Beyond Basic Graphs: Professional Visualization and Math for All ECU Tables

Stop fighting limited tools. Get zoomable 3D surfaces and advanced smoothing for fuel, ignition, boost, traction control, and every calibration table.

The Industry's Calibration Problems

Visualization That Doesn't Help
You've seen it before: ECU software that shows a "3D" graph you can't actually examine. It's a static picture—no zoom, no rotation, no way to inspect that critical area at 85% load. You're left squinting at a tiny image, guessing what the surface really looks like.

Manual Smoothing Frustrations
Most ECU software doesn't include smoothing tools. You're left manually adjusting individual cells for hours, trying to remove noise from dyno or road tuning log data. It's time-consuming, inconsistent, and never as accurate as mathematical smoothing.

Limited Math Options
When you need to fill gaps or create smooth transitions between known good table areas, linear interpolation is often your only choice. It creates unnatural straight lines between points, ignoring how engines actually behave. The result is a calibration that looks right in the software but feels wrong on the road.

Inconsistent Workflows
Working across multiple tuning platforms means different tools, different interfaces, and different results. Having one consistent place to work on tables, with shapes that remain coherent between systems can be incredibly valuable.

SplineLab Solves These Problems

Examine Every Detail
Zoom in on specific RPM and load ranges. Rotate the surface to view from any angle. Our GPU-accelerated 3D visualization gives you the inspection tools professional calibration demands.

Mathematical Smoothing That Works
Apply Gaussian smoothing with adjustable strength to clean dyno or road tuning data in seconds, not hours. Remove noise while preserving real features. Get consistent, mathematically sound results every time.

Choose the Right Math for the Job

• Fill Missing Cells: Automatically complete partial tables with mathematically sound values
• Linear Interpolation: Simple straight-line fills between known points
• Spline Interpolation: Natural curves (cubic, quintic) that match engine behavior
• Gaussian Smoothing: Remove dyno or road tuning noise while preserving real features
• Partial Table Merge: Combine histogram data or partial tables with existing tables using adjustable blending

One Consistent Workspace
Work across all your tuning projects in one interface. Copy tables from any ECU software, edit with professional tools, maintain consistent shapes, paste back without reformatting.

How It helps your workflow

Instead of guessing at a static image...
You zoom into the 4,000-6,000 RPM range, rotate to see the surface profile, and immediately spot a dip in the fuel curve that linear interpolation would have missed.

Instead of accepting jagged transitions...
You apply spline interpolation or localised smoothing to create a map that follows the natural flow of the engine or traction behaviour.

Instead of working blind between known good data points...
You fill gaps with mathematically sound values that maintain the table's overall shape and prevent drivability issues.

Instead of majority of your time table smoothing and merging...
You simply merge and smooth all or selected areas in a few clicks to whatever level you require.

For Tuners Who Need More Than Basics

If you've ever thought:

• "I wish I could see that area closer"
• "Linear interpolation doesn't look right here"
• "I need better tools than my ECU software provides"
• "I really need this table to be smoother"

This is for you.
