Map Scale Adjuster
What is this tool?
Paste ECU map values and quickly apply a percentage scale or a fixed offset. Useful for rescaling boost, ignition or fuel tables.
Use Cases
- Increase boost map by %
- Offset ignition timing
- Lean fuel maps slightly
How it Works
Scaling multiplies each number by your chosen percentage. For example, 100 scaled by 110% becomes 110. Offsetting adds or subtracts a fixed value so 100 with +5 becomes 105.
After adjustment each cell is clamped between 0 and 255 to match the 8-bit limits most ECUs use.
