Fuel level

Not found. The standard PID (2F) is not supported, and the one candidate, 763 local 05 byte 12, sat still for three hours of driving (details).

How to find it: log every module’s blocks over a long drive (an hour or more) or across a fill-up, then look for a byte that falls steadily as the fuel does, or jumps at the pump. The engine (7E0, 104 blocks) and 763 (the likely cluster) are the first places to look. Many dashes show a smoothed level, so the raw sender value may jitter.

Boost above about 22.5 psi

PID 0B is one byte and stops at 255 kPa absolute. A three-hour drive peaked right there, so the real peak may be higher.

How to find it: log the engine’s blocks (7E0) alongside PID 0B during a few full-throttle pulls; a byte or word that tracks 0B below the cap and keeps rising past it is the uncapped pressure.

Gears 3–8, and byte 14 in D

The transmission’s byte 28 and byte 13 are confirmed for P, R, N, D, 1 and 2 only, all parked. Byte 14 was seen leading byte 13 in the manual gate; it still needs checking on real upshifts and downshifts in D.

How to find it: read 7E1 local 08 on a drive through all eight gears, noting when the dash changes.

Parking brake

A window was recorded with the parking brake applied (11:11:57), but nothing has been decoded from it yet. The foot was on the brake at the same time, which makes it harder to separate.

Transmission fluid temperature

7E1 local 02 byte 5 − 40 behaves like it, but has not been checked against a scan tool or a warmed-up drive.

Tire pressures

Not looked for yet.

The other modules

Nine of the fifteen modules have nothing decoded: 77B, 716, 718, 71C, 73A, 790, 7A8, 7B6 and 7F1. Their part numbers are on Modules; looking them up would say what each one is.

Brake pressure unit

The value is clear (0 at rest, ~9,500 for a hard stop), the unit is not. 0.01 bar fits. A pressure gauge on a bleed nipple would settle it, but a gauge only needs the range.
