I have heard that on some pcars you can get brake pressure from the ecu...nice!!! With obd2 cable, I managed to get steering angle, steering speed, throttle position, pedal position but only brake on/off on my camaro.

 

I get all 4 brake channels. Pretty interesting to watch the automatics do their thing when I mess up

 

If you want to stay with the OBDII connection, you can change the brake graph to long g to get a good approximation. You should be able to get throttle position. Hopefully the photos help you with where to look.

 

Thanks guys!

Got the throttle working fine and used the system this weekend. It is so incredibly user friendly I can't believe it. Starts and stops automatically. Downloads to my laptop quickly and is simply fantastic. Sadly I had a scary day and am really wondering if I should be doing this but at least I have tons of data and video so I can take a long hard look at myself . . .

Matt,

Is there a video or other thread that discusses the alternative CAN connection that allows for brake pressure recording? Is it just a different plug or do you actually need to do some minor wiring?

Thanks again for all the help. What a Great Product!! Worth every penny and then some!!


EDIT: This setup isn't ideal but I wanted something that wouldn't be annoying to an instructor if they didn't want stuff obstructing their view. Also I found that the cables fit snugly under the seat and behind the rubber weather stripping around the door so no wires were showing. Obviously I will move this upfront when I can, but for now I just can't get over how truly "Plug 'n Play" this was when combined with the RAM mounts!

Here is the complete guide for a 2011 Carrera both OBD-II and CAN. I think you need to check if your config on the Solo DL is just a basic OBD-II config (which does not include brake info) or whether it is specifically for your car (which should, as it is listed).

The direct wire installation is shown, but there are locations closer to the left footwell that the connection can be made.

BTW, there is MUCH more useful information that can be arranged on the background of that video. Stuff that will help you find out how to calibrate your internal accelerometers quicker and with less risk, as well as narrow your search for speed to those areas on track and technique improvement.

Good luck.

 

The document Peter linked to is the best explanation of the hookup for a CAN connection. It's a different cable that is $45 retail. I like the CAN connection for the increased amount of data and the lower likely hood that connector gets bumped or loosened causing a data problem.

 

Alright, forgive me guys as I know sometimes I can be a little "thick", but let me see if I have this correct . . . at the moment I am using an OBDII - CAN plug (On Board Diagnostic bus - Controller Area Network), but for $45 I get a CAN plug that will connect to my ECU (Engine Control Unit bus).

Assuming that is correct my question is: how hard is it to remove the seat area covers, and once the plug is installed can I put the seats back in place?

Thanks as always!

 

Ok, while Matt is correct in explaining that the CAN connection (direct wire) does add slightly more info and refreshes it faster, your current plug in connection will give you brake pressure on the video if:

a) the correct config is loaded on the Solo DL
b) the SmartyCam settings are correctly set in the Solo DL config (to associate the brake pressure Solo output with the brake pressure channel input on the camera to actuate the red bar)
c) make sure the red bar in the SmartManager 2 config on the camera is set to "brake pressure" instead of the default "brake position" and the upper limit set is max pressure Jonathan says you're supposed to reach in the hardest zone.

You have what you need, but it's time for you to find a local resource to help you set it up or cull through AiM Sport's Vimeo channel for further detail. I do set this all up in advance of sending new or used equipment to the end user and provide this service for customers who buy through me.

Also, you can call AiM Sports in Roanoke or Lake Elsinore and they can talk you through it.

Again, you have what you need, at the rate and with the channels you need, to do what you want once it's set up correctly.

 

Try using the cable you have and setting the Solo DL to "Porsche " "997-987_MK2_OBDII" protocol. Then, makes sure the Smartycam button I showed in the other photos is configured correctly, then configure the SCHD in SmartyManager 2. That should get it working.

If whoever you bought it from isn't helping, feel free to email me at matt@trailbrake.net or call me at 603-674-3250. I'm happy to help you get up and running. The folks at AiM can also help if you can't get me for some reason.

The CAN connection isn't a plug, but rather a wire with the CAN high and low, 12v power, and ground.

 

This is how I was configured for the weekend, and how the Solo DL/Smarty CAM are currently configured. Are you guys saying I should have brake pressure showing if I have the correct OBDII for 997.2?


(I didn't use "Brake POS" because under that option my only choices were THROTTLE, ACCELERATOR, FUEL not Brake)

 

Also just a brief aside, but I zoomed in on the data from my OFF and could see how the PSM system was varying the wheel spins. My front right tire was spinning twice as fast as the front left and the rears were spinning more than the front. That is so cool to see how the car is working to undo my stupidity. Not so cool I was stupid in the first place but cool technology all around!!

 

I know this is not a GM area but there are some big brains on here!!!...take a guess...do you think there would be channels getting data using direct wire can that are not getting data through obd2?

I'm using obd2 and have all that I could want except brake pressure using the C7 stingray profile. There is a braka pressure channel in the profile but nothing going in from my camaro ecu???...do you think trying the can cable might populate that channel?...I know it's only a guess???

I was always aware that obd2 is slower but in trackdays non f1 scenario I doubt the data speed makes any difference????

 

Yes.

Also, if the camera (in SM2) is listed as pressure instead of position.

I would switch your measures to F and psi.

 

That looks right. Plus, you can see the DL is getting brake pressure as it's the blue line in your chart. So, it looks like it should show up on your video correctly.

When you go into SmartyManger 2 and look at your screen setup, what is the setting for the brake graph (i.e. what is the high limit)?

 

Yes, yes and true.

I have not tested the direct connection on the C7 Z06, but will soon.
