## What is PullScan?

PullScan helps drivers understand what’s happening inside their automotive datalogs.

Upload a supported CSV datalog or screenshot and PullScan analyzes the run, highlights important findings, and explains the evidence in clear language.

SUPPORTED LOGS
• JB4
• MHD
• Bootmod3
• Additional supported CSV formats and datalog screenshots

ANALYZE YOUR LOGS
Review important signals including ignition timing, boost, fuel trims, fuel pressure, AFR, throttle behavior, intake temperatures, and more.

SEE THE EVIDENCE
Interactive evidence and graphs show where important events occurred in the log and help you understand why they matter.

COMPARE & TRACK
Compare datalogs with overlay graphs, create vehicle profiles, and keep your analyses and log history organized.

SHARE RESULTS
Share analyses with other enthusiasts or tuners using PullScan’s sharing tools.

BUILT FOR ENTHUSIASTS
Whether you’re reviewing a pull, checking a new setup, or trying to better understand your vehicle’s behavior, PullScan makes datalogs easier to explore.

PullScan is an informational analysis tool and does not replace professional mechanical diagnosis or tuning advice.
