with servo motor which is controlled by the ECU. So its just a sensor providing feedback to the ECU on actual butterfly valve angle (there are 2 signal channels for comparison I assume). I wrote the change up on the MT09 forum in case you want to look it up.
By the way I will buy the gen4 SP next year and will be on the island of Cyprus so derestricting the ECU by myself is an interesting option. I reached out to Two Wheel Dynoworks in the US but they wont flash an ECU from outside the US.
