    Has anyone tuned using a cylinder pressure sensor?

    A quick post to ask if anyone has used a cylinder pressure sensor to tune a tdi. VW are planning to fit pressure sensing glow plugs to some of their range this year, for closed loop combustion management, so I guess the price of the plugs is set to fall (hopefully they will fit other tdis)...
