Thanks Bibendum  

Definately worth doing, $1k for a healthier car is worth it. If youre game you can get a tactrix cable, romraider and DIY. You can get decent gains with a laptop, wideband and a bit of time (a lot of time) spent tweaking the fuelling, timing and boost maps.

Seems since 2024 Michelin has bee sharing its RIFD tech with other vendors. links to FAQ:  https://rfid.michelin.com/what-is-rfid/ https://www.continental-tires.com/continental-for-business/services-and-solutions/rfid/   The data is pretty limited, mostly around a few numbers the vendor can look up and get the size and specs of the tire along with their internal data like production date etc. manufacturer company assigned ID model is zero to 17 trillion serial is zero to 274 billion   Looks like there maybe multiple tags for some companies as they had their own larger visible ones previously. The new ones are 38mm long and under 2mm in diameter and work from 1-5m from the tire. datasheet: https://rfid.michelin.com/wp-content/uploads/2024/07/dataSheet-TireTag-muRata.pdf   Members of the RFID group other than Michelin Continental Bridgestone Goodyear Bridgestone JATMA which is most japanese brands: https://www.jatma.or.jp/english/about/member.html
