Just a thought
anyone agree??

I actually disagree. I notice a delay with the SRM. What you may have to do is get to a cruising speed (I recommend ~50mph), put in neutral long enough for the SRM to "deactivate". Then put in 2nd. There is definitely a delay in it climbing up. I'm sure of it. It's just less perceptible since you aren't accelerating. It's only visual there.

The computer can get a reading from the gas pedal and respond in less than 1 microsecond. There shouldn't be a *perceptible* delay between reading the pedal and the car reacting.

Any more Group buy codes for this? Also will this work for the 2011 model? They say it's for the 2009-2010 but I assume it still should work.

I did not try it.

Honestly, if you don't really experience it or have found a way to drive around it I'd just do that. Or just boost the thing and forget about it forever.

i just notice it doesnt drop the revs very quickly sometimes. like it revs up quick then holds and drops kinda slow. (in neutral) it could just the the flywheel but i thought the drive shaft is a carbon composite of some type so thats should let it rev pretty freely.

most of this could also be my head after reading topics like this.........
just gotta make it till 4 and go drive and enjoy it

You'll notice with regular driving that with SRM on, the engine revs hold for a moment while you are shifting gears. With SRM off, the revs drop much more quickly.

The mass of the flywheel does have some effect, but there is a very noticable difference with SRM on and SRM off.

hmm. interesting never considered that. SRM is fun to play with with you are hustling around a corner and the novelty will wear off im sure

but i will have to try driving with it off.

For me, my shifts were always smoother with SRM off. But you're right, it's fun blasting around some curvy roads. It makes you look like a pro... and helps you focus on the corners ahead instead of matching your revs perfectly, but that's half the fun.
