Per the title... this CD system is causing many vibration and smoothness complaints. On the 3 - CD is in place regardless of which transmission is used... and FWD + AWD. The savings in fuel appears to be miniscule. Mazda appears to have shot itself in the foot with this "innovation". C'mon, Mazda :(.

Yes... 'cuz a module was commercially available to do this. That's what our brothers over there need.
A little resistor on the temp circuit that fools the computer to think the engine is never warm, and as a result it does not activate the variable cylinder management system, brilliant.

Not really, as in addition that results in the PCM also changing the fuel maps so it likely destroys fuel economy at the same time, and might contribute to fuel dilution in the oil too (which is definitely not a good thing.) The best option would be a tune that eliminates the deactivation in the PCM code.

Agreed, it that were the case with the Mazda then it would be a good idea to not interfere.
In the case of the Honda there are two sensors for temperature. One for the gauge and VCM and another for fuel mapping. I obviously used the one for VCM and gauge (yes it moves a tiny bit down but it is the new normal now)
