CDV delete -- E46 BMW

[Crickett]

This, just need a throttle cable to perfect rev-matching. I hate Drive by wire, it makes a noticeable delay in response

Exactly why I'm beginning to consider a Sprint Booster or equivalent . . . !CDV helps, but it's only half of the equation.

To the people that said that the CDV delete makes rev-matching possible..

Are you saying you couldn't do it before? I can almost perfectly rev-match now with the CDV.

Depends on the change of gear and rpm. If is a small amount as in a normal downshift it isnt bad. But for example I wanted to keep up with my dad in my moms B8 S4 yesterday, I downshifted from 6th to 4th, trying to revmatch plunging the pedal, but the response was soo delayed. Nothing wromg, just how drive by wire operates.

Anyone ever driven a preracelift E39 540i with throttle cable 282hp M62 and then a facelifted with the drive by wire M62TU? 8 more hp and feels soooo much doggier. Still quick but there is a difference

I can actually get perfect rev-matches right now as my car sits (Shark Injector, CDV delete), but I still get less perfect rev-matches than I got with my E30.

I could do perhaps a 95% rev-match with the CDV, but I still felt a little "jolt", so minor, yet so noticeable. It still bugged the hell out of me that I was doing everything right but I couldn't dump the clutch without that stupid little judder.

I have. My brother's car was a 1997 540i with a 6-speed, and was the first manual car I learned to drive on. The throttle was nice, but the CDV made it almost IMPOSSIBLE to learn manual on. I started with the mentality that "this is going to be easy" because I already knew the concepts behind it, just never put it into practice. Then, when I went to apply those concepts, it all went to hell because of that stupid valve. I could never get a smooth start with it.

Then I went to a 75hp Russian car, that wouldn't even have a CDV as an option (It didn't even know what an option was, that's how basic the car was). I was driving manual smoothly within half an hour in that car.

The next time I drove a car with a CDV was my buddy's 2001 E39 525i. That also has a CDV, and those bad memories of a CDV in my brother's car came right back; it was very difficult to get used to. By the time I drove the 525i, I already was rev-matching perfectly in my E30, so my skill was great. Goes to show you how badly it messes someone up.

Then I got my car. I could rev match almost pefectly, but the fact that I could never rev-match 100% perfectly bugged the hell out of me. So, in essence, the CDV delete is probably the best mod I've ever done and will remain that.

I'm with you az3579 ... I learned on a 1948 Jeep (no synchro on first!) so I know about rev-matching. That CDV is headed for the trash next chance I get !

Like the title says,

Has anyone changed their clutch delay to a modified clutch delay?

if so did you notice a big difference, good or bad one?

Sarmen, I am going to merge your thread with this one: http://www.zhpmafia.com/forums/showt...122-CDV-delete

I'm going to see if I can get my dealer to remove my CDV.

Lol we'll see how this goes...
