I didn't go for the sports chrono so I may go with the MT sprint booster. Anyone here think otherwise?

Order the SC, if you like to fang it or drive on the track. Else the PSM will Nannny the car.

Another thumbs up! I've been following this thread for awhile and finally took the time to try it...I had verified the effect on my car previously but didn't make the switch mod. Wow, what a difference! The improved response is very noticeable and is a nice improvement. It did not feel it too touchy off the line and I really enjoyed the stop-and-go to work today. First to second seemed much snappier. So yes, it does work for Caymans.

Stock '06 CS, short shifter, no chrono or PASM

Too late to order SC, my car is built and currently on a ship.

I should simply purchase both MT sprint booster & Auto Sprint booster, and sell the one I decide against at a discount.

I doubt the 30 day trial would apply for those living outside of the US.

Sorry, thread highjack...

I put up a short article how I modified the switch (I made a short jumper to replace the switch).

I'm guessing, though of course not 100% certain, that unplugging the switch = incomplete circuit = CEL or code.

Word to the Wise...

Be careful when testing this. If it doesn't work, over-rev is a distinct possibility. Be ready to let go of the clutch or turn off cruise quick if revs start rising rapidly.

Engine damage caused by modifying this switch and over-revving the engine would rightly be denied by Porsche.

It's encouraging to read that the cruise doesn't de-activate because of this switch. I wonder how it knows the clutch is in if it's not from info provided by this switch?

I'm very happy with this mod. The benefits are mostly felt in spirited driving. Upshifts are more rewarding with a stronger burst of forward momentum on clutch engagement. Heel/toe downshifting is most improved with quick throttle response and a sharp "huff" of intake note.

I feel no loss of drivability. It definitely feels different, but better. I haven't come close to stalling it, as others have reported. My cruise control does not cancel when I push in the clutch, but I'm in the habit of tapping my brakes to cancel the cruise anyway.

I accomplished the mod with a jumper wire and 2 crimp-on spade connectors. I removed the switch so it wouldn't experience unnecessary wear. It was super easy.

FYI my car is an 06 Cayman S without Sport Chrono.

sayporsha · #**167** 10-20-2009, 04:02 PM

CORRECTION - My cruise control DOES cancel when I depress the clutch pedal. In my initial test I jumped the gun & tapped my brakes when I saw a blip in the tach reading. I decided to try it again & it works.

2009 Cayman non-S with 6-speed.

Mixed news:

1] Mod definitely affected drivability for the better. I much prefer the clutch-delay thingy to be disabled.

2] Unfortunately, taping the switch down gave me a (very annoying) "Drive Off Assist Failure" message and a red exclamation point. (!) on my dash, front and center.

Soooooo, I gotta decide whether I prefer the clutch delay (sucks) or the perpetual error message on my new Cayman (sucks).

Otherwise, LOVING my new Cayman!!

Any advice appreciated.

I really think, don't think I'm being condescending, that developing driver skills will improve drivability better than this crutch. Try spending some quality time with the car and my bet is the need for assistance goes away and you will feel better about your new found ability.

24hourcampfire · #**170** 10-29-2009, 04:58 PM

Hmmm. I think maybe you didn't understand my post. I HATE the clutch delay, as well as the DOA. I tried to nuke it using the mod, however, disabling the switch in my Cayman results in an error message, so I'm stuck choosing between having a perpetual error message and (maybe) some type of electronic issues, or living with clutch delay and DOA enabled.

**Santa Fe** · #**171** 10-29-2009, 06:10 PM

I guess I've never encountered the clutch delay in my '06. But haven't driven the newest model yet. I've owned a ton of different cars and merely note that all take some getting used to or adapting to.

Nexus-6 · #**172** 10-30-2009, 10:35 PM

Neat to see this thread still alive.

I wanted to share a new bit of info I've discovered. I purchased a 2005 Carrera S about 5 months ago. It did not replace my Boxster as I firmly believe the 987 is the absolute finest driving machine on the planet. I only feel qualified to make this statement because over the years I've owned pretty much one of everything it seems - this isn't necessarily a good thing. I spent way too much $$ on cars and have recently realized that I had a real problem. Why didn't anyone tell me I had a car addiction problem sooner? It honestly wasn't much different than being addicted to drugs!

The 997 did replace my '07 335i however. I must be getting old but no matter what platform, or how little lag there is, I just do not like the rubber band response of turbo cars. NA only for me from here on out to the grave me thinks.

Anyhow, guess what? The clutch switch in the '05 Carrera S does the same thing as my Boxster, as does defeating it. The C2S has PSE so it's even more noticeable on that machine when the clutch switch is working as intended - drive off in 1st gear results in the flatulent braaaaap during clutch take up as well as relatively sluggish throttle response post shift. Defeating the clutch switch in the C2S has provided the same results as my Boxster. The one difference I've noted is that the throttle is hyper responsive in the 987 with this little modification, whereas it's not nearly as touchy in the 997.

Lastly, for what it's worth...I prefer my 987S head and shoulders above the 911. With the Softronic plenum+tune and Remus cans, it's a tick and I mean just a tick slower than the 997 - to illustrate using a VERY loose comparison, my Boxster S with said modifications trips a measured stretch of road at 107mph. Same stretch, some conditions and the 997 will hit 111mph. Around town, the Boxster is much more fun to pilot.

The balance in the 987 shames the 997 honestly - don't get me wrong, the 911 is a fun car and allows me to enjoy a Porsche daily with the back seats (I have a 4 year old wee girl), but the 987 is a very special machine. I don't give a hoot what most people think in terms of prestige or pedigree with these two cars - in my opinion, the 987 is the better machine in nearly all ways. I'd sell the 911 before the Boxster any day of the week.

Now I must go and hide before the 911 faithful beat down the front door and burn me alive...

UPDATE - I reversed this mod because it started to get annoying in everyday use. I never did stall it, but it was difficult to control the engine speed during stop & go traffic & parking lot maneuvers.

I do miss the positive effects of this mod in spirited driving, so I plan to re-do it with a switch to turn it on & off - like a sport mode.

Interesting. I just tried the mod for the first time. Just used some aluminum tape to do it as an experiment. I stalled the car backing out of the driveway, but after that, I find it's more direct and linear. I like the mod with SC in Sport mode better than Normal mode.

Going on a road trip soon and will decide later.

I've stalled this car more than any other I've ever owned with the clutch switch working. I think it feels more predictable with the switch disabled. Performance is better off the lights and the car feels lighter with this switch disabled when actually, it's about 2 grams heavier...(the tape).

I had to press the clutch in with Cruise Control on just to verify that it wouldn't immediately peg the engine to red-line. As everyone said...It worked fine. Not that I don't trust ya...just that a thing like that...you want to verify a thing like that in a safe environment when you're thinking about it rather than on an expressway when traffic stops in front of you.

WARNING: Don't do the clutch delay mod if you have any hope of permanently reversing it!

Oh, you'll easily be able to reverse it, but you just won't be able to leave it that way.

I tried. I tried hard to eliminate the memory of how natural the clutch felt with the stupid delay disabled. I tried hard to like the Driver Assist, almost convincing myself it was a GOOD thing.

BAH HUMBUG!!!!

This weekend, I just couldn't resist. A little electrical tape later, and I ain't goin' back to stock! Error Message be damned!

The car feels SOOOO much better. Much more natural and direct control of the interface between clutch and accelerator.

And screw tha driveoff assist: HAAAATED IT!

Now if someone can tell me how to eliminate the error message on my display, then great. Otherwise, it's there to stay.

I HATE clutch delay, and I HATE Drive-off assist!

Whoever thunk to stick those abominations in a Porsche was smoking crack.

**Carmona Red** · #**176** 01-08-2010, 10:51 PM

I followed Nexus-6's instructions and removed the top clutch switch.
I wrapped a strip VELCRO around the switch with the pin in the "in" position. I then
velcroed the switch to the switch mounting bracket. Very neat, simple and easy to reinstall when needed.

Hey Campfire, what model/year are you driving? No error message on my '06 CS, ever.

And +1 on your comment...I can't believe how much better the car is to drive now.

Oh, and to add a plug for Red, I just added the Dream 1 exhaust...frees the engine a bit and smoothed out some rough rev spots...these two mods are the best bang for buck you can do. This site rocks! Where else can you find such a collection of knowledge about your car?

My '06 is also warning light free. All I had to do was tape the button down in place. It's a very weak spring, so I think it will stay until I remove it, which will be approximately never.

I used that aluminum tape with the strong adhesive. It also works over your stick-on wheel weights to keep them from falling off due to heat from brakes at DEs.

Na...the BEST bang for the buck you can do is to fix your Bose system by stuffing some pillow stuffing...as much as possible...in the subwoofer enclosure that sits in the passenger footwell. Improves the bass and all the other frequencies too. I couldn't believe what a difference it made. If you have Bose, you must do this one. It's in the Articles section.

**Veloyellow** · #**180** 01-09-2010, 06:35 PM

+1...the Bose mod was the first thing I did to my car
