Default Downshift Rev match

Hi guys,

Just want to get everyone's experience on this real quick

I normall blip the throttle 1k rpm while rev matching from 6th to 5th, 5th to 4th, or 4th to 3rd. However, when revmatching from 3rd to 2nd, I actually need to blip harder, if that makes any sense, to rev match ... how about everyone else? I have a MY05 if that helps.

I think it has to do with the ratio of each gear. It is quite normal. I do it in my car all the time.

It's due to the gear ratio as stated above.

The larger the difference between the two ratios, the larger the difference in RPM will need to be.

1st gear - 3.133
2nd gear - 2.045
3rd gear - 1.481
4th gear - 1.161
5th gear - 0.942
6th gear - 0.763

yeah the ratios have to deal with it. the lower the gear youre shifting in its a higher rpm you have to rev to i think. when im going 30 in 3rd and downshifting to 2nd i have to rev to a bit above 4k.

Yeah it was like that my Prelude also. I was never able to do a smooth/fast rev match to 2nd gear. I feel like a lighter flywheel would take care of it.

i double clutch 2-3 shift, 3-2 shift, 5-6 shift and sometimes when its cold, 1-2 shift.

unless im having fun revving high seems to make the shifts go in easy.
