TPMS on C127?

[Stephen Dean]

12mm reamer to the rescue?

So the IZZE Racing TPMS Sensors have an advantage in that they do not have a inbuilt valve stem so you can use the stems that suit the rims.

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?

I have used these briefly.
They were a resolution of 0.7 psi, and was accurate to a known pressure gauge I trust.

These seem to have a better resolution.

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.

Ah, great. I get my car back in a week or two, then I'm planning on putting the sensors in. Fingers crossed they fit the wheel.

(Thanks for all of your help by the way, we're nearing the end) haha

As far as this part goes, same with my BBS wheels. We ended up drilling the wheels out and everything worked perfectly.
