Looks like a crappy connection or scaling's off. Probably not a connection issue with the MoTeC data reading ok. I would check the input for the brake bar in the SCHD config.
Three choices: brake position, inline acceleration and brake pressure. Should be brake pressure and scaled to the maximum psi you see on the MoTeC data.
Odd that you get temps on the SmartyCam, as that is not usually transmitted through the VCS_CompoundFull_Transmit template from the dash to the Bridge.
That car is a BEAST! Love that vMax!

With that said, I looked at RaceStudio3 and confirmed I am using the brake pressure input scaled at 0-100 bar as can be seen below. Looking at I2 data for the second lap in the video I posted, you can see the brake pressure graph as the lower line in the I2 picture below. The peak brake pressure is 68.04 bar. You can see that the brake pressure curve is very smooth while the brake pressure in the video is very jumpy / peaky and in no way representative of the actual pressure depicted in I2. I'm a bit stumped here.
Regarding the temperature overlay, both oil and water temps are on CAN bus and are transmitted to the SmartyCam via the ECU bridge. I also have transmission temp and fuel pressure / temp transmitted and displayed on the Motec dash but I don't think there is any way to display that on the SmartyCam. I'm thinking of swapping over to the Motec V2 camera but I don't think I could display that data either. Overall the SmartyCam has worked very well but I would like to get the brake pressure sorted.
