Mail In ECU Calibration
Send us your ECU — we write, test and return your custom calibration
What It Is
Can't make it to us? Send your ECU directly to Tamworth Tuning and we'll write a custom calibration entirely in-house. Stage 1 remaps, DPF deletes, EGR deletes, AdBlue solutions and NOx sensor remaps — any software service that can be written to an ECU can be done remotely via our mail-in service.
Prefer to drop off? Bring your ECU to us in person and we'll have it completed within 24 hours — no waiting around, no chasing updates.
Once we receive your ECU, we back up the original file, write your requested calibration, bench-verify the work and ship it back with full documentation. Your original file is always preserved and the calibration is fully reversible.
Signs You Need This
- You can't travel to our workshop but want custom-written tuning — not off-the-shelf generic files
- You're local and want your ECU turned around within 24 hours — drop it off and collect the next day
- Your vehicle requires ECU removal for bench access and you'd rather we handle the full process
- You want a specialist deletes service without visiting in person

Important — Before You Book
Please contact us before sending or dropping off your ECU to confirm your vehicle's ECU type and the exact service required. Shipping costs for the mail-in service are included in the price.
