Well shift lights just need assembling and will have 3 spare 40 led bars 20mm square by 22cm long I will make another few 16 bar smaller ones 12mm square by 15cm with a hide away box for the brains. I have 2 cases for the old school flashlight ones which I want to experiment with. There is also another dinosaur in bright lime green that could be used. I got 2 initially but they sent pale green knock off one instead of blue.   The Bluetooth TPMS boards should arrive next week so I can make TPMS to can bus for logging. They should support most Bluetooth sensors so you can buy cheap ones and have multiple sets of wheels with sensors. It will log which ones it sees on startup. Since sensors sleep until moving it should only log the current wheels.   The main audio project got a little larger than planned and now does a whole bunch of new things. Also adding language support so far English, but Spanish is a work in progress and Japanese should also be supported. Mostly that around how the say numbers. English has unique up to 20 eg we say eighteen not 10 and 8. Spanish is unique to 30, but has “y” between larger numbers which all needs to be coded.   https://www.jaycar.co.nz/super-large-seven-segment-display/p/ZD1850   While waiting for parts YouTube recommended a few rally videos. One of which had a nice gear indicator mounted to the side of the dash cluster. So 40 hours later a 70mm tall (58mm for actual LEDs) 8 segment display for canbus is almost ready to order parts to see what actually fits. The controller with same wifi setup fits exactly behind the display and has M3 mounts inneach corner.   Just thinking about adding a few solder points for a light sensor for night dimming incase the car doesn’t have canbus. You can make it show 1-10 by sending it a can message or a byte where each of the 8 bits turns on a single led segment.    

after looking at aerodynamics videos and Subaru related content the algorithm surfaced this. Its English overdubbed which can be a bit annoying when there are two people talk over each other. https://www.youtube.com/@stion-tube5753/videos    

After a few days thinking about this it could be interesting for reading the tire model and setting the ecu map or mode.   fit semi slicks and have ecu go into track mode with higher boost etc.  combined with outside, tire temp or under car temp sensor you could know where I the tire compound is operating.   or at the least log what tire was on the car when it was started.   the tag is tiny so I suspect you’d need a coil in each wheel well to power them up. Still if you have those IR tire sensor fitted already it could be a simple add on.    since this is close to ID badge cloning there are already a lot of projects and documentation around. Security conference already have a few people with long range badge closers. Car thieves also have a lot of tech for reading key fobs to start cars and that is all the same principles.

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.
