OUR ENGINEERING
Every Push & Lift DDU runs on the same core: CSV·DDU, our reference-lap engine. This is what we actually bring to sim racing — not another dashboard skin, but the technology that reads a real lap and turns it into live coaching.
01 · THE ENGINE
Most overlays guess your braking point from a preset mark someone typed in for that car, on that track. Push & Lift doesn't. It compares your live telemetry — throttle, brake, speed, steering — against a real lap, one someone actually drove, resampled by distance around the track rather than by time. That's what makes the countdown, the live brake correction and the corner-by-corner delta work on any car, on any track, with no database of preset points to maintain.
We call the engine behind this CSV·DDU: a parser and comparison engine built from scratch for this app, not a wrapper around someone else's telemetry tool. It reads any CSV with Throttle and Brake columns — column order doesn't matter, the header row can sit anywhere in the file, and it auto-detects whether your values run 0–1 or 0–100, degrees or radians, km/h or m/s. That flexibility is deliberate: your reference lap can come from more than one place.
02 · TWO WAYS IN
Garage 61 runs quietly in the background while you drive in iRacing, capturing your laps automatically. Open your session there, find the lap you want — your own, or a faster driver's if it's shared with you — and export it as a CSV. Load that file into Push & Lift and you're comparing against a lap someone actually drove.
Also compatible: any tool that exports Throttle and Brake in a CSV works too — MoTeC i2, a generic iRacing SDK logger, whatever you already use.
03 · LOADING IT
Right-click → Reference → pick the CSV. A badge appears in the header:
From there, that one file drives everything: the 5-LED brake countdown, the live trace row next to yours, and the corner-by-corner BRAKE / PRESS / Δ readout.
Pro tip: don't chase the world record. Pick a lap 1–2 seconds faster than yours — close enough to copy, far enough to learn from. When you match it, upgrade the reference.
