When setting up an MT7 calibration prior to doing a data run, is it nessecary to set the CLB to 664mV across the board on both cylinders?  (as shown in the instructions) and if this is the case shouldnt the rear cyl be different to the front?

Cheers for that guys, for some reason i got the idea in my head that all the cells had to be the same prior to the VTune run.
