Run the new MAFSync DataLogger and capture your engine's airflow through a clean patch cable I provide. No cutting, no hacking. Send over the logs, and I'll dial in a calibration built specifically for your engine. Flash it, and run 100% MAF-driven.
Run the new DataLogger to capture your airflow and get a calibration dialed to your engine. Or, if your engine's already supported, grab the ready-to-run module and go.
Capture your airflow with the new DataLogger, and I build a calibration dialed to your engine.
Already running a supported engine? Skip the logging. Get a pre-flashed MAFSync module and matched MAF, then plug in and drive.
A self-contained logger that runs off your car's power and serves its own dashboard. No laptop tethered under the dash, no software to install. Just open a browser.
Ships with an 80mm MAF sensor included and is built around the M30B35 big-block. It also suits other large-displacement BMW inline-six applications given the correct coupler or adapter.
| Included MAF | Bosch HFM5 · 80mm hot-wire sensor |
| Housing | 80mm, sized for big-block airflow |
| Target Engine | BMW M30B35 3.5L, plus compatible inline-six with adapter |
| IAT | Integrated intake air temperature sensor |
You're capturing the airflow signal from in front of your AFM using a patch cable I provide. It plugs in inline with nothing spliced, cut or modified, and it all comes back out when you're done.
Connect the provided patch cable inline at your AFM to capture the airflow signal, position the 80mm MAF in front of the AFM, and hook up power, ground, and your RPM/O2 leads. No cutting, no hacking. Reach out if you'd like a hand with mounting.
The logger self-hosts its own web interface. Join its WiFi network from any phone, tablet, or laptop, open 192.168.4.1, and pull up live telemetry and data right in your browser. Nothing to install. Connection steps.
Drive normally: cold starts, highway cruising, and wide-open throttle. Logging runs automatically in the background while your car keeps running on its factory AFM the whole time.
From the Web UI, open your logs, download them, and send them over.
I dial in your calibration from the data and send back a finalized file. Flash it straight from the Web UI on the device, or via direct USB to the side port for a more robust load onto the MAFSync board. The logger keeps doing its thing throughout.
As an early adopter, your logs help expand engine coverage. Questions before ordering? Message me via Instagram DM or email.
