TPMS on C127?

[13cobra]

What's the most economical way of getting TPMS on a C127?

[David Ferguson]

I'm currently installing a Trailbrake TPMS system for a customer. Since it uses production parts, the price seems reasonable.

Interesting!

So it's $225/sensor? Then they just communicate via CAN with the Motec and can have a page in the display made to show the data?

Also, are you currently doing the internal or external sensors?

[David Ferguson]

No, the complete 4-wheel system is $225 with the receiver and 4 internal or external sensors. Look at the pictures to see all the parts. The internal sensors are $32 each. It sends Pressure, Airtemp, internal battery voltage and a leak alarm from each wheel at 5 hz, on a 1Mbit CAN bus.

My customer bought the TPMS unlimited with the base system + 4 internal sensors (8 total) for $401:

Ah, I was sold at $1800 haha

I would much prefer the internal sensors. Do I need to buy the training tool as well? I would assume so, but you didn't mention your client did.

[David Ferguson]

No, they came pre-programmed two sensors already labeled for each corner of the car.

Did you have any issue, or foresee any issue integrating into the Motec Dash Logger?

[David Ferguson]

I wound not have suggested it if I did not think it would work with your dash / logger.

Here is the CAN Comm Template I created from the documentation. You may need to change the channels to suit your installations (not sure you will have all the channels I used). And the sensor voltage is in .1V units, but the channel I chose only has whole units, so I just left it multiplied by 10 (so 31 means 3.1V).

A 5Hz update rate is better than the 1hz that they mention in the specs. How accurate are the pressures read by the sensors compared to an accurate tyre gauge David?

[David Ferguson]

Since I don't have it really working, I can't confirm, the protocol claims to send data every 200ms, but perhaps that's one wheel every 200ms, so closer to 1 HZ.

Our project just came to a stop a few minutes ago. The internal sensors don't fit the valve-stem opening in the BBS wheels my customer is using. Wheels are about 8.5mm, and the sensor needs something like 11.5mm.
