Re: Procedure for calibrating sensor delays ?

OK Thanks.... so for an external GPS (XGPS160), I need to increase that delay, not the "consumer-grade" delay, correct?

What is the default OBD delay, I lost track?

Thanks again...

Re: Procedure for calibrating sensor delays ?

Thanks Harry - So, with OBD being ahead of GPS... it is GPS that is delayed, or OBD is early.... Then do I REDUCE the OBD delay from 1.8 to 0.0 since it is 2 seconds early ???

Re: Procedure for calibrating sensor delays ?

Harry - A quick and possible 'dumb' question -- How do we interpret the use of meaning of the sensor delays? Is the delay parameter added to, or subtracted from the timestamp? For example, I'm finding my OBD Speed peaks and valleys are consistently ahead of (earlier than) the GPS speed peaks and val...

Re: Procedure for calibrating sensor delays ?

Thanks Harry... that is generally what I've done in the past... i.e. to get OBD and GPS to line up. I've calibrated OBD absolute speed to GPS separately, using a long duration steady 60 mph run on highway. (My track tires are smaller, and thus I have a 0.97 factor there). I've had a lot of experienc...

Re: Enhanced VBO export

For me, actual "Wheel Speed" from OBD is the most critical. Gear is next... temps are a nice to have.

Procedure for calibrating sensor delays ?

Does anyone have a good procedure for calibrating sensors delays amongst acceleration, GPS and OBD? If this has been addressed, please point me to the post on this? Prior to the inclusion of "sensor fusion" logic in v22, I had adjusted my OBD sensor delay to 1.8 secs, after several events ...

Re: Enhanced VBO export

If you can also integrate any/all OBD data channels (when they exist for the laps being exported), that would be very helpful. From my previous testing, CT doesn't care what the channels are named; they are simply a stream of data points aligned to the GPS position. I was able to manually add chann...

Re: Displaying lap times while recording

Great and thanks. My previous method was to go into the video view and hit the red record circle in the upper corner to begin video recording while waiting on the grid. Laptimer would record a long incomplete "lap" and then record all other laps normally passing over the S/F line. The draw...

Re: Displaying lap times while recording

Thanks Harry - With this "manual recording"... I assume Laptimer will still trigger laps passing over S/F... correct? (I've not used this method before)

Re: Displaying lap times while recording

Harry - Does this also work on Android now as well? More specifically... in pits can I start video recording then return to timer view, in order to catch my pit exit and initial out lap?
