Ok weird that this is not set by default as I did a clean install of non video 4 version.

When I load my traces I get the following msg: Error Report To use the GPS/accelerometer tuning option, GPS speed accuracy is required this is currently disabled in the variable manager. What does this mean? My dl1 is 20hz with the gyro. I defaulted to the basic setup today as I was getting the same...

Thanks for the help guys. Pretty sure its not the connection as it has worked fine that way on a couple of occasions with manual triggering, even at the same circuit. Both my unsuccessful logging days were at Silverstone, so Maxx you may be onto something with that bridge comment although I don't th...

The killer for me however is that I had a Porsche supercup driver put some laps in in my car and I really wanted those traces. He only did 3 laps so very u...

Getting pretty annoyed by this now as it seems I can't use the unit without a laptop at the circuit just to check its not doing something stupid.

Tried autostart/stop for the first time yesterday. It didn't go well. I have 49 files of between 500kb and 900kb. No full laps of the circuit at all Settings are as follows : Auto start conditions: > 200 Auto stop conditions: > 200 Pre trigger: 1 min Post trigger: 1 min Now my understanding is that ...
