broke another clip today testing a vin change/immobilizer delete for another customer..
first time I've used my pop4 scanner, and first with a blue laser, it did a good job getting the shape, not a printable part by any means but enough to model around the scan in fusion 360
details here.

prop/driveshaft seal replaced. I've done a couple of these I figure I should document it. age + 150mph tears them. I believe there's a seal on the front of these bearings too but you can rvt the outside front if they leak from there. there's NO way to get that seal out, these are press fit together at the factory.
this one looks like a mess, I preformed emergency repack & rvt at the VIR to get me through the weekend...
What started out as a cross balance app turned into a lot more, I went way down the rabbit hole
Reverse engineered my proform scales Bluetooth and integrated reading the scales live into the app
Added a handheld esp32 pyrometer that syncs the 12 values to the phone via ble this part is open source on GitHub here https://github.com/MrBlahhhh/PyroTC
Added Tesla tpms to get psi and temp via ble to track cold and hot temps
Added my packing lists with an uncheck all that follows my normal workflow
Designed and printed a handheld case for the pyrometer collector, stl will be on github with the esp32 code once I finish the final print.
Now I'm learning how to publish a android app to the app store...

Not sure if anything like this exists for Android . I couldn't find anything other than websites
What started as me not wanting to go to a website to do the corner balance math quickly escalated into let's track the tire camber and my temperature spread and hot PSI at the track in a log format..
I used my phone to scan a couple weeks ago, now it wont connect to the scanner with android app version 3.0.2 I am able to connect to the lightbridge
My backup phone works fine on version 3.0.1
I came up with two designs to try to at the track in my Ls3 car one uses two pass with a small gyroid on top. The other one has a swirl flap at the bottom and a bigger gyroid before the baffled lid
I'll try both of them on track at the next event. I was getting between a quarter and a half a quart in the catch can every 20 minutes
Had to plug the valve cover pcv ports they get covered with oil in the corners and it just blows all the oil into the lines
new PB for me, car is a 135i with a L92 out of a escalade
it's a bit of a drift missile if I'm not judicious with the gas pedal
It started out a little wet but dried out nicely and was a really fun weekend. I did manage to get used to the car and set a new PB of 2:02.95.
I took one of my instructor friends out in what I think was blue or instructor run group, vid below.
Car ran great, all the swap teething seems to be resolved except for a better air oil separator and I need to relocate the oil pressure sensor off off the engine itself
24 hours print, it locks into the stock box lower section. Fully open rear port to the brake master cylinder area which is open to the top. I had someone ask for a inverted scoop for that too so that'll be a future scan/print project.
I have the box on cults, same link as the previous 3 designs that are not open to the back

I thought I was done messing with this design but I might add a a third port for daisy chaining if I'm not using a can hub
It has an internal TPU gasket in the DTM port that I've posted before here
H2c printer, left nozzle does the tpu and right does the HTPA-cf
