We have a dual mass flywheel? All this time I thought it was a standard plate.The dual mass flywheel can make for rough 1-2 shifts. You need to get the release and the throttle application timed just right to keep it from bouncing a bit. It can be done but it takes lots of practice to get it right.
MazdaEdit will fix that. There is a table for the expected gear ratios.I could physically change the gearset, but the ECM which calculates and displays which gear you're in would get confused. It does a calculation of roadspeed versus rpm (when the clutch is fully let out) - and this'd change if I change the gearing. Ah, the complications of modern cars...😐.
Not sure if I would agree with that. If you are trying to accelerate quickly, having to delay the 1-2 shift for smoothness would qualify as "spoiling" the car to me.Its there but something you quickly get used to tbh. It doesn't spoil the car. Oddly it's worse in my wife's 2.2D, or perhaps that's her clutch control.
Seeing as how rev hang is controlled by the ECU then yes it could be dialed out as part of a tune. It wouldn't hurt the cats at all. All it does is prevent the lean spike generated by the sudden closing of the throttle plate.I wonder if a tune could be developed to increase, albeit mildly, the rate of rpm drop between gears. However, that'd be at the price of pre-cat and cat life expectancy. The precat is spendy 'cuz the exh header is integral with it. I'd be reluctant to muck with the dual mass flywheel, what with engine balance issues possible.
