Thanks...pressures are spot on.

Put some new rear tires on my car the other day and I noticed that at highway speeds when I accelerate my car seems to pull to slightly to the left and when I deaccelerate it goes back in line. It doesn't happen on every road but on I95 it occurs most. Is this a natural phenomenon do to the torque generated by the drive wheel (no LSD)? Could it be the new rear tires (Potenza 050A's) fyi the fronts are the same but are N0's and the new rears are N-1's. One of the technical guys at the tire rack said there are two different compunds between the N0 and N1 tires and said they should have only recommended N0's to match the fronts as the N1's will cause problems if mixed with N0's. Tire Rack is sending me a set of N0's to swap into.

Appreciate any feedback.

Thanks

I am on my second set on RE05As - been very good for daily driving and track. N-rated.

I must of nailed a pothole though as I developed a bubble or hernia on the sidewall at 10K miles.

Lots of wear left despite 2 track days,one AX, and daily commute.

Keep up the pressure for those low profile tires on 19s.

Regards,

Josh

Thanks, I try to keep the pressures as high as possible but also not too high (actually lower than the factory specs) trying to avoid the typical centers of the rear tires getting worn first and I must say they have worn very evenly.

N1 is a later approval of an N0 tire.

If it has an N approval you are good to go with it.

Sweet...thanks.

Thanks guys...the tiore rack has the N1 not the N0's...anyone know the diff?

The Tire Rack is out of the rears for an S..anyone know of another trusted and competitive source?

Thanks

Yes, could be ignition switch or clutch switch. If it happens again jumper the clutch switch to eliminate it.

Good thought...I'll either do that or just take it in. Thanks

Nothing. Tried it the second time and nothing...third time fired right up just like she always does. Checked the battery and it is strong. What could it be, bad ignition switch, bad switch for clutch pedal?

Thanks

BUMP...need updates from those with chatter...Skate???

Updates please

I tried the Techron trick. It actually seems to have worked.

I'm in South Florida...why do you think a bottle of Techron is not a good product/idea?

Thanks Paul...I don't know where race gas is available around here but I will add a bottle of Techron to the fuel which should clean things nicely as well.

Burn 5 gallons of race gas (101 octane). That should

clean up things abit. Add it to a tank that is

about half filled.

Paul

Thanks

After my car is driven for a while to full op temp and then parked for say 2 hours right after starting it when I give the car some rpms/blip the throttle slightly with the clutch pedal pressed I get a slight hesitation or mis. This seems to come and go and the tech at my dealer says there is nothing they can do about it. Anyone else experience this?

I also have an '07 997s and experience the same problem. I would describe it as a hesitation or lack of initial throttle response. When I use sport mode I do not seem to notice the problem.

I was also given a caymen for a loaner and it seemed even worse.

My '98 boxster never did it.

I tried switching to sport the other day right after I noticed the problem ...it unfortunately made no difference and as always went away after I drove the car for about 50 ft.

Since your car is still under warranty - I suggest you take it to the dealer and get the complaint documented.

They can read any pending codes and have a look at your car's current OBD II performance.

Certainly if you have had any "miss" there should be fault codes.

No fault codes and dealer say its a normal phenomenon and is probably fuel related which does not hold water w/ me as none of my other German cars have this issue.

Model and year of your car please...

Sorry, 07 997S Six Speed.

Did a check on a 2008 Cayenne today: no longer tyre dimensions in the menu. Looks like the last generation have no compensation anymore.

Looked today on a 08 997 GT2 - no tyre dimensions in the coding, on Cayenne 06 still tyre dimensions in the coding. It looks a question for the Harmann-Becker boys.

Thanks RFM can't wait to hear what they say.

T.P There was an item in the previous PIWIS software PCM-Navi. coding" tyre dimensions" I think it's gone now, my guess is that the standard tyre dimension be valid for the PCM distance counter. I will take a look later on this week if the "tyre dimensions" still exist.

Thanks loooking forward to a plausible explanation :)

Does the distance displayed in the PCM come from satellites?

I don't have navi...

I just spoke with one of the techs at the local P car delaership and he said Porsche (and all makes) are allowed to rest the odo up to 100 miles after they have done testing at the factory...he thinks that maybe during one of the tests, maybe the rattle test, something was heard and the car was driven back to the factory to get corrected then back over the bumps/rattle testing area until they got it right which would account for the extra miles...then they reset the odo but forgot to reset the travel function. He also said he's seen new cars come of the truck with the trip odo showing more miles than the main odo...

I'd be curious to see if anyones else's car had different #'s.

Here's how to check:

1) With ign on press the trip button on pcm

2) Go to travel data and press continuous (continuous may already be selected)

3) Compare the travel data continuous # to your odo.

Thanks.

My car's odo shows 9403 miles and the trip computer's travel data function shows total miles driven as 9430.6 along with 399:47 total hours & mins of operation etc...I wonder why there is a 27 mile difference? I was there when my car came off the truck and saw it only had 3 miles on it. Perhaps the miles were Porsche road testing and they cleared the odo but not the trip computer?

If you have a minute check it on your own cars and see what you guys get.

Thanks.

Probably a faulty sensor or bad contact on the connectors, bad sensors are not uncommon.

Thanks RFM. I hoping it's just a bad sensor and not a contact issue due to a leak.
