Troubleshooting

Almost always the wrong account. Layouts are per sign-in. Check the address at the top of the picker: it says Synced to <email>, or This device only when you are signed out or not Pro. Signing in with the other address brings them back.

The table wants a channel this log does not have, or a math channel that was deleted. The panel offers Choose replacement… with a dropdown per missing slot, so you can point it at a channel from this log without rebuilding the table. If it names a math channel, check it still exists in the Math Channels manager.

A dashboard built on another car is bound to channels this log does not have. Right-click the gauge: if the role cannot be resolved the menu leads with Not available in this log and offers channels to map it to instead.

• An HP Tuners channel reads differently than in VCM Scanner. Scanner applies per-channel display units from your tune, so a MAP channel stored in psi can show as inHg there. BigData converts by quantity instead, and always shows US units.
• An .hpl trace looks smoother than you expect. HP Tuners logs are put on an even 25 Hz grid so every channel shares one time base. A channel logged faster is reduced to that.
• A Haltech channel looks like a staircase. Haltech logs different channels at different rates and the export repeats the last value between updates. That is how NSP draws them too.
• SCT measured AFR looks like lambda. Because it is. SCT names the channel AFR but logs lambda, so it is treated as lambda rather than mis-scaled.
• A Holley digital input has the wrong name. Standard Holley channel names come from the firmware layout; your configured analog inputs are read from the log, but some digital input/output names still come from the reference layout. The values are right, the label may not be.
• A Holley .dl and its CSV export start at different times. The .dl is zeroed at its first sample; Holley's CSV keeps the negative pre-trigger time.

Expected while the app is in beta and not yet signed. Click More info, then Run anyway. See Installing.

Graphs draw from a reduced set of points, but histograms bin every sample, so a very long log with several tables takes a moment on each change. Setting Range to Selection so a table only bins what you are zoomed to, disabling tables you are not using, and raising Min Hits all help.

Send the log and a line about what you expected to see. If a log fails to open for a Palm Beach Dyno address it is uploaded automatically and looked at without you doing anything.
