Re: Yaw Rate Chart

Thanks for this. I have set the acceleration data at 60Hz, but on your advice I will up it to 100Hz.
I was more concerned about validity of the acceleration readings once you start moving mostly sideways on the track.

Re: Yaw Rate Chart

I am digging out the venerable thread after a splendind morning sliding around on an icy AX track this morning. If there is a lot of drifting, handbrake U-turns involved, should I use GPS-based acceleration data to compute the yaw rate? I am using a 20hz GPS with a consistent 0.77 HDOP (3m accuracy?...

Re: CarPlay (iOS) / MirrorLink (Android)

We might wait for the carplay forever. In the meantime, there seem to be another solution, alas it is vehicle specific: https://developer.ford.com/pages/applink . I see the available interactions as quite promising - you could possibly even get by without OBD-2 or GPS link! The app could have access...

Re: HLT switches my diesel to OTTO

I am glad to report that the workaround works well.
Horsepower calculation still points to a surprisingly high figures, but it is more sane for sure now. Diesel stays as diesel now.

HLT switches my diesel to OTTO

When investigating surprisingly high PS readings of my Galaxy 2.0 tdci, I realised the car settings automatically switch from turbo diesel to OTTO. It must be coming from OBD2 handshake. Can it be ignored? What difference does the engine type make?

Re: Redrive 20Hz GPS receiver

That's what they answered when I asked via online form about Redrive compatibility with HLT!

A procedure for setting accessories' delays

Is there a "scientific" procedure of setting proper delays for accessories (OBD and internal GPS in my case?)? Assuming consistent OBD update rate and the fact that Harry probably tested the default internal GPS delay (1.5s) extensively, I see two options: 1. Analyse a lap or a performance...

Redrive 20Hz GPS receiver

I saw a new entrant to the GPS accesories world recently - http://redrive.it . https://redrive.it/wp-content/uploads/2013/06/rd1-1.png It boasts 20hz update rate, SD card, BTLE compatibility, external ant included. The firm claims to be in contact with Harry. Does it work with Laptimer already? If n...

Re: Track time/distance per car

While track events are added automatically to the timeline, it is not that easy to get a sum of the _track_ driving distance. For this you need to mannually multiply number of laps per particular track distance for each event. What I meant was a number in brackets added automatically in the heading,...

Re: Car launch not detected

Thank you. OBD update rate is 4-6Hz, resonably consistent. I guess the next thing to try is to disable OBD, or use GPS speed as primary (is there such option? I only saw this in video overlay...
