Lesson Lesson 9 of 10

Not marked complete

From Bytes to a Structured Table

This cumulative exercise reuses the six-byte sequence from the table lesson. Work through position, arithmetic, selection, structure and a documented transformation, then compare selected results with the tools. It is not a vehicle tuning, file-validation or flashing workflow.

Supplied sequence

This invented sequence is also used in earlier supplied-table examples:

Offset     0   1   2   3   4   5
Hex       0A  14  1E  28  32  3C
Decimal   10  20  30  40  50  60

Worked example

Work the sequence before using a tool

Input

Use zero-based offsets. Select four bytes starting at offset 2; arrange them as 2 rows × 2 columns in row-major order.

Operation

Offsets 2–5 contain 1E 28 32 3C (decimal 30 40 50 60). The table is 30 40 / 50 60. At 110%, multiply each cell, round to a whole number, then clamp to 0–255.

Output

The transformed table is:

33 44
55 66

For the full six-byte sequence, the additive modulo-256 sum is 210 decimal (0xD2).

What this tells us

These are position, shape and arithmetic results for the supplied values. The table has no established units or ECU function.

Check each step

Which bytes are selected by offsets 2 through 5, inclusive?
What additive modulo-256 result comes from all six bytes?
Which table results from scaling 30 40 / 50 60 by 110%?
What have the selection, table and calculations established about a real ECU?

Verify with the tools

After making your predictions, enter all six bytes in the Checksum Calculator and compare its additive result. Enter the four selected bytes in the Map Extractor with a 2 × 2 shape, then use the decimal table in the Map Scale Adjuster at 110%. These tools confirm only the documented operations on the values you supplied; they do not identify map boundaries or meaning.

For a reminder of why supplied profile labels and heuristic matches need separate interpretation, revisit Testing a Supplied Profile Label and Troubleshooting Supplied Data and Tool Results.
