"over an electronic limiter" - what the heck are you talking about?

Does the 7AT double-clutch on up-shifts? My homeboy in auto-shop class who knows a lot about cars said that double-clutching is a must if you want to go faster.

No, the Z does not have a double-clutch transmission.

Damn...500 milliseconds ain't bad. It would have been better if they shaved that down to half a second, though.

That is half a second.

Wait...so you need a double-clutch transmission to do it? He has a '94 Prelude and he swears it's hella faster when he double-clutches, but I don't think he has changed the transmission. He says he beat his homeboy's dad's Mustang GT if he double-clutches, but he loses if he doesn't. I was just wondering if the 7AT could do the same thing. Is there a button you can press for it or something?

WTF are you talking about?

500 of something can't be the same as half of something else.

You want it to be half of 500 milliseconds?

I'm still using an iphone app to figure out what half a second is in milliseconds. Give me a minute!

Huh???

does 500 not equal 1/2 of 1000 //// 1000 equal half of 2000

P.S. 500 miliseconds = 1/2 second

double clutching can only be done on a manual trans..... not an auto... and it feels like it makes u go faster but actually it just burns ur clutch faster and basically jus makes ur car jump for a split sec forward...
