Tomorrow i'm really fucking hopefully really seriously taking delivery tomorrow. My manual experience is >7 hrs total.

Basically i've been reading and reading and a lot of veterans constantly say CDV delete.

What exactly does that do the response of a clutch? Some people say that shifting into second will require a bit more slipping of the clutch, but from my practice it's like that with both vehicles i've driven so far.

car pick up location is bmw bayside by the way .....And i get to drive it back home on some northern blvd hills .

If you're coming from a Toyota and you have very little manual transmission experience, youre going to have a steep learning curve regardless of the CDV. Once you learn the car for a month or two then consider taking it out.

The CDV, as I understand it, exists at least in part to save the various drivetrain parts from shock, whether that be from hooning or from someone not knowing how to drive a stick. In our cars this pretty much baffles me. The CDV introduces some artificial "slip" between gear changes which makes it more or less impossible to dump the clutch and have direct engagement. It's obvious why enthusiasts want/need direct engagement of the clutch without the interference of this valve. You, however, shouldn't be worried about it until you log a reasonable amount of hours in your car.

If you remove the CDV, you'll gain not only direct control of clutch engagement but also a consistent engagement point with respect to pedal position. With the CDV still installed the engagement point is not consistent and this sometimes leads to you "bucking" the car and looking like you can't drive stick. Mostly, that's still the driver...but the valve doesn't help.

Don't worry about hills. If your car is in gear (which it shouldn't be while you're stopped at red lights - if you hold the clutch in for the duration of red lights you'll ruin your throw out bearing) the "hill assist" feature will prevent you from rolling backwards for 2 seconds even after you let off the brake. If you're sitting in neutral on a hill, however, you will roll back, so make sure you dont let off the brake before you pop it in first. The "hill assist" gives you plenty of time to work the gas and clutch without worrying about rolling into the car behind you.

Bottom line: pick up your car, read the manual before you leave the parking lot, get used to your clutch/car for AT LEAST a month and then, finally, worry about the CDV.

Enjoy
