ECU remap revisions: when a workshop should ask again
Three revisions sit inside Stage 2, Stage 3 and TCU base. They are not a new cart every time second gear feels wrong. Stage 1 is usually one clean file.
Reviewed by the lab desk before it went live. We write files; we do not rubber-stamp brochure numbers.
A revision is not a complaint form. It is the second sentence on a job that already has a dump. The car pulled fine to 3.500 and then felt lazy. Second gear flares on a DSG that still thinks it is protecting 380 Nm. Someone flashed Stage 2 on a stock downpipe and the dash lit up. Those are briefs. ‘Make it angrier’ is not.
On this menu, Stage 2 BASE, Stage 3 and TCU base include three free revisions inside the same ticket. They do not open a new cart. They do not take another pack of credits unless the job itself changed — different stage, extra option, a second ECU family. Stage 1 is priced as one clean map for stock hardware. If the first file is wrong because the ticket was wrong, say so in the chat. We would rather rewrite than argue with a limp mode.
Ask for a revision when something on the car changed, or when something in the first drive is specific. ‘Knock under load in fourth at 2.800 on 98 pump fuel’ is usable. ‘Customer hates it’ is not. Mileage helps. A dual-mass that already rattled will rattle louder with torque. That is not a map fault. That is a part finishing a conversation it started last winter.
Do not stack three mystery files and then ask why the dash looks like a Christmas tree. If you added pops, EGR-off or a TCU file after the first flash, write that on the same ticket. The engineer matches the dump to the hardware list. A list that grew in the yard and stayed silent in the notes wastes a revision.
Rejected work puts credits back. A revision on an open job does not. That difference matters when reception wants to ‘just try Stage 2 as well’. Open the right stage once. Use the chat on that job. It is not a Facebook thread from 2019.
Keep the first dump. If the customer wants factory behaviour back after two revisions, flash the virgin read or order the original-file service. Cheaper than hunting a stick labelled copy3.
Circuit and motorsport only. A revision does not turn a track file into a street ticket. Tell the truth on the ticket. Then the second file can be a file, not a guess.
