Neither do i . I'm using a starlane digi race stealth - something or other . it's funny when you get things like attatched pic:

That's just telling you you can backoff the pace a little bit and still win the race... :P

I use the LT-6000 and really like it. Works as advertised and the data logging is quite good.

Down sides: is only accurate to about +/- 0.2, but honestly not like us club racers are trying to qualify for F1.

Also, the software and interface aren't the easiest to use.

But for $400 and gives you real time lap times in the car plus green/red projected times on your lap your doing, it is a great tool.

Most phones don't have high speed GPS sensors. So to get more acurate you should have a dedicated GPS device capturing at 10 hertz. But phone apps are ok as long as you aren't looking for too much accuracy.

Are there any dedicated gps lap timers that take video as well? That's why I like this app, but worried about launching my iPhone out into the back paddock of Wakefield though!

V Box and similar can incorporate video as well as having a whole lot of useful driving and data analysis features. Performance Box is cheaper, not sure what it's features are but it is too big to mount on the steering wheel like the LT-6000 will.

How do users find units like the LT-6000 with a built in GPS in a tin top car? No problem with GPS signal interference requiring a remote mounted sensor?

I mount it on the front window that is what the recommend. Occasionally you'll get a signal wander that causes the location to move about 10m but timing still works fine.

I don't think you'd want it on the steering wheel as that would take your line of sight too far away from the track.

If you mean all the gauges etc then it's just a program that you load the qstarz data file into. Their are dozens of gauge sets available (even clusters from common sports cars) and you can move them around or edit them till your heart is content.

The Dashware software is pre-configured to detect the data file that is made by the Qstarz so you simply import the file into Dashware then drag whatever gauges you want onto your video screen and it works.

Awesome! Is it fussy about what type of video files?

Also, how bright is the screen in the car when it brings up split times etc.? I took my brother's car out to Wakefield yesterday which had an Aim dash, and in the sunlight I couldn't see a thing!

Also, how does it work out where you are on the track when you add the video file? Have you found it to be accurate?

Just can't work out how the video and data logging lines up accurately without any data from the video file.

    • Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!
    • To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules
    • So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket
    • As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year. 
    • I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
