TCU & gearbox tuning
Engine output and transmission control must agree. TCU requests are reviewed using gearbox type, software identification, clutch limits and the associated ECU torque model.
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 TCU tuning be requested alone?+
Yes, when the gearbox, TCU software and current ECU state are clearly identified.
