Services & options
DTC off
When hardware is removed or changed (catalyst, sensors, flaps, secondary air pump), the ECU keeps logging fault codes and may trigger limp mode. Our DTC off service disables the selected diagnostic trouble codes directly in the ECU software, permanently.
Simply list the P-codes to remove when you upload the file. We deactivate exactly those codes and their escalation paths (MIL, limp mode), leaving all other diagnostics fully functional.
What the file includes
- ✓Targeted: only the codes you list are disabled
- ✓No limp mode, no MIL triggered by the removed hardware
- ✓All remaining diagnostics stay operational
- ✓Ideal companion for decat, swap and race builds
Frequently asked questions
How do I tell you which codes to remove?
Add the exact P-codes (e.g. P0420, P2002) in the comment field when uploading. If you are unsure, describe the removed hardware and we will identify the codes.
Is DTC off reversible?
Yes. Flashing the original file back restores the factory diagnostics. Always keep the original read.
Can you disable airbag or brake-related codes?
No. We refuse safety-critical deactivations and only handle engine and emission-related diagnostics.
