1 – How do we work?admin2021-07-29T09:18:25+00:00Our technicians connect to the vehicle’s ECU or ‘brain’ with a laptop PC via the OBD (Onboard Diagnostic) socket, to take a read of the engine management file. This is then uploaded to our files team, who optimize the code and send it back to the dealer technician to reprogramme the ECU. Tuning via OBD normally takes around an hour,  The work can be carried out at  your home or place of work depending on location.

2 – Benefit of quality remap files?admin2021-07-29T09:23:06+00:00

Boston Tunings remapping enhances and optimises the power of the engine within safe limits. We are taking up the redundant capacity and high tolerance levels vehicle manufacturers build in – often to ensure that warranty claims are maintained to an acceptable minimum.

3 – Diesel Engine Benefits?admin2021-07-29T09:26:01+00:00

By far the most effective way to increase the performance of a diesel-engined vehicle is to carry out a remap, which does not require any hardware changes and leaves the existing systems (such as ABS and stability control) unaffected.

Our modifications are only carried out on engine calibration parameters; and because we understand the strategy that the ECU is programmed with, the conversions we make are not ‘fooling’ related systems. This means that:

 Nothing needs to be connected to the vehicle after tuning

 No loose boxes and wiring are left in the engine compartment

 Torque delivery is smooth

 Torque is adjusted/limited in lower gears to ensure transmission system longevity

 Boost pressure and air flow is optimised

 Infotainment systems will display correct fuel consumption

 Traction control / stability systems are unaffected

 Torque reduction when shifting gear (for comfort and durability) is retained

 Regeneration of the diesel particle filter (DPF) is retained

 Exhaust gas temperatures are correctly calculated and applied

 Service intervals are correctly applied

 The diagnostic system remains unaffected

 No increased NOx, HC, CO, CO2, or soot emissions compared with original when undertaking MOT testing

 The original calibration can be reinstalled if required

4 – Do you keep my original map?admin2021-07-29T09:27:15+00:00Yes, in secure archival storage, should you ever require your vehicle to put back to original.

5 – What improvements can I expect?admin2021-07-29T09:31:24+00:00A Boston Tune remap alters the fuel, boost, and torque characteristics of the engine by adjusting the fuel pressure, injected fuel quantity, maximum permissible visible smoke limit, boost pressure, and torque limits. The conversion offers a fully understood alteration to the engine characteristics, whilst still operating with complete feedback control, and within all preset engine sensor parameters.
