Ford Transit Connect 1.5 tdci diagnosed with a adblue and dpf fault once this was rectified we then added a remap, with a remap power has now risen from 118hp to 145hp and torque has risen from 300nm to 340nm. These are little bit harder than simply reading and writing through the obd port, you have to read and write the dcu through the obd port, but bench the ecu as this can not be read or written through the obd port.
