@lucas010888 haha no. But your balls are 💪

@sotsstuff33 I couldn't tell you for Racebox sorry. The PID for brake pressure is 0x 21 41 Then there is an equation that is used to convert the reading to percentage brake pressure. You should be able to find some reference material on various 86/BRZ forums though.

@@craigline4760 I have not. Just this particular tyre

Lucas many thanks as there is not much data locally in them at all

@craigline4760 if it helps, the SP-01R did grip well but nothing above the RE71RS (80TW vs "200"TW). The SP-01R was reasonably predictable, however, 2 push laps and they fell off a cliff in terms of grip. Just overheated. And they wear really quick, so bang for buck wasn't quite there for me to recommend/use again.

Slightly different camera mount, but the track does have some bumps. It's a nice fun layout.

Cheers 😀 This is true, without exceeding the limit are you ever driving on it? Haha There were actual clean laps (not shown - cause who wants to see that)

Overlay is added in app, by RaceChrono Pro. I add the footage to my phone, then align the time of the footage with the data, then the app exports the final footage

Camera was overheating so didn't capture any laps driven in anger. I've just made public footage of the Switchback during passenger laps, giving some pointers on how to get around QR in general. If you go to my channel, it should be there. Brake markers are tricky heading into it but the key thing is slowing up more than you think for the first left hander.

Cheers man. Yeah, T6 is so much better. I could get on wide open throttle much sooner and the car stayed planted all the way around. The high temp and tired rubber was costing my quite a few tenths but overall, great to be back out there cutting laps. Are you rolling in a Lexus now?

My balls were insufficient and led to the failure. So, CV joint blew out basically

I can't comment on a comparison with the Vbox options, as I have not used any of their gear before. But, if you're after some simple telemetry and overlaid video footage, I can't fault the RaceChrono approach. For the price, it meets my needs. The dongle will give you access to whatever parameters you're car will share. You can even configure custom PIDs if you know the port and formula to interpret the data (e.g. the brake pressure data isn't served up natively but I have added for the BRZ I have).

I use an ELM327 Bluetooth dongle. You can use your phone's camera to record and use that footage, I don't because of where I have my phone mounted

Thanks. Love Morgan Park as a track.

I just use a simple Bluetooth ELM327 dongle, and pair this to Racechrono Pro with a Qstarz 10Hz external GPS. I did use a USB OBDII dongle but had compatibility issues. Bluetooth fits the need for me

@@lucas010888 Thanks, bro

The Ecliptech Shift-P2. Very customisable with patterns, limits, colours - all in the unit. Has an analogue input for oil pressure or similar warnings, plus stall warnings, battery voltage and a heap of other features. For the price, totally worth it.

Had to adjust the speed to 0.5 as I was going thay fast ;) Parts of it are sped up though to cut down on the play time haha

Yeah, the car sat a lot flatter through the corners and was a bit easier to control in the slide. Also changed direction a lot quicker on the switch back sections.

The alignment is more on the oversteer side (a bit of toe out), but was also pushing quite hard which led to over driving the car a little. Running factory sway bars - need to look into thicker aftermarket ones.

As long as it isn't a camel's

Cheers man. Your 370Z is nice and tidy. Was fun chasing Tom around in his Skyline.

Thanks red. Was going full send - as you probably could tell.

@@lucas010888 full send plus some 😅 💪💪🔥

You can export the Racechrono Pro data as a variety of file formats, such as VBO files to use in 3rd party overlay programs.

You can export VBO files for use with Circuit Tools (or similar programs), if that is what you meant.

Umm, it doesn't... lap times aren't always related to power.

@@lucas010888 Haven't raced at Lakeside for years but the old Datsun managed a under 60 second lap there. So I may know what I'm talking about?

@@FairladyS130 you'd think that, but here we are. If a car (me) is setting a faster lap time compared to them, then that makes me the faster car. You'd know that power does not maketh the lap time if you're getting 60s at LS. Any pleb can hit the throttle down the straight. The correct thing for them to do is to let the faster car past - as this was a Sprints event, not door to door racing.

I've seen some 'slow' cars do crazy good times But I've also been stuck on a straight behind a car whose Pb was 10 seconds behind me also

Pretty basic mods overall, MCA Red coilovers with 7kg front and 5kg rear springs, rear LCAs, equal length headers and e85, slotted front Forza rotors, Winmax W5 pads, Mishimoto oil cooler, blitz air filter, Ray's 57CR 18x9.5 wheels, Nexen SUR4G in 255/35R18 tyres, then harness bar and Ecliptech v2 shift light.

@@lucas010888 what made you go e85 with stock engine?

@Andrew Lesage more power, looking at a 30-40% increase over stock. Also burns cleaner and cooler.

@@lucas010888 wow, I didn't think it would make that much difference on the stock engine. What brakes do you run?

Also is the stock ecu able to be mapped on e85?

The brake pressure needs to be added as a custom OBD2 parameter against your vehicle profile. Have to configure the header, PID and insert an equation to extrapolate the values.

I use race chrono and would love the brake pressure on the overlay,​​⁠is this ​⁠easy enough to map ?? Will I need to find out how the car manufacturer maps the OBD output ​@@lucas010888 ??

Qstarz 818XT 10Hz

​@@lucas010888 I've just bought the same 818 GPS and my seller a trackie himself been using it for quite some years which he said set to 1hz instead of 10hz. Can I get your advise/opinion?

@redsiput44 I'm not entirely sure why the recommendation would be to set to 1Hz, since the polling rate would be no different to your phone's GPS. I use the 10Hz option without issue and it gives far greater accuracy, with laptimes being at most a couple of tenths off official timing - but often within a few thousandths of a second for accuracy.

@@lucas010888 Exactly my thoughts too while surveying external gps so let's move ahead wif 10hz instead. Tysm champ👍🏻

It is, you will need an OBD2 dongle, that will plug into your car. I use a Bluetooth one that sends the data to my phone, then RaceChrono uses this to overlay the data.

Yeah, still using those tyres in that spec

Study the layouts in advance, then study them some more, visualise them, then study again. Almost guarantee when you set off on the first run you'll forget where to go, the red mist descends and you get brain fog. As for driving it, smooth is fast but finding the right balance of being on the limit and not going past it (sliding is slow, generally speaking). Brake into the corner and into the apex under brakes to keep the front tucked in, then depending on the corner, feed the power in as you're unwinding the steering lock. You'll basically get into 2nd gear and stay in it the entire run. Some layouts may have you sacrificing the exit of one corner to get a better run into the next. So, you might exit shallow to give you a wider turn in for the next section.

@@lucas010888 Great tips, thanks so much. Should be a bit of fun!

RE003 example was a dry track. But day to day, the track can have varying levels of grip. Fun little experiment though, had to run the RE003 out of necessity for that particular day - hence the video

@@lucas010888 Do you prefer the Nexen's out of the two?

@@Rbraden for track stuff, Nexens for sure. They're considerably quicker than the RE003 on track, but wouldn't last as long (softer Tread Wear) compared to the Bridgestones. The Nexens manage ok in the wet, but the RE003 probably perform a little better in that regard.

59.57 during this session. My new PB now is 58.94 though.

@@lucas010888 well done, I had a 73 Camaro ,running on Hoosier crossplies ,best I did was 60.00 flat, on that circuit, I wanted a 59 anything,haha, stay safe mate

It was bound go happen [and after 8 years ;) ]. Born out of frustration from having lap after lap ruined :(

It is, not particularly fast though. But fortunately, other laps were cleaner
