Overview
John is tired of a 'dumb' factory TPMS that only says a tire is low, not which one or at what PSI. On the Dasaita Android head unit, a downloadable TPMS app shows each corner; the right-rear is low, so he pumps it up with the Audew compressor. Installing a cap takes two tools — one to hold the stem, and one to tighten — and you want it snug, then locked, not overtightened. He isn't very worried about theft: without the matching wireless transmitter and an Android head unit, a stolen cap isn't useful, and it's hard to remove without the tools (it just spins). After the fill, the app reads 29.9 PSI and the low-pressure warning is gone. He recommends this kind of setup because you never know when you'll pick up a nail, and you can set low and high alerts — he uses 24.7 PSI as a low reminder — but you should still check pressure after getting gas. The description's first Amazon link is the Audew tire pump; the TPMS itself is listed on AliExpress for Dasaita units, with a USB version on iDoing, plus AliExpress and Seicane links for the kind of head unit on camera.

Step by step
- 1
See which corner is low▶ 0:00
The TPMS app on the Android head unit shows each tire. In this clip the right-rear is low, so that's the one to fill.
- 2
Add air▶ 0:19
He pumps the low tire up with the Audew compressor (and notes that tire will need to be changed eventually).
- 3
Two-tool cap install, don't overtighten▶ 0:35
One tool holds the stem, the other tightens the cap. Get it snug, then lock it — don't screw it too tight. He's not very worried about theft: without the wireless transmitter and a head unit, a stolen cap isn't useful, and it's hard to unscrew without the tools (it just rotates as a unit).

29.9 PSI and custom alerts▶ 1:28
The app now reads 29.9 PSI and the low-pressure warning is gone. He recommends this because you never know when you'll run over a nail, and you can set low and high alerts — he uses 24.7 PSI as a low reminder. Still check the pressure after getting gas.
Wiring notes
- No dash wiring: the caps are external, and a wireless transmitter talks to a TPMS app on the Android head unit.
- The description also mentions a USB-style TPMS option from iDoing if you want that version instead of the wireless cap set shown here.

0:00Here's the Android head unit and of course you have the TPMS.
0:05This is an app that you can download and once you're into this interface you can tell which
0:10tire is low.
0:12In my case it's going to be the bottom right, so all we have to do is pump it up.
0:17So let's just get right into that.
0:19So we're definitely going to have to change that out eventually.
0:34There you go.
0:35And then to install this again, we have these two tools.
0:39One to hold the rocker, this thing, and then you have this actual tool right here.
0:44Now you don't want this screw in too tight.
0:47So try to get it snug.
0:49advice is to get it snug and then kind of lock it like this. Can people steal this?
0:56Honestly if they do steal it they literally can't do anything because they
1:01or in this case the wireless transmitter to have information on their Android head unit.
1:08So what are the chances of having an Android head unit and the USB thing to do it?
1:14The wireless transmitter?
1:15Not likely so if they steal it then they steal it but it's kind of hard to take it without
1:21the tools.
1:22You can see it's just rotating the whole thing and I'm trying to unscrew it.
1:26Alright there you guys have it right there.
1:28You can see now it says 29.9 and there's no longer says low tire pressure so everything's
1:30This is 29.9 and it's no longer says low tire pressure so everything's super easy to get to go.
1:37Now do I recommend something like this?
1:40Yes because it makes my life a lot easier especially because you never know when you run over a
1:45nail.
1:46You can set alerts such as if it ever is low tire pressure
1:51or too much pressure you can mess with the values.
1:54Now I set it to 24.7, if it's needing like that,
1:58just remind this, hey, tire is low.
2:01But I recommend you guys to also check
2:03the tire pressure after getting gas or something like that.
2:08Other than that, that concludes it.
2:12Thank thank you guys for watching, peace.
