I'm experiencing two issues first the steering wheel speed is roughly half of what the actual vehicle speed is. The speed data on the video overlay from the SmartyCam is correct. I checked the PDM and SW4 channels and both were set to MPH. I changed the PDM channel to KPH as Ben Jacobs suggested and will try that to see if it resolve it. I think it is double converting the wheel speed signal.
The second issue is that the lap timer will show the entire session as one full lap instead of breaking it up after passing the start/finish location. I verified good GPS signal and the track is loaded in the SmartyCam. I called Radical in the UK and they suggested having the track loaded in all the modules (PDM, SmartyCam, and SW4) they told me that the steering wheel has some to do with recording and deciphering lap data. I will try that and retest next month to see if it took care of both issues. I'm confident in the speedometer issue being fixed. The laptimer I have less confidence.
