RSD DTL (Datalogger) — FAQ

No — your phone is the datalogger. RSD DTL turns the phone already in the car into a full telemetry unit: GPS, motion sensors and (optionally) video. The only extra part is a cheap OBD-II/MaxxECU adapter if you want engine data. No wiring loom, no bolt-in kit.

OBD-II through a Bluetooth adapter, and MaxxECU. It also adds the phone's own GPS and motion sensors, aligned to the car — so even a car with no accessible ECU still produces useful telemetry.

Over a WebRTC peer-to-peer link straight to the RSD SRV server station, on ordinary 4G/LTE. Telemetry is about ~1 Mbps; with live video it's about ~5 Mbps up.

Nothing is lost. The full stage is always recorded locally on the phone, and the session auto-uploads to the server the moment signal returns.

Yes. It records the full-resolution video locally, and can stream live video (from the phone camera or an external car-mounted camera) alongside the telemetry.

It works on any modern phone (single-frequency GPS), but a dual-frequency GNSS phone (L1 + L5 — e.g. Xiaomi Mi 8/9/10, Pixel 5+, Samsung S20+) is the single biggest accuracy upgrade you can make in the car.

No. AutoCal re-seats the phone's orientation on the move — even after a mount bump — so there's no calibration stop.

No. Recording is movement-gated (it starts above ~5 km/h with a short hold), so a phone sitting in the service park produces no recording noise.

Direct engineering support from iDSLab — help with adapters, mounting and getting a clean feed to the server — through the website contact form or your in-account Messages. The app is English-only (rally teams work in English terminology); local Hungarian support is available.

Message us from your account or the contact form; pilot and partner teams get a direct engineering line. Bugs found in the field go straight back to the workshop — that's how the app is refined between events.

RSD DTL is a licensed product. Create an account, and once your purchase is processed an admin assigns it to you — then you download the install file from your account and install it on the car phone. It pairs with your team's RSD SRV server. For a pilot, contact us via the website.

RSD DTL and RSD SRV are both paid licences. If you were misled by the description, or the software doesn't satisfy you for a reason you couldn't reasonably have known before purchase, 70% of the price you paid is refunded — granted after an iDSLab review and discussion, on your provision of the relevant evidence.
