What to put on the ticket so Stage 1 comes back the same day
The dump is half the job. Hardware, fuel, gearbox and a readable file name do the rest. Vague notes are how a same-day Stage 1 slips to Thursday.
Reviewed by the lab desk before it went live. We write files; we do not rubber-stamp brochure numbers.
Same-day Stage 1 is normal on this desk when the ticket is complete. When it is not, an engineer sits on a 2018 320d with no fuel type and a file called scan2.bin. That is not a remap brief. That is a guessing game, and we do not guess boost on a customer’s Monday.
Start with the read. Full ECU dump, not a 200 kb snippet, not a screenshot of WinOLS. Put it on Dropbox, Google Drive or MEGA and paste the link. Five megabytes covers almost every genuine read. If the tool spat out two files, send both and say which one you flashed last.
Name the file like a person who opens twenty of them before lunch: make, model, year, engine if you know it. BMW_320d_2018_EDC17.bin beats final_FINAL3.bin every time. In the notes, write fuel, gearbox, and what is still factory. Stock intake, stock exhaust, dual-mass already noisy — that helps. Make it angry — that is not a parts list.
Stage matters more than people think. Factory downpipe still on the car? Order Stage 1. Downpipe and a freer intake already fitted? Say so and pick Stage 2. Mixing those two is how you get a limp mode and a customer in reception. We would rather move the job up a stage than send a file that assumes air that is not there.
Gearbox is its own line. Extra torque on a DSG that still thinks it is protecting 380 Nm feels lazy on the next shift. Want the TCU done in the same visit? Attach that read and put the box code in the notes. DQ250 is not DQ381. A ZF 8HP in a BMW is not a Mercedes 9G. Mileage helps. A tired clutch pack does not enjoy a sharper map.
What delays a file in practice: a Drive link set to restricted, a dump from a different chassis, no year, and a ticket that says same as last week with no job number. What does not delay it: a short, ugly paragraph with the truth on it. We read ugly. We cannot invent a hardware list from a smile.
A few notes that save a revision. Say if the car already has a map from someone else. Say if the DPF or the downpipe was cut last winter and put back. Say if the customer wants a calm track car or a weekend toy that only sees a closed circuit. Those two briefs are not the same file, even when the grille is identical.
Credits come off when you open the request, not when you think about it. Rejected jobs put them back. Unsure between Stage 1 and Stage 2? Open Stage 1, write the parts list, ask in the job chat. The chat sits on that ticket. It is not a Facebook thread from 2019.
A photo of the bay is fine if you have one. It does not replace the dump. A VIN in the notes helps when the same shop sends three Golfs in a week. That does not replace the read either.
Circuit and motorsport only — same sentence as the rest of the desk. The ticket is how the file gets written to the car in the yard, not how someone argues with an annual test. Fill it once. Then the Stage 1 can leave the same working day.
