Definition files allow raw binary data to be represented logically. They are the critical link between programmers and tuners - neither is much use without the other.

"Because there's money in selling these codes (sometimes upwards of $50,000), the industry has little incentive to embrace the community (p. 65. Smith) Malicious actors have damped public and community progress for decades and "...wont be motivated to share their findings" (p.64, Smith)

Two Main forms:

*.kp - imported/exported from WinOLS (full version)

- Rare in public.
- Purchased or leaked files
- Linked to expensive software

*.XDF - imported/exported from TunerView

- Common in public
- Can be created from *.kp files via scripts
- Freeware and community driven

Other Damos (A2L) - is a file that includes descriptions of all* maps. Ideally a leak from mfg service department, or OE tuner. Rarely does it contain "Every" map or byte/bit value.
