LOA HEX is what happens when the tuner builds the platform.
Built in a small UK workshop. Run by the engineer who actually opens your file. Designed so nobody sits between you and the person doing the work.
Why we exist
We were paying the middleman to slow us down.
For years, every file that came through Voodoo Motorworks went out via a third-party tuning portal. They held the relationship with our customers, took a cut on every file, and charged us between roughly £500 and £1,500 every month for the privilege. When the portal went down — and it did, mid-job, more than once — we were the ones explaining to a customer in the bay why their van was still on the lift.
The frustrating part wasn't the money. It was that the portal wasn't doing the work. The tunes were ours. The dyno time was ours. The customer trust was ours. The portal sat in the middle, collecting fees and adding latency.
So we built our own. LOA HEX is the same tunes, by the same engineer, with nobody standing between you and the file. Customer bins no longer pass through someone else's hands. Our library lives on our own infrastructure. The pipeline is ours, end to end.
The name
Loa, hex, and a crossroads.
In Haitian Vodou, the loa are the spirits at the crossroads — the place where the human world meets the spirit world. We picked the word because every ECU file is a small crossroads of its own. Stock on one side. Tuned on the other. A decision in the middle.
Hex works two ways. It's hexadecimal — the language an ECU actually speaks. And it's a hex, a small spell, a nod to the voodoo theme that has run through the workshop since the beginning.
The mark — three strokes meeting at a single point — is a simplified veve: the symbol drawn in voodoo to summon a loa. Three roads, one centre, one decision. That's the picture we wanted on the door.
The veve. Three crossroads strokes, one centre.
How LOA HEX works
Two paths. One promise: no babysitting.
Auto-deliver
If your ECU is in our validated library, the bot matches the file, builds the tune from the proven calibration, runs a checksum, and the tuned bin lands in your dashboard. No human in the loop, no queue.
Tech handoff
If it's a one-off — odd hardware, unusual modifications, a calibration we haven't seen — it lands with our tuner directly. You get an email when it's ready and a note on what was changed.
Checksum-verified
Every outbound file is checksummed. If the bytes don't match what we built, it doesn't ship.
Full audit trail
Every upload, every match, every tuned file is logged with timestamp and checksum on your dashboard.
Dyno-tested where possible
Library calibrations are validated on real cars in our workshop before they go out the door.

Who's behind it
Voodoo Motorworks. Independent. UK-run.
LOA HEX is built and run by Voodoo Motorworks, an independent tuning shop in the UK. The same engineer is behind every file on the platform — the same person who has been remapping cars out of the workshop for years.
There is no faceless tuning desk in another country. No escalation queue. If something on your file isn't right, you phone the workshop and you get the person who built it.
