BMW Chip Tuning
Up to 30% more power for your BMW
The BMW catalogue lists 583 engines (models: 23, generations: 65). For 77% of the engines, there are the GAN GT (up to 30% more power) and GAN GTL (up to 25%) tuning modules; for the rest, the GAN GA and GAN GA+ (up to 12%). Each engine’s figures are on its own page.
BMW chip tuning without an ECU remap
The tuning module sits between the sensors and the engine control unit (ECU) and adjusts their signals. Your manufacturer’s warranty is preserved: the ECU software is never changed, and the module can be removed at any time.

What BMW owners say about GAN
After first minutes of using, the engine thrust increased, I can notice a better response of the acceleration pedal, and the fuel consumption decreased (about a liter) . At this moment everything is perfect.
Very fast delivery, excellent customer service, smooth and quick processing. The module works perfectly and, thanks to the excellent user manual, is easy to understand. Installation was very quick and easy. The performance increase was immediately noticeable. I would gladly order from GAN again anytime. A very, very…
BMW chip tuning: questions
BMW tuning box or ECU remap: what stays untouched?
An ECU remap replaces the factory software in the engine control unit. The GAN module sits between the engine sensors and the ECU and adjusts their signals, so the factory software, checksums and flash counter stay untouched. Your manufacturer's warranty is preserved: the ECU software is never changed, and the module can be removed at any time.
What should I check on an N47 diesel before BMW chiptuning?
On the N47 (116d to 123d, 318d to 325d and others), the timing chain on the gearbox side is a known weak spot. A check or replacement is recommended from around 100 thousand km, and a rattle is the warning sign. Engines built between 1 March 2007 and 5 January 2009 are the most affected, though cases are known on diesels up to 2015. A tuning box adjusts sensor signals and does not touch the chain itself.
Are the B48 and B58 engines of the F and G generations covered?
The B48 is a 2.0-litre four-cylinder and the B58 a 3.0-litre six-cylinder, and both belong to the turbocharged B family that replaced the N series. Turbo engines mostly work with the GAN GT, so look for your engine on the model page by generation and hp.
What can a tuning box do for a naturally aspirated N52 or N53 six?
Both are naturally aspirated sixes, and the N52 dates from 2004 while the N53 was built from 2006 to 2013. For these engines the GAN GA+ is rated at up to 12% more power, and that figure is an upper limit. On an engine rated at 218 hp that means at most 26 hp more.
Does the GAN module affect my BMW warranty?
No. The module does not change the ECU software and can be removed at any time, so your manufacturer’s warranty is preserved. We also give an engine warranty: 2 years with the GAN GT, 1 year with the GAN GTL.
Tuning box or ECU remap: which should I choose?
An ECU remap permanently changes the maps in the ECU and leaves a trace in the flash counter. The GAN tuning module adjusts the sensor signals instead: the ECU stays in factory condition, and you can return the car to stock in about a minute.
BMW chip tuning: what to know about the engines
BMW tuning: the badge no longer tells you the engine size
Start BMW tuning with one misconception cleared up: the number on the boot lid stopped being the engine size long ago, and a tuning box is chosen by the engine family, not by the badge. The two digits after the series number once gave the displacement in decilitres, so a 318 had 1.8 litres and a 330 had 3.0 litres. With turbo engines the figure became a power class, and the 328i and 330i of the F30 are both 2.0-litre engines.
The letters add more: i is petrol, d is diesel, e is a plug-in hybrid, and x or xDrive means all-wheel drive. One name also covers several outputs, which matters for BMW chip tuning. The 116i made 116 hp in the E87 in 2004, 122 hp from 2007, 136 hp in the F20 and 109 hp in the later F20 and the F40.
Engine families decide the module
BMW engines come in families, and the family tells you more than the badge does. In the 2000s the petrol range was mostly naturally aspirated: the four-cylinder N42, N45, N46 and N43 and the six-cylinder N52 and N53. The N54 of 2006 brought turbocharging to the BMW petrol sixes, followed by the single-turbo N55 in 2009 and the four-cylinder N13 and N20 in 2011.
Since 2014 the modular B38, B48 and B58 have replaced the N series, and all of them are turbocharged. The diesels run from M47 to N47 to B47 in four cylinders, and from M57 to N57 to B57 in six. The catalogue pairs every engine with a module: turbo engines mostly get the GAN GT, rated at up to 30% more power, and naturally aspirated petrol engines the GAN GA+, rated at up to 12%.

What BMW itself did with the same engines
BMW sold its own Performance Power Kit for the 135i and 335i with the N55 engine. It raised output from 306 to 326 hp and torque from 400 to 430 Nm. The M Performance models, such as the M135i, M140i, M340i and M550d, are sold separately from the M GmbH cars, the M3, M4 and M5.
BMW body codes
BMW models go by body code: the 3 Series is E46 (1998–2006), E90 (2005–2013), F30 (2011–2019) and G20 from 2018. The 5 Series is E60 (2003–2010), F10 (2009–2016), G30 (2016–2023) and G60 from 2023. The 1 Series has E87 (2004–2013), F20 (2011–2019) and F40 (2019–2024).
The X3 is E83 (2003–2010), F25 (2010–2017) and G01 (2017–2024), and the X5 is E53 (1999–2006), E70 (2006–2013), F15 (2013–2018) and G05 from 2018. The 2 Series coupé is F22 (2013–2021), and the 4 Series is F32 (2013–2020) and G22 from 2020.
Which BMW models are in the catalogue
The catalogue lists 23 models from BMW. The most engines are listed for the 3 Series (98), 5 Series (96) and 1 Series (52). The biggest gain among the models is on the M5: up to +106 hp.
Naturally aspirated BMW engines
For 134 naturally aspirated engines from BMW, there is the GAN GA+: up to 12% more power and up to 15% lower fuel consumption in ECO mode. You can fit it yourself, in most cases in under 15 minutes.
