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

Graphics can be small images or drawn from rectangles, circles, triangles or lines. Shapes can be filled or unfilled. I usually have an outlines version and then smaller filled version. That way when off you make the fill black or dull and its doesn't need to redraw the outline.    Anyone could design a layout and any stock can bus data could be used to update the graphics.  If you have aftermarket ecu then you can customise what can bus data they send or use a built in dash preset.   links to some examples to show what data aftermarket ecus send out. Link ecu: https://www.akao.co.uk/manuals/Link G4+ Manual/device_specific_can_informatio.htm haltech: https://support.haltech.com/portal/en/kb/articles/haltech-can-ecu-broadcast-protocol emotion: https://help.emtronaustralia.com.au/emtune/PredefinedCANTransmitPacket2.html   This is the case and screen except in black. Only a small 4mm hole gets drilled above the USB port for wiring   There are a few version of this and you don't always know what you'll get. All have wifi with the same screen and case. The ultra is the basic single core 80MHz without bluetooth and without can bus controller builtin. cheapest USD$6. official price USD$25 The pro is dual core 240Mhz with bluetooth with builtin can bus controller. cheapest USD$12   Adding generic boards for power and can bus cost another USD$5-7. The pro has touch sensor built in but the ultra has 1 spare pin after can bus so can have a board added that enables touch. That way tapping on the top can cycle the display through different screens.
