BMW 1M TUNING
The 1M coupe was BMW M's second turbocharged engine (after the S63 V8 which debuted in the X6M). Since the 1M Coupe's N54 engine was also used in the E89 BMW Z4 sDrive35is, the 1M Coupe is only the second M model, after the Z8 and E39 M5's shared S62, to use an engine shared with non-M models. The outputs for this engine are 250 kW (335 bhp) at 5900 rpm and 450 N⋅m (332 lb⋅ft) from 1,500 to 4,500 rpm. An additional 50 N⋅m (37 lb⋅ft) is produced during overboost taking overall peak torque to 500 N⋅m (369 lb⋅ft). The only available drivetrain is a six-speed manual gearbox with an M limited slip differential.
At GCAP Performance we have a few hardware and software modifications to help boost the power on your 1M.
We use an Akrapovič exhaust system on our tuning packages for this vehicle.
Utilizing a single muffler arrangement, the fully titanium AkrapovičSlip-On is designed to be modular. In its basic mode, all exhaust gases flow through the muffler, giving you a deeper rumble of an exhaust note compared to stock without any drone. However, the muffler system is built in such a way that by replacing a blocking plate with the optional Akrapovic sound kit valve system the driver is able to noticeably increase the volume of the exhaust at the press of a button. Once activated, the majority of the exhaust gases route through the muffler bypass outlets. Even when installed on an otherwise stock vehicle, power gains are achieved and weight reduction realized. Complete the look with a set of four exquisite tailpipes in titanium or carbon fibre.
We have developed our own software to increase the cars performance. This comes in two forms. A stage 1 map (I.E. a software only calibration with no hardware changes) and a stage 2 (with our Akrapovič exhaust system).
When tuning we measure afr, ignition timing, intake temps, EGTs etc. to ensure our tune is as safe and reliable as possible whilst drawing the most out of your supercar.
We have seen gains up to 420bhp.
As with most BMWs, the brake system is excellent. However we can offer modified braided brakes lines. Our lines have a stronger wall density delivering a more precise and accurate brake pedal feel. This translates into more confidence in your sports car.
