Karting again in Chiba 09/04/26

I still haven't found my way to TC2000 since the last race. I haven't been avoiding it... just worked out that way. I was supposed to go on the 25th but it was a very wet day so I canceled and ended up going karting on the 26th instead.

Karting is such a blast particularly when you get a nice handling kart which just does what you want it do do. Even it wild oversteer moments if you are quick enough it comes right back although you do lose speed that way :-)

Anyway, thought this was a decent photo and it does show my new helmet paint job which I haven't blogged about yet. I'll take another photo of it when I put the darker visor on.

The good news is weather for the rest of the week and the beginning of next week is looking fine as I'm due to hit TC2000 on the 2nd, 4th and 5th :-)

Adding an RPM input to TraqMate

The TraqMate unit provides a wire whose sole purpose in life is to hook into a tachometer feed and tell you how many RPMs you are doing. By hooking in RPMs, tire sizes, gear ratios etc you also get some other info like what gear you are in, what HP/Torque your car is producing. It also makes for more entertaining videos as the rpm needle should finally move!

After asking around and gathering the required info on how to connect that wire to the car, I finally got together with my good friend The FeatherKing and hooked it in.

It all turned out to be quite easy after we had TraqMate hooked up to the cars power/ground. The key is the following diagram which shows where to connect the TraqMate wire to. The target wire is marked TA and is color coded Yellow/Black.

The PCM is on the roadster is located under the airbox and once you get the airbox off (and disconnect the battery etc), you see something like the following. The red arrow shows the 2nd wire from the left on the top row where we hooked into.

Once we'd tapped the wire and tested it to the TraqMate unit by setting the car as a 1 cylinder car in the TraqMate car setup, it all worked and we needed to find a way through the firewall from the engine bay into the cabin where the TraqMate unit is kept. This also turned out to be quite easy and we found a nice path using the same access hole which my gauges were using. The arrow below shows the place.
Path through firewall.

Finding where this hole came out in the cabin was another thing... I forgot to take a photo of this part but its basically deep in the passenger footwell and higher up than you expect.

The following photo shows where I have both the TraqMate Sensor Unit and ChaseCam stored under the passengers seat. It works out quite well with some heavy duty velcro sticking them both down.

I'm getting really fond of the ChaseCam unit even though I am officially still testing it. The camera mounts nice and low and the units mic is out of the wind unlike when I had my conventional handy-cam up there on the rollbar.

All I have to do now is hit the track and get some proper footage! Next track day is May 2nd and of course the Party Race is coming up on May 5th. Wish me luck!

Creating a video with TraqMate

I've been wanting to upload a TraqMate video of March 10th at Fuji for sometime now but I thought it would be fun to show a little demo of how easy it is using the TraqMate/Chasecam combination to pull out a video of your best lap of a certain session. So here it is...



Two things wrong with this video of course... One is that the video capture program that I used to capture the video from my desktop doesn't actually show the video that the TraqMate software actually shows for some reason. It does show the other videos though which is a bit wierd. But anyway... The second thing is that I was too lazy to do sound :-)

So - once you do all that, you basically end up with your video file... It's so easy. No more editing or not much anyway depending on what you want to do. The video I made in that video is this one... Its not actually my fastest lap but it's not so slow either :-) I'm quite the happy camper with my purchase!



Enjoy!
