Stage 2 ECU remap
Stage 2 is not simply a stronger Stage 1 file. It must be matched to the exact intake, exhaust, cooling, turbocharger and transmission configuration declared by the workshop.
Controlled from identification to delivery.
Why the original file matters
ECU family alone is not enough to identify a safe calibration target. Hardware number, software number, update state, reading method and file integrity all matter. AllChip OS keeps the original read and automatic identity result beside the selected vehicle profile so a mismatch is visible before work begins.
What to send
Upload the unedited original read whenever possible. Add identification files, ECU labels, diagnostic codes, hardware changes, fuel grade and the customer’s technical target. Clear input creates a faster engineering decision and a more traceable result.
After delivery
The result remains attached to the operation with its timestamp, status, engineer note and revision history. If further validation is needed, the workshop can send logs or supporting files without losing the original context.
Before you submit.
Can a standard car use Stage 2?+
Usually not. Requirements differ by platform, so the calibration team must review the actual hardware before accepting a Stage 2 target.
Do you provide Stage 2 power estimates?+
Where the supplied database contains verified projection fields, the vehicle laboratory displays OEM, Stage 1 and Stage 2 estimates side by side.
