The AI lab for machine firmware
We read, map and safely rewrite the software inside engine and machine controllers — and use it to make American agriculture, and the fleets around it, stronger.
The machine is yours.
Its software isn't.
- Every machine is run by firmware its owner can't read. It sets the power, the shifts, the derates, and whether a replacement part is accepted.
- The dealer is the only door. A derate in harvest means days of downtime on a machine that earns its keep in weeks.
- The independents don't own their tools. They rent closed suites and can only sell what those vendors support. In ag, what's on offer is mostly emissions deletes — illegal, and not engineering.
One stack.
Owned end to end.
rcflash runs from the USB cable to the checksum — one Rust codebase, ours.
- · Every common cable, plus our own dongle
- · UDS, KWP2000, J1939, GMLAN
- · Maps and code, checksums repaired
- · Remote: our tuner on your cable

Ground truth for map inference. Analysis on Ghidra — the NSA's open-source RE suite — plus our own tooling.
A checksum the community worked around for years
Bosch ME7's sector checksum had been patched around, never solved. We solved it — every sector, every sample.
“Every null result needs a positive control.”
The method — and why the remaining families are a queue, not a wall.
We change the logic
Every tool on the market edits tables. Our shim framework compiles a Rust function per controller family, places it in free flash and redirects the OEM call — reversibly.
- · New governors and limits for fleets
- · Maps on more axes than the OEM shipped
- · New logged parameters for external loggers
Sold as engineering, not as a file
Why this compounds
No vendor gate, no per-unit tool tax, cross-platform, remote.
Custom controller behaviour, sold as engineering.
5,665 variants and 901,201 labels — training data for map inference.
Problems the industry routes around become our queue.
Versioned, auditable changes. Emissions systems stay in.
Queue to reviewed calibration; every file feeds the lab.
Four curves crossing
State ag right-to-repair statutes and federal enforcement against repair restrictions. Agriculture leads it.
Ghidra open-sourced, Rust on embedded and desktop, cheap CAN hardware.
With a labelled corpus, map and label inference is a modelling problem — not years of manual work.
Every model year widens the gap between what the hardware can do and what the owner may do.
American agriculture first
- Expensive machines, brutal downtime. A flagship combine lists above half a million dollars and earns its keep in a few weeks of harvest.
- A mixed fleet on one bus. Bosch EDC17 and EDC7, Cummins, Denso and OEM controllers — all on SAE J1939, which we already speak.
- Owners want out of lock-in. Farmers have led right-to-repair and won the most ground.
- Served worst. The market offers delete kits. We offer engineering: calibration within compliance, module programming, derate diagnosis, fleet programs.
Three segments, one stack
Measured in the repo, not promised
Target is the full catalogue. These bars are today's numbers — the ones a diligence call will reproduce.
What we've built
Service first, platform last
File service volume · Scanmatik driver · native recipes on top modules · agents draft, humans sign
RP1210 + J1939 flash · 3–5 design partners in one region · fleet program productised
Commercial fleet programs · shims in production · first model-drafted map pack
rcflash licensed to shops and repair networks · map-pack API · dongle on-ramp
Emissions systems stay in
Tampering law covers farm equipment as well as road vehicles. Delete shops live with that risk; we built the company so it isn't ours.
It is also the position delete shops can't move into.
- No deletes, no defeat devices
DPF, EGR, SCR, catalysts, sensors and monitors are untouched — on road vehicles and nonroad engines alike.
- Enforced in the tool
Emissions tables are flagged in our atlases; patches that touch them are refused.
- Every change is versioned
A full diff per machine: what changed, what didn't, and a byte-exact revert.
- Inside the repair exemption
DMCA §1201 covers vehicle and farm-equipment software for repair and lawful modification.
The people doing the work
Runs the company: customers, ag and fleet partners, and the raise.
Built the rcflash stack: transport, protocols, checksums, the corpus and the platform.
