TPMS ID's
 

Will the BRZ/ FR-S ECU hold more than 1 set of TPMS ID's? Recently picked up some new wheels that I'm planning on swapping back and forth and would like to not have to re-program it each time.

It only holds one set of IDs, unfortunately needs to be reprogrammed each time. Make sure you write down what is currently stored before inputting new ones.

I have the solution for you - a set of the Schrader "EZ-Sensor" TPMS valves ([ame="http://www.amazon.com/Schrader-33000-EZ-Sensor-Programmable-TPMS/dp/B007NK2NDC/ref=sr_1_1?ie=UTF8&qid=1448760647&sr=8-1&keywords=schrader+ez-sensor"]Amazon.com: Schrader 33000 EZ-Sensor Programmable TPMS - 315 MHz: Automotive[/ame]).

They are programmable, so rather than program your ECU to recognize another TMPS set every time you swap, you clone the TPMS valves that you have. I just got 4 of these for my winter wheels/tires; once I found a shop with the equipment and know-how to program them, and was all set. Be forewarned that idiot "techs" at many a tire shop told me what I was trying to do was impossible and that no such thing exists.

I also swapped out the rubber snap-in valve stems they came with for some aluminum stems ([ame="http://www.amazon.com/Schrader-34000-Aluminum-Clamp-Sensor/dp/B007NK2L66/ref=pd_bxgy_263_img_2?ie=UTF8&refRID=10NA7A9APD14D HWGQPHJ"]Amazon.com: Schrader 34000 Aluminum Clamp-in Style Valve for TPMS Snap-in Sensor: Automotive[/ame]) that worked great on my RPF1s.
