ECU Mapping summary

ECU Re Mapping service is generally a 3-4 hour job. When your ECU is programmed correctly with precise settings you will then notice a smoother more responsive and quicker car. Re-mapping of aftermarket ECU's for improved torque and power output is all done on a direct coupled 1600BHP Chassis Dynamometer. (Rolling Road)

The Dynapack 6000 is capable of measuring up to 1600 BHP on a 4WD vehicle... that's 800 BHP per axel.. The Dynapack is similar to a rolling road but directly couples to the vehicles wheel hubs This means there are no problems associated with tyre/roller slip, increasing the safety and accuracy of measurement. This is perfect for analysing faults only apparent when driving under load and tweaking the engine for maximum power output.

Large ceiling fans suck air from outside and pump it into the cell through a radiator sized appeture and then extracted via a large ceiling vent and exhausted outside. Exhaust gases are extracted seperately.

The equipment is able to measure in real time the engine torque, air intake temperatures, turbo boost pressures and importantly the air/fuel ratio; BHP is calculated and corrected to British DIN standards.
