AP Tuning along with RD Technik are pleased to announce another GLOBAL FIRST. We are now remapping the transmissions in Heavy Transport Vehicles and the initial results are blowing away all expectations and eclipsing results normally associated with traditional ECU tuning. While the R&D and programming behind this is extremely complex the application is simple and all via the OBD. So simple in fact the very first truck ever programmed was done so by the customer.
The first truck was a MACK with a 470 CCRS engine, working in hilly terrain typically around 65ton gross and achieving 1.6km/litre. This truck was simply described ( and excuse the pun ) as the dog of the fleet. Well this truck may still be a dog but it wears the badge proudly as it is now TOP DOG. The MACK is now the best performing truck in the fleet in POWER, TORQUE, Fuel Consumption an all around drivability. This MACK has gone from 1.6km/litre to 2.2km/litre which equates to37.5% fuel savings.
This is a game changer for the transport industry and the approach to tuning any truck in the future.
Anyone who has driven a large truck up and incline knows what it is to chase gears down, by remapping the transmission and slightly altering the power and torque curves we are able to make the gear changes far more responsive and therefore more efficient. The ability to catch those gears allows the truck to remain in the higher gears longer and get through the gaer range quicker when on the way up. The principal is not new, in the past we have addressed this issue by increasing power/torque from the engine to allow the vehicle to cope with the inherent lag in the transmission. By addressing this issue directly with the transmission we are simply able to achieve more with less, less power and less fuel.
It’s early days but it appears manual gearboxes actually benefit more, which is the opposite to what is observed on Cars and 4×4’s. The reason is simple, take for example shift speed, if altered in a manual car, unless racing, it is unlikely this constraint is hit with any great frequency whereas in heavy transport this is almost constantly hit.
So watch this space for further developments as AP Tuning and RD Technik continue to reshape traditional tuning .
