What Stage 1 Actually Is

Stage 1 Means No Hardware Changes

Stage 1 is a remap of your BMW’s standard engine, nothing bolted on, nothing removed. We read the ECU, write a calibration for your exact engine, fuel, gearbox and condition, and prove it on the rolling road. Boost, fuelling, timing and torque limiters are all reworked together and kept inside the safe operating limits of the hardware that is already on the car.

That is the difference between a custom Stage 1 and a generic one. A file bought off a shelf has never seen your car. Ours is written live with the BMW strapped to a V-Tech VT-4 4WD linked dyno, so xDrive cars load all four wheels and the figures you are quoted are the figures you actually get. Stage 2 is the step beyond, and needs hardware.

Locked BMWs

Post-2020 G-Series? We Unlock In-House

BMWs built from around June 2020 have encrypted MG1 and MD1 ECUs that most remappers simply cannot write to. We bench-unlock them in-house on our own bench, same visit, so a locked G20, G30 or G05 gets its Stage 1 remap the same day rather than having its ECU posted off to a third party.

Wow what a result 45hp and almost 100nm increase on my 2018 BMW 520d Xdrive msport touring. They also did the stage 3 XHP ZF gearbox tune aswell and lets just say the 2 hour drive home and little blast on the M6 toll road was hella fun. TOTALLY transformed the way the car drives and responds. …

This is not my first time with DC Remapping and every time I've had a csr to remap, the owner has not only out done himself, but has made sure the maps are safe, reliable and plenty of power! My first Audi A5 3.0tdi did 60k on stage 1 and never had any engine issues from it. Now I've returned with my BMW X4 and he's done it again! …

I Highly recommend DC Remapping, I took my 2011 BMW 535d. I knew it was not in the best of health and these problems would affect the map readings. Initial run 288bhp now that was with a stage 1 tune already (supposably) removed that tune now 256bhp should be 295bhp. New tune installed and gearbox remapped also, 327bhp. …

Stage 1 FAQs

BMW Stage 1 Remap, FAQs

How much power does a BMW Stage 1 remap add?
It depends entirely on the engine. A 20d typically goes to around 230bhp, a 30d to about 330bhp, a 35d up to roughly 390bhp and a B58 petrol to around 420bhp. As a rule of thumb expect 20–35% more power and up to 40% more torque, with the biggest real-world gain being mid-range torque rather than peak figures. Check your exact car for its own numbers.
Is a Stage 1 remap safe for my BMW?
Yes, when it is written properly. Stage 1 works within the safe limits of your standard hardware, we never push beyond what the turbo, clutch and internals can reliably take. Every map is developed live on our dyno while we watch boost, fuelling and temperatures, which is exactly what a generic off-the-shelf file cannot do.
Is a BMW Stage 1 remap reversible?
Completely. We keep your original file, so the car can be returned to standard whenever you want, before a dealer visit or when you sell it.
Do I need any hardware for Stage 1?
No. Stage 1 is software only on an otherwise standard car, which is the whole point of it. Stage 2 is the next step up and does need hardware such as a downpipe or intercooler.
How long does a BMW Stage 1 remap take?
Allow around two to three hours for a Stage 1 on the dyno, and it is a same-day job. Adding xHP gearbox software or an in-house ECU unlock is done in the same visit.
Where are you based?
20 Trinity Ct, Birchwood, Risley, Warrington WA3 6QT, 2 minutes from J11 of the M62 and 5 from J21A of the M6. Most of Manchester, Chester and Cheshire is a 25–35 minute drive, and customers travel to us from across the UK.
