Tom,
Not surprised it did not work, considering the source of the info.
To pick your brain/knowledge --- In respect of the SVX, is torque induced via the interruption of fuel or ignition?
I have always understood that some, but not all cylinders, are deprived of ignition for the short periods involved. This would be plausible as control would be practically instantaneous, as opposed to a probable slight inherent delay.
Please, can someone confirm the exact mode of operation. Please, no opinions, only exact evidence, e.g. pointers towards verifiable published statements, from an absolutely reliable source exhibiting authority.
