Fortunately, a 2017+ module bolts right on to <=2016 cars, just need to match transmission. No bleeding involved, just swap the module on the ABS block (2013 will need two wires repinned).

If a wheel speed drops and then recovers - the ABS could reducing pressure to just that wheel, or it can reduce pressure to all 4 wheels until the locked wheel recovers. Right? I run pedal dance and will occasionally get a small lock from the unloaded inner wheel if I trail brake too aggressively. Data shows a little downward spike in that wheel speed. Is the ABS action to recover to just the inside front or to all 4? It's a very short duration. |

I'm guessing you need to be logging faster than I am (10hz) to see that... This isn't the best example - just something I grabbed from the first AIM log I had on the laptop, but you can see ABS is intervening on separate wheels.
Not that I really trust the Solo 2 onboard GPS accel, but it is all I've got at the moment to give some kind of idea of what is going. You can see the decel G bleed off or flatten out after ABS intervention, to be fair. Channels separated Channels overlaid to better illustrate Don't make fun of my driving

So the abs is engaging just after the 1760 mark?

I figured it was modulating at 1520 and 1620, basically ignore everything after that. Maybe I'm wrong, I dunno. I'm not good at the data interpretation stuff.
I'll gather some data in the next month or so without pedal dance and try to A-B them.

Is that braking in a straight line? If you're turning, feel like we need steering angle to make sense of it

is it possible you're just modulating the brake yourself ? I have a fair bit of data when the TC is off with the 5 second hold. Never really noticed anything odd for wheel speed and brake pressure. Happy to share anything that might be helpful

Can someone explain to me, like I'm 5, how to data log these channels with an AIM Solo2DL (and how to actually get it to work with a smartycam 2.1?)

Open up RaceStudio 3, click gear icon in top left, click New, select Solo 2 DL, click ECU Stream tab, choose Toyota => GT86 Click the 10hz on the wheel speeds and set them to 20hz Go to the Display tab and build the views you want to page through on the Solo Click the Smartycam Stream and set your channels. For speed you're going to want to change it to ECU SpeedAverage Click Save, turn your Solo2DL on, connect to its WiFi network from your computer, then click Transmit on your new Solo 2 DL config. SmartyCam 2 is stupid limited on display stuff so you can't really get your individual wheel speeds to display live... I get oil pressure on my overlaid live data because I am using the Haltech CAN config instead of the BRZ chassis CAN. If you need more of a walk through I can arrange it.
