Removes the *.hex/maps_cache gitignore rule (explicit user call, reversing the earlier no-redistribution stance) so the official TuneECU catalogue maps, derived SAI/O2-delete composites, and the checksum/composition tooling are actually available to pull up on a phone browser when using the real TuneECU app. Also folds in tonight's KWP2000 fixes (TesterPresent keep-alive, connect-failure cleanup, slow-init StartCommunication fix) and the accumulated research docs.

# External research pass — verified findings only (Aug 2026)
|
|
|
|
A web-research agent was dispatched with a brief covering this project's
|
|
open questions. Its raw report contained real value mixed with fabricated
|
|
detail (invented a table-category split not present in a cited source,
|
|
guessed at least one dead URL). Everything below has been **independently
|
|
re-verified by this project directly against the actual source** — the
|
|
raw report and the dispatch brief that produced it have been deleted; this
|
|
is the distilled, trustworthy result, not a summary of the report.
|
|
|
|
## Confirmed
|
|
|
|
**`0x53822` device flag — Purge Control Valve, strengthened.** TuneECU's
|
|
own `tests.html` (this project's site mirror) lists a distinct, real
|
|
testable entry: *"Purge Control Valve (Only bikes with charcoal
|
|
canister) — Activate the purge valve, listen for a very quiet noise,"*
|
|
right alongside its own separate SAI entry. Confirms Purge Valve is a real
|
|
device on this ECU family with its own dedicated path — genuinely
|
|
strengthens (doesn't prove) the leading hypothesis for this byte. Also
|
|
confirms "Air Flap (675 Daytona)" is Daytona-675-specific, per the same
|
|
list. Full detail and remaining uncertainty: `reference-maps/DEVICES.md`.
|
|
|
|
**Wideband sensor bung masking is real and worth designing around.**
|
|
Confirmed via a real installer source (RB Racing): long/angled 18mm bungs
|
|
and thread-reducing adapters (18mm→12mm) can prevent the sensor tip from
|
|
reaching the core exhaust gas stream, causing delayed/inaccurate
|
|
readings — *"Many manufacturers use long 18mm O2 slanted bungs. These
|
|
'mask' the 18mm O2 sensor signal"*; thread reducers are *"junk... too long
|
|
masking the signal."* Practical implication: check bung depth/angle
|
|
against the sensor's spec before assuming any available bung (stock or
|
|
new) works. Folded into `TUNING_IMPL_PLAN.md` Phase 2.
|
|
|
|
**Zeitronix ZT-3 — a third real wideband option.** Sold by Woolich Racing
|
|
as a tuning-package wideband kit. Adds to the existing list (Innovate
|
|
LM-2/MTX-L, AEM X-Series UEGO). Folded into `TUNING_IMPL_PLAN.md` Phase 2.
|
|
|
|
## Explicitly not carried forward (checked and rejected, or unverifiable)
|
|
|
|
- A claimed "Speed-Density vs. Alpha-N" table split in a Keihin SH7054
|
|
XDF listing — checked the actual source, no such split exists there;
|
|
the page instead lists a 3-cylinder table set, meaning the wrong
|
|
product (likely a Triumph triple's XDF, not this twin) was cited.
|
|
Don't reuse this claim.
|
|
- A specific Woolich Racing product URL for wideband bung fitment — the
|
|
exact URL doesn't resolve to a real distinct page; the general product
|
|
line exists but this project couldn't confirm it covers the correct
|
|
(Keihin, air-cooled) ECU generation rather than the later Bosch/
|
|
liquid-cooled T100. Same wrong-generation risk this project has hit
|
|
repeatedly elsewhere — don't cite this source without re-confirming
|
|
ECU generation first.
|
|
- A Reddit thread claimed to discuss map `20262` availability — could not
|
|
be fetched or verified at all (Reddit blocks this project's tooling).
|
|
- Claims about TTP's "TuneLoader" licensing mechanism and Ultimate Twin
|
|
Performance's remap-service pricing — plausible, not independently
|
|
checked.
|
|
- A Manitoba emissions-inspection regulation citation — checked, the
|
|
specific regulation number cited does not match what's actually
|
|
findable; not relied on for anything, not detailed further here.
