Question about the SRM

JARblue

Dreamer has, imo, very clearly explained why you are not experiencing SRM engine revs during upshift - it's your manner of driving. Not to mention the link that he provided is quite informative. If you accelerate in 1st, then put the shift knob in neutral and let go (so it centers between 3rd & 4th gears), the tach needle will eventually drop to around your normal idle RPM. To then shift to 2nd would require an increase in RPMs for a smooth shift; with SRM ON, it will rev match for you when you move the shift knob to the 2nd gear gate regardless of whether you let the clutch out or not.

Why shouldn't it work that way? If I wait a hair too long to reengage the clutch and the RPMs drop slightly lower than the ideal for the gear shift, I'd rather SRM jump in and rev up for me a hair than make the car jerk cause of a mistimed clutch engagement. I understand your point about slow shifts, but you don't seem to get that SRM is supposed to do that. Under casual driving I would say it's better to let SRM correct your slow clutch engagement by increasing RPMs than engaging the clutch too quickly before the RPMs have dropped sufficiently.

I used SRM to learn how the car wants to shift. Now that I know how much the RPMs drop on an upshift in different gears and at different speeds and acceleration rates, I leave it off and make smooth shifts (most of the time) without SRM's aid.
