ECU Remapping Nantwich

Car Remapping For
Nantwich Drivers

Our only workshop is in Birchwood, Warrington, about 36 to 38 miles from Nantwich, so allow around 55 minutes off-peak. Engine and gearbox booked together cost £125 less, and a locked BMW ECU is opened in the same appointment, so one visit covers both. Stage 1 custom dyno tuning costs from £449.

Is Your ECU Locked?

From about June 2020, BMW and Audi ECUs left the factory encrypted.

Built Before June 2020

Usually not locked. Build and registration dates can differ, so check a 2020 car first.

Built June 2020 To Mid-2026

Locked. A BMW is unlocked on our bench as part of the tune for £100 more, without extra time. An Audi unlock is charged separately: most are done here in the same appointment, £449 with the tune, and sending the ECU away costs £399 and keeps the car with us for 3 to 4 working days.

Built From June 2026

A newer lock that can't currently be opened, so we can't tune or unlock these BMW and Audi models for now. Email sales@dcremappinguk.com with your reg and we'll tell you when that changes.

The reg check reads only the public DVLA record. Some newer VW, SEAT, Skoda and Cupra models with a Bosch MG1 or MD1 ECU are locked too, and a few engines, such as the 2024-on 2.0 TDI, can only be sent away. We have a 100% unlocking record so far, and should an ECU ever not survive unlocking, we supply and code a replacement at our cost (see ECU unlocking).

Gearbox Software

Doing The Gearbox On The Same Visit

Booking gearbox software with the engine map takes £125 off the pair.

BMW xHP, £325

Most E and F series BMWs with the ZF8 automatic. With a £449 Stage 1, the pair comes to £649.

BMW xHP, £385

G series BMWs, M cars, the X1 (F48) and 2 Series Tourers. With a £449 Stage 1, the pair comes to £709.

VAG DSG And S tronic, £325

Covers ten VW Group gearboxes, DQ200 to Aisin AL1000. Paired with a £449 engine map, that is £649 for both.

We are an official xHP Gold dealer, and xHP is installed in person, so the car has to be here. See xHP gearbox tuning, DSG and S tronic tuning or our engine and gearbox packages.

Expected Figures

4WD Linked Dyno

The Same Rollers For Every Car

Our V-Tech rollers are linked front to rear, which matters for an xDrive 530d or a 4Motion Golf R.

Nantwich To Birchwood

Two Ways To The M6

Nantwich is about 36 to 38 miles away, around 55 minutes off-peak, with no tolls and no charging Clean Air Zone on either route.

One way is east on the B5074 and the A500 to junction 16, then about 26 miles north on the M6. The other runs north on the A530 to Middlewich and along the A54 to junction 18. At the northern end, exit at junction 21 (B5210, then A574) or continue to 21A and use the M62 as far as junction 11.

Stapeley and Audlem reach the A500 by the A51 and A529, and from Acton and Wrenbury the A49 north to M56 junction 10 is another option.

Nantwich FAQs

Locked ECUs, Gearboxes And The Drive

How do I check if my BMW's ECU is locked before driving from Nantwich?

Our free reg check reads the public DVLA record for your registration. If the car was built from around June 2020 to mid-2026, the ECU is locked, and we unlock it on the bench during the same visit for £100.

My Audi has a locked ECU. Is it still a one-day job?

Usually. Most Audi ECUs are unlocked here in the same appointment, so you leave the same day, and the unlock is a separate charge of £449 with your tune. A send-away unlock costs £399 and means leaving the car with us for 3 to 4 working days, which is the only option on a few engines. Both are listed on our ECU unlocking page.

Which xHP stage should I choose?

ST1 removes the factory torque limiters and keeps the standard shifting. ST2 adds a full gearbox remap with quicker changes. ST3 is the race-level stage, and it is the one most of our customers choose.

How long does the drive from Nantwich take?

About 55 minutes off-peak for the 36 to 38 miles, by the A500 to junction 16 or the A530 and A54 to junction 18. Worleston is nearer 50 minutes; Audlem and Wrenbury about 65.

Do you offer mobile remapping in Nantwich?

No. Engine and gearbox work is done at our Birchwood workshop with the car on the dyno, and xHP can only be installed in person.

How is payment taken?

0% finance with Bumper is available. A £50 deposit holds your slot and the rest is paid on the day by card or cash. Paying in full online? Choose Klarna at checkout.
