My riding buddy bought the CHIGEE AIO-5 lite for his Yamaha

Has anyone here investigated this product for the C400GT / X?


My C400GT has the TFT display and I use the BMW Connected app for navigation and music. It also tracks my rides - mileage, weather, speed, RPM….etc

They also have an add on module which integrates into the bike allowing us to use the wonderwheel ti control the device.


Will using this CHIGEE AIO-5 render the Connected app and TFT useless?

Thoughts?

I decided to order the CHIGEE AIO-5 Lite from Indiegogo since they offered the InDemand packages…..about a 20% cost savings from the CHIGEE site. CHIGEE does offer a 15% discount.

I’ve been riding with an inexpensive Motorola Android phone worth about $150 with no SIM card. The phone connects to my travel hotspot for data. The Motorola is an inexpensive disposable phone and can easily be replaced.

I do carry my iPhone 15 Pro while riding but not mounted on the bike because I’m afraid the vibrations may damage the sensitive camera mechanism.

Riding for me is complicated carrying 3 devices! It gets more complicated when I need to change the default volume settings on my SENA 50S HK edition. This requires me to pair & unpair to my iPhone 15 Pro to update settings.

I also found the audio from my SENA 50S was substantially better when connected directly to my iPhone vs the bike.

Purchasing the CHIGEE will only require me to carry my iPhone 15 Pro. My SENA will connect directly to my iPhone instead of the bike….better audio.

The CHIGEE will give me Apple CarPlay or Android if I decide to switch platforms. I did order the CGRC-CAN module which allows me use the wonderwheel to navigate the Apple CarPlay.

Fingers crossed this setup works and exceeds my expectations. I will start the install process tomorrow and keep you guys posted.

I missed this when you first posted. Thank you very much for this. The timing is excellent for me as I am planning a trip to Canada on my NC. I'll start looking at this more closely and would be super interested to learn if it is easy to transfer the main processing unit from bike to bike. BSD and cameras are important to me. I really appreciate this post! Off to the gym...I think I may be a little distracted at work today!
 
I’ve wired the Chigee to my C400GT for a quick test.

I now have Apple CarPlay!!

Next steps….
- connect my SENA 50S HK to iPhone 15 Pro
- test Spotify for audio test
- pair iPhone to bike for conflicts with Connected app
- install TPMS
- install CGRC-CAN - BMW integration module

Here’s a photo of the BMW integration module as well as the TPMS sensors.

The TPMS sensors are the same diameter as a dime vs a quarter.

The Chigee unit is designed to be permanently mounted on a bike.

I’ve done some testing and I’m liking it especially the voice commands - Siri and Google.

I’ve enjoyed the BMW Connected app to track my rides and weather along with other features such as displaying the speed limit. The recently released RTTI was helpful but Google maps has a similar feature.

I’m considering Scenic as a replacement.

I’ll provide a comprehensive write up tomorrow.

Those are external TPMS sensors, correct? If so, have you screwed on the front one, and confirmed that it won't hit a brake caliper when the wheel is rotated? If so, this is most puzzling to me.

Hey Bill,

The valve stem TPMS sensors do not interfere with the brake calipers.

In fact the new Chigee sensors are smaller in contrast to my previous TPMS setup.

Hey, first of all, thanks very much for the info.

Second, what model-year of the C 400 GT do you have?

I have to track down my notes from when I first checked this out, on my '22 model. Regardless of my notes and measurements then, I remember actually TRYING this out, on my '22, with my then-new FOBO sensors. I even bought a tire-rotating gizmo -- https://www.harborfreight.com/motorcycle-wheel-cleaning-stand-98800.html -- to make it easier for me to spin the wheel. (I think I posted about this before, but, whatever, it turns out that that's a nice device for making it easier to clean the front wheel.)

And it certainly didn't work: the FOBO sensor hit the caliper, and I wound up just putting one of the new sensors on the back wheel, and keeping the other one in its box on the shelf.

I haven't tried this yet on the new ('23) bike, but I just took some measurements, and it still looks mighty close. Here's what I just did (after getting that spare FOBO off the shelf, along with a spare valve stem):

1) Measured the distance from the bottom of the threads to the top of the threads: 0.948"

2024-04-05_17-14-26.webp

2) Screwed on the FOBO, and measured the distance from the bottom of the threads to the top of the FOBO: 0.407"

2024-04-05_17-13-34.webp

3) Thus, subtracting, the FOBO sensor extends 0.541" beyond the end of the threads.

4) Attempted to measure the minimum distance between the top end of the threads of the valve stem on the '23 C 400 GT and the side of the caliper, which I think occurs at about this point in the wheel rotation:

2024-04-05_17-42-51.webp

5) Unfortunately, I couldn't find a way to square up my measuring caliper, using its in-between measuring end. Instead, I stuck as many segments of a folding ruler as I could get in there. Three segments fit, with a little play left over. I had to estimate this play when I measured that width, so this measurement is, alas, the least accurate: about 0.534"

2024-04-05_17-44-22.webp

(I have a pack of feeler gauges, from the days when I adjusted valves myself on some bikes, but the entire pack is only about 0.4" thick. Otherwise, that would've been a much more accurate way of determining this distance. Hey, maybe I can combine some feeler gauges with the ruler segments ...)

You'll note that this in-between distance, 0.534", is slightly less than the distance, 0.541", that the sensor extends beyond the threads. Even if my estimate is off a little, it's still very tight.

I'd be interested in the distance that the Chigee sensors extend beyond the outermost thread. If it isn't practical for you to measure this, I can always try to get this info from Chigee -- heck, I'll try anyway.

It's certainly possible that the Chigee sensors are shorter, top to bottom, once screwed in place, than the FOBO sensors (which is sort of a shame, because I've grown fond of the FOBOs, their quality, the quality of the FOBO phone app, etc.).

Maybe I'll roll out that Harbor Freight dolly tomorrow, and confirm my sort of theoretical results with an actual test; I haven't attempted that a second time, and maybe something changed in this area, between the '22 and '23 models.

Thanks very much for the info. Now to look into the Chigee sensors ...
 
I just found the Chigee sensors -- at least, I think I found them -- at https://www.chigee.com/products/tire-pressure. They're listed there as being 14.8mm tall, which is c. 0.583".

Screenshot 2024-04-05 at 6.52.44 PM.webp

This seems to be a little shorter than the FOBO, depending on how you figure the measurements:

FOBO_BIKE_2_Image_PS001162916.webp

Of course, what I'd really like to know is something that neither of these pictures shows: the distance that a sensor extends beyond the valve stem once the sensor is screwed in place. That is, those height figures are interesting, but not very meaningful all by themselves -- they don't take into account how many threads of the valve stem will fit inside the sensor.
 
Update: Communication With Chigee

Last night, I filled out a web form at Chigee's site, and asked them about the MFP0019 sensors. And they responded via email me impressively quickly. Here's the conversation:


Me:

Regarding your MFP0019 External Tire Pressure Sensor, your page https://www.chigee.com/products/tire-pressure lists the height of the sensor as 14.8mm. What I'd like to know is how far the top of the sensor is, beyond the end of the valve-stem threads, ONCE THE SENSOR IS SCREWED ON. That is, after screwing the sensor in place, the sensor will extend LESS than 14.8mm beyond the end of the valve stem, because some of the threads of the valve stem will be INSIDE the sensor.

I'd like to know this information because I own a 2023 BMW C 400 GT scooter. BMW has the valve stems on this scooter sideways, in what you might call a spoke of the wheel. On the front wheel, there is very limited clearance between the end of the valve stem and the side of one of the front brake calipers (see attached picture).

Thank you very much for any help you can give me here.



Chigee:

We regret to inform you that the 2023 BMW C400gt is not compatible with the MFP0019 External Tire Pressure Sensor.

Therefore, you cannot install the MFP0019 External Tire Pressure Sensor on your 2023 BMW C400gt.

We sincerely apologize for any inconvenience this may cause.

If you have any further questions or if there's anything else we can assist you with, please feel free to let us know.

Best regards,

Chigee

So, should I take them at their word?

@byee : Sorry to bother you again, but just to clarify:

1) Have you actually installed a sensor on the front valve stem, and then rotated the wheel a revolution or two?

2) Are you using the MFP0019 sensors, or is there some other TPMS sensor model that Chigee sells -- perhaps only in conjunction with the AIO-5? I'm definitely confused, because you showed two different sensor sizes -- the dime and quarter -- earlier, so I'm beginning to think that we're talking about different sensors.

3) You noted earlier that "In fact the new Chigee sensors are smaller in contrast to my previous TPMS setup." Can you tell me about your prior setup, please?

4) We are talking about a C 400 GT, right?
 
@wspollack

Good afternoon Bill,

No need to apologize for asking questions!

I have a 2019 C400GT. There's about 5mm of brake pad left in the center of the left side pad. I used a 3D printed brake pad measuring gauge. The 5mm is the closest.

The measurements provided will be from the wheel surface where the valve stems threads into vs measuring the threads. Here you go!

total length of the stem 13.34mm or 0.525"​
total length with Chigee TPMS cap 24.13mm or 0.949"​

I did measure the distance from the inside edge of the front caliper to the top of the TPMS cap 0.72mm or 0.028" of clearance currently wit 35K kms. I am due for a brake job sometime this season. I am certain the TPMS cap will strike the brake caliper with a new pads installed. Any ideas how thick new pads are..........measure your new replacement bike since its still new??

The thought of the TPMS sensors hitting the brake calipers has never even crossed my mind when I installed the Cyclops TPMS setup back in Sept 2020 when I had 11K kms on the bike. The total length of the stem with the Cyclops TPMS cap is 25.0mm or 0.984"

Would you happen to know if there are different length valve stems available which mount onto our C400GT wheels to increase the clearance?

I hope the above information helps!

Barry

Barry, thank you VERY much for the info, and your time and effort.

First off, regarding the thickness of new (715 miles) brake pads, er, um, I have an APPROXIMATE figure for you. That is, I don't feel comfortable removing them -- unless it's extremely easy, someone (or, say, the shop manual) can guide me through it, and I can't possibly screw up taking them out and putting them back in -- so I only have a rough number for you.

So I tried to align my caliper with the pads in situ (and there's some parallax error in the pic, but not really, when I was doing this live a few minutes ago):

2024-04-06_16-49-03.JPG

And then, turning my caliper around, without moving the measurement:

2024-04-06_16-49-10.JPG

So I make the thickness of a new pad at roughly 0.306" (7.77mm), or possibly, looking at the pic, maybe a tad more.

Let's move on to your question: "Would you happen to know if there are different length valve stems available which mount onto our C400GT wheels to increase the clearance?"

Funny you should ask about that. Just like the freakin oddball location that BMW employs for the valve stems, they, too, are oddballs, not your garden-variety stems.

I wanted to examine one up close and personal, without removing one from the bike, which would have let the air out, possibly breaking the tire bead, and possibly ruining some thread-locker. So in August 2022, less than a month after I took delivery of my first C 400 GT, I ordered one from Max (email screen grab):

Screenshot 2024-04-06 at 5.02.00 PM.png

And then I looked at it closely, and took a gob of measurements. For example, here's on pic from Aug. 2022:

2022-08-11_17-03-54.JPG

So you can see that this is not an ordinary valve stem. The green-coated threads screw into the corresponding tapped area of the "spoke" (or whatever you want to call it), and there's no nut on the inside, etc. So you can't "get behind" that stem, so to speak. (And I'm pretty familiar with ordinary valve stems, because over 25 years I've had shops replace stems, when changing tires for me, with assorted angled or T-valve stems that I've provided.)

So, no, this is one-off territory, no non-Beemer variations would work, IMO.

(On one visit to Max for something, I actually asked the workshop manager if they would be willing to drill through the center of the front wheel rim, so I could add a regular valve stem, for TPMS purposes. He told me: nope (and I can understand their position). I have thought about asking an indie shop to do this, but even that idea is sort of a problem, because the center of the rim is angled, not flat, and I'm not sure that a good seal would be possible. Nevertheless, I bought a pair of new high quality straight valve stems, of the 8.3mm variety, in case I ever go this route. (Most bikes use an 11.3mm rim hole, but a good portion use the smaller size; I decided that if I'm going to have a hole drilled -- in the center of the rim, the way every other manufacturer does it -- I might as well keep it as small as possible.)

Back to the stock valve. I also peered inside, and took some more measurements. I was wondering whether I could dremel off some threads, in order to lessen the external height of the valve stem. The problem there is that the standard valve core already takes up all the room in there, i.e., is essentially seated at the bottom of the area. So cutting a few threads off the external threads would also entail cutting through the valve core. And I'm not aware of any extra-short valve cores, although I haven't really looked.

It was about that point that I gave up, mounted the FOBO sensor on the rear wheel's valve stem, and put the other sensor on the shelf.

@mzflorida renewed my interest in this whole TPMS thing a week or two ago, when he showed me a TFT screenshot of TPMS readings, by someone who has apparently unlocked (hacked?) this capability. I have no idea how the sensors are mounted; they're apparently internal sensors, but they must have nothing at all to do with the stock valve stems, because, as I mentioned, there's no threads behind those stock stems -- they just screw into the spoke. So they must be mounted in some fashion inside the rims. And the whole thing requires that this gentleman remotely update the bike's software. If this is legit, the whole thing is just too weird for me.

Now, to get really far afield, another -- expensive! -- possibility is to get new wheels. I think the front wheel on the Voge SR4 Max 350 -- like the C 400 GT, manufactured by Loncin -- is designed for the same size discs (265mm, per https://www.1000ps.de/motorradvergleich-voge-sr4-max-350-abs-2023-vs-bmw-c-400-gt-2021-150107, vs. 10.4", per https://www.bmwmotorcycles.com/en/m...gt/technicaldata.html#/section-technical-data ).

If you're unfamiliar with that scoot and have 12 minutes:


Most importantly for this discussion: the Voge has normally placed valve stems (see the pic at https://chinamotorworld.com/voge-sr4-max-proved-to-be-a-reliable-touring-scooter/ ). They're angled, but they could easily be replaced by my all-time favorites, the T-valves from FOBO -- https://my-fobo.com/accessories -- which I used on my second Big Burgman (an '08 model, owned from '16 - '22):

2022-06-11_17-47-11.JPG

But, yeah, I think I'm losing my tenuous grip on reality here. Probably just drilling into the center of the front rim would work best.

That's all I got.

I did. It's the videos of how Phad modifies the C400Gt to activate TPMS. They will not play through a link posted here though, so it was useless.

Well, let me give this a shot.

As it turns out, Phad put up a YouTube video on this two days ago:


(If the video above isn't public for viewing on forums, for instance, click on the "Watch on YouTube" and it should work. This is what you have to do to watch the Scooteria video that I included in post 13, above.)

I just added the first comment to that YT video, asking Phad for some clarifications on the parts (i.e., sensors) and procedures involved, and whether this might be able to be done by a BMW dealership. We'll see if he responds to my comment in a day or two. If you want to read my comment, click on "YouTube" in the lower right, as the video starts playing, and you'll be taken to the actual YT page. There, you can just scroll down the page to see my comment (and click on "Read more" to see the entire text).

There's also an earlier TikTok video Phad made:

www.tiktok.com/@phad_motorrad/video/7337627865678155026

Let me post this now, and see what happens ...

[Note that I had to do some Edit work on the TT video: I just had to remove the H T T P S : / / at the beginning, making it a plain ol' hyperlink to click on, as opposed to something that the forum thinks is an embedded video.]

Interestingly, I just ordered a stem as well to monkey around with. I'm going to see if I can machine about 0.5mm to 0.75mm off the back side on my lathe. This should help add some clearance for the valve stem mounted TPMS sensor for the front wheel. Ordered on the weekend and should arrive mid week.

I'm hoping I can take back to local BMW dealership to install for me. Definitely keep you posted.

I did reach out to Phad on Facebook a month or so back. You need to add another module to the C400 by 'frankensteining' in as there is no feature/option connector. The module in Canada is about $450...definitely less in the USA.

I'm pretty comfortable with the bikes electrical but hesitant to 'frankenstein' it in. Once added, I'm quite sure you can use MOTOSCAN to enable the option.

I am curious if our wheels are threaded for the BMW RDC's.

Yeah, @mzflorida explained it to me a week or so ago, via an email, re the frankensteining. That is something I probably wouldn't be interested in, especially already having one C 400 GT replaced by BMW last year -- I wouldn't want to give corporate an excuse to not honor my new warranty. That's why I asked in my YT comment whether Phad knew whether a dealership could do all this, which would of course maintain the warranty.

I still don't really grasp why a dealership couldn't do this, if the sensors are a BMW part, and they certainly have the equipment to talk to and update the bike's software. Is it as simple as they have not officially provided for this as an option -- just didn't think about, or something like that -- even though it can technically be performed?

And, yeah, I wonder how the sensors would get mounted (which is also something I alluded to in my YT comment). If there is provision for mounting BMW's (or anyone's) "RDC" built inside of the rims, then wouldn't it seem as if BMW DID think about the option? I mean, why else would they do that kind of extra machining of the wheels? As far as I know, no other bike in their line-up uses those wheels. The whole thing is very weird.

And as I've ranted before, this whole issue is one of my two major gripes about the bike, i.e., not having made TPMS either stock or an option, as they do on almost all of their other bikes. (The other major gripe I have is the lack of cruise control, given the moniker of Grand Tourer, and especially given that the bike has throttle-by-wire, i.e., no need to have servos controlling physical cables -- the whole thing could be done with software.)
