RPM jump when upshifting

roy'sz

[QUOTE=Spikuh;1619759]Incorrect. Simply get in the car, turn on SRM, start driving and rev to 4k, shift from 1 to 2 and don't release the clutch. You will notice the RPM's do NOT drop back to idle. They hold considerably higher somewhere near 3k.

That is rev matching.

most of the people on this forum would agree that what you have just stated is incredibly false. When you drive do you hold the clutch down and wait for the speed to match the gearing in your car for the correct shift? I didn't think so. It doesn't work with up shifting. If you read the owners manual and understand that the purpose of srm is for the lazy way of "heel to toe" the brake and gas when downshifting and matching rev's with gears while DOWNSHIFTING, not upshifting.

For the bolded part. It is a very oversimplified example, which I probably should have stated. Of course there is more going on with an upshift, but unless you want to wear out your clutch super fast, letting the RPM's drop some between upshifts is a good idea.

For the rest of what you said, I am going to have to back up to your first quote and restart there.

You said:

The part where you say SRM does not match upshift is categorically wrong. It says so in the manual:



SRM does not think, "Is he downshifting or upshifting?" It thinks, "Is he shifting?". Look at it this way. If you are upshifting from 1st to 2nd going from 4k RPM's to 3k RPM's, then SRM is going to hold the throttle at 3k RPM's while the clutch remains engaged. Similarly, if you are downshifting from 3rd into 2nd from 2k RPM's to 3k RPM's, SRM is once again going to hold the revs at 3k RPM's while the clutch is engaged.

Her is a youtube video of it in action on both upshift and downshift. Start at the 50 second mark if you want to skip his little intro. No idea who this, I just did a quick search.



So TLDR:

-I should have given a more thorough example.
-SynchroRev Match does work on upshifts.

As for whether or not SRM is the lazy man's heel-toe? This is irrelevant to the point you made in your first quote and is therfore...still irrelevant. As to the purpose of SRM, that is also irrelevant to the point you made as we are talking about how and not purpose.
