Tuning file service for professional tuners

You upload the complete original read, exactly as your tool produced it — OBD, bench or boot, whichever route you took. You state the vehicle, the ECU, the stage you want and the options. A remarks field covers what no form can guess: mechanical work already done, a known fault, a requirement from your own customer.

You get back a file ready to flash, checksums corrected, in the format your tool expects. The jobs we handle today split almost evenly between slave and master tools: both are daily business here, and a slave tool is never a reason to send you elsewhere.

If the read is incomplete, or if the ECU will not take what you asked for, you hear about it before your tokens are committed — not after.

Every request becomes its own WinOLS project. The engineer starts from the calibration family validated on the dyno for that engine, applies it to your read, adjusts what depends on your hardware, then corrects the checksums. That work cannot be automated — which is exactly why a file service exists.

The portal keeps everything: the original file, the delivered file, the engineer's remarks, the dyno graph when there is one. You can find a job again six months later without digging through your inbox.

The commitment is simple: 60 minutes maximum during opening hours, for a file that has already been developed. That is the rule of the service, not an optimistic average.

Here is what our database says about files actually delivered:

When a job runs beyond the hour, the reason is specific: the file had never been developed for that ECU or that engine. It then goes on the dyno before delivery, and you are told at submission that yours is a new development. We give no lead time in that case — a development is measured on the engine, not on a stopwatch. With 219 ECUs already handled across 72 makes, it is the exception rather than the rule.

Jobs submitted outside opening hours start at the next opening, and the clock starts then. The portal shows the current estimate and tells you when the workshop is closed.

Most of the jobs that reach us are not Stage 1 files: they are options on their own. A DPF, an EGR, an AdBlue, a list of fault codes to switch off on a vehicle that stays otherwise standard. Each option has its own page, with what it does, what it requires and what it costs in tokens.

You buy tokens and spend them when you have a job. A car Stage 1 costs 1 token; the token price runs from €120 down to €80 depending on the pack, excluding VAT. Tokens do not expire: a quiet month costs you nothing, unlike a monthly subscription.

The full price list is public — tuning types, options, trucks, gearboxes — and the portal computes the total before you confirm.

A delivered file is not a closed case. If the calibration needs adjusting — something you feel on the road, a requirement from your customer, a run on your own dyno — the revision is free and is requested from the job itself, with the full history in front of the engineer.

What is not refundable is stated plainly: a file delivered as ordered is not refunded, because it cannot be taken back. Better written down than discovered afterwards.
