OBD2 – On-Board Driver Diagnostics
OBD2 – On-Board Driver Diagnostics
Not just for your car. For you.
Modern cars use OBD2 systems to tell you what’s wrong under the hood. As a driver—especially on track—you need your own version: On-Board Driver Diagnostics. That means recognizing your mistakes in real-time, understanding why they happened, and making the adjustment next lap.
It’s not just about corners—but let’s be honest, most of it is. That’s where time is won or lost, where grip gets used or wasted, and where good driving becomes great.
Running out of track on exit is a classic sign something went wrong earlier in the corner. It might feel like you’re attacking the turn, but if you’re forced to crank in more steering mid-corner just to stay on track, the problem likely started at turn-in. Which scrubs speed and kills your exit—or you run out of track and go off. One of two things is likely to blame:
1. You turned in too early.
2. You carried too much speed for the line you chose.
Or the opposite: if you find yourself having to “drive” the car to the edge of the track at exit—instead of the car naturally tracking out—then one of two things is probably happening:
1. You turned in too late, apexing late in the turn.
2. You didn’t carry enough speed through the corner to use the full width of the exit.
The common thread? You have to see what’s happening to know how to improve. Self-diagnosis is key. The data is right there—in your line, your inputs, your exit. You just have to pay attention to it.
And it goes beyond just corners: brake zones, throttle timing, shifting, traffic management—they all leave clues. The best drivers aren’t just fast—they’re analytical. They mentally rewind a corner or a sequence and ask: What could I have done better? Then they fix it.
Every lap is feedback. And every mistake is a lesson—if you’re willing to look for it.
