Car Remaping & Tuning in Gloucester

N57 30d Engine (258 BHP)

This engine provides both great performance and economy, its a real gem in the BMW engine line up and is know for its smooth progressive power delivery.  The N57 30d is a 3.0 Litre straight six diesel single turbo lump controlled by the Bosch EDC17 CP50/56 ECU coupled to a ZF8 automatic transmission.  Tuning these retains the awesome power delivery but makes them on par with the more powerful 35d engines.

We have tuned in excess of 500 of these engines Stages 1 & 2, our extensive R & D on this platform has led us to be making industry leading power figures, fast real world performance whilst maintaining reliability.   We have had a F15 X5 30d on fleet for 4 years which we have used to perfect our engine tuning on.

Stage 1 Tuning

Stage 1 tuning requires no mechanical modifications, typically we see these hitting 320 - 330 BHP, 660 - 690 NM of torque.  Most people opt for Stage 1 Tuning as all the factory emissions system are left alone, the car remains MOT compliant and there are no visual modifications. 

Stage 2 Tuning

Please Enquire

Gearbox Tuning

The ZF8 transmission is controlled by the Getrag TCU, whilst in stock format the box works well we can transform the box to behave in a much sportier fashion, improving shift points, shift times gear displays and adjustment of the maximum torque limiter.  These boxes are easily capable of reliably dealing with 900 Nm of torque. 

No matter what stage of tuning selected all cars are custom tuned on our mechanically linked (X drive safe) 4x4 rolling road.  BMW's X Drive system cannot be safely ran on a normal non linked rolling road and damage to the transfer box will result.  Whilst we see many companies unplugging transfer boxes or disabling the 4 x 4 system via software to run them on a two wheel drive dyno this is far from ideal and often results in massive over readings of torque.   

Before and tuning work commences your car is put on our rolling road, full diagnostics carried out and data logs  taken to establish the health of the vehicle. DPF regeneration and minor adaptions are all carried out before tuning where required at no additional cost.

We are also a BMW AOS approved dealer to carry out software updates, servicing, reviewing service history, recalls and the like.
