Well Nick, I am planning on being at Haytor Rocks car park at 11:15ish Monday June 1st, see you there!

The Porsche Car Connect app mileage display continues to annoy me. Now that my PC has reopened I've escalated the problem through their service department pointing out that others are experiencing similar issues.
I'm not optimistic as it's a 3rd party app and the service is outsourced to vodafone, both of which I'm sure will blame the other or Porsche.

The app continues to show incorrect values (even) after a run out today, so not low battery or non-recent use. BUT for the first time I have app miles = what dash value would be if it were in km! (952 app miles *1.609344 = 1,533km) Clever that!
And a better view of Haytor Rocks

Ralph / Nick,
Just thought I‘d mention that I have got the same issue with the Porsche Connect app showing the incorrect mileage for my car, despite it having its first run out today since March. As with yours, multiplying the app value by 1.609344 gives the dash mileage reading.
I was just wondering whether either of you had switched the PCM settings on the car temporarily to KM and then back to Miles to see whether the Connect App corrects itself? If not, I may experiment with this to see whether it does anything.
Given the response you have got, I see little point me contacting Vodafone and/or Porsche Connect about it, but it does seem pretty basic and must be something to do with cars standing idle for so long, as I am pretty sure mine had the correct reading pre-lockdown.

Both, if I toggle dash to km the value displayed equals the app. Exit app, ignition off, ignition on, toggle back to miles, restart app, app shows wrong mileage.
Nick, on the GB sticker, I went on into Cornwall...

Just checked mine and it is correct. Still same rev # for app. It set alarm off when I connected...
Total Trip - I reset mine to zero and it just shows mileage since reset.

I can verify that the app is displaying the correct mileage for my car as of today also. Somebody somewhere has obviously done something!
I can also confirm what Ralph has already reported - the Total Trip value via the App shows travel time / distance etc. since I last reset it in the car, so I think this is correct.
First world problems!

At least you're allowed in without quarantining.
We are hoping that those in charge of the country adopt a more workable approach to European cross border movements. I did think about telling them I was an 'elite' athlete or would be if I were able to exercise on some alpine passes or perhaps that I was importing vital supplies of French cheese and wine but then decided why come back until after summer!

Centre Gravity set up the suspension today, all OEM parts.
Actual weights with 90kg driver and 50kg full fuel were:
NSF 336kg, OSF 359kg
NSR 416kg, OSR 438kg
Total Actual = 1,549kg but DIN equivalent (no driver 90% fuel) = 1,454kg v 1,420kg Porsche website base specification so I must have extras weighing 34kg.
Cross weights 774kg v 775kg - perfect!
Front axle 45%, Rear 55%
The car is non Clubsport, iron brakes, LWB

A little more detail from yesterday:
I finally got past 1,800 miles yesterday and coincidentally I had the car booked in for a full alignment at Centre Gravity. I had run the car on track at Goodwood with 4.5k max revs so not really testing handling traits but under braking the rear was less stable than ideal, particularly so if not braking in a straight line. With social distancing I wasn't able to get under the car to have Pete talk me through the various elements, but doing the work seems to involve an hour removing and then refitting the underbody aero parts. It will be the same when the oil is changed next week, the joy of underbody aero... The car was first measured with 100% fuel and 90kg driver weight and on that basis the 'as delivered' alignment was: front camber -1:25 and -1:32 (degrees:minutes) with 0:05 and 0:08 toe. Rear camber -1:18 and -1:17 and toe 0:13 and 0:12, so pretty square. ARB factory settings were middle of three, front and rear. Ride height was reduced by 11mm and 9mm front and rear, respectively and corner weights balanced, now just 1kg cross weight difference. I prefer more camber and we ended up with -2:25 front and -1:50 rear (rear OEM TCA is still the overall constraint on camber) with 0:02 and 0:24 total toe, front and rear, respectively. The rear ARB was adjusted with one side middle and the other stiff, so slightly stiffer rear. My 200 mile journey home was 190 miles of motorway so we'll see how the new settings work up Avon Rise in a couple of weeks. Weights; my reference point is DIN, which is a base car (whatever configuration that is) + fluids which include 90% fuel. The UK Porsche site shows DIN as 1,420kg. My car was 1,549kg with 90kg driver weight and an extra 10% of fuel weighing 5kg therefore my car's DIN weight is 1454kg (1549-90-5). I must have 34kg of extra goodies. With full fuel but no 90kg driver my car would be 1459kg or 3201lbs. My car has iron brakes, not Clubsport, full bucket seats, LED lights, electric mirrors, Bose and a few other things. I would have thought the seat would save some weight v base 2-way adjustables, so I am not sure where all the extra weight over Porsche DIN has come from unless it's true that corner weight totals do not show the same (correct) weight as a properly calibrated weigh bridge.

Pleased to hear that you've passed the first stage of ownership Ralph. Now you've got the chassis sorted to your liking you can begin to enjoy the full performance of the GT4.
Interesting to hear that the rear underbody aero parts have to come off for an oil change - that's an extra hour's labour at Dealer rates ... ouch.!
Like you I'm a bit puzzled about the apparent 34kg disparity, especially given that you've got the full bucket seats which I would imagine should be significantly lighter than the standard sports seats. Maybe it's that deviated stitching? [

Hope you get some entertaining driving hours in over the summer months. I'm waiting to hear how it compares with your much-modified 3.8L 981 CS.

Jeff,
Seat weights I found somewhere in the ether, probably rennlist..
18 way (2): 128 lbs
4 way (2): 97 lbs
LWB (2): 73 lbs

LWB in name only then Ralph, especially when you consider that the Sabelt seat in the Renault Alpine is only 13.1kg, including the seat rail.
I suppose every option adds weight, and I think that the bi-xenon and LED PDLS headlights are quite heavy compared with the standard items. I think Porsche are pretty honest when it comes to quoting figures, so you have to believe their DIN weight.

Ralph,
Regarding your comment on the rear axle being less stable under braking, may I suggest you try a different rear total toe setting.
In my experience Caymans work well with minimum toe on the rear axle. Your rear total total toe setting of 0.24" is on the high side. I've found a maximum total toe on the rear of 0.16" 0 0.18" suits the Cayman ideally, for my tidy driving style anyway. Too much toe on the rear, or too little, will induce a squirming effect under heavy braking or acceleration.
In my experience with a myriad of different settings, zero total toe on the front axle, and a maximum of 0.18" total toe on the rear provides perfect balance between braking and acceleration on the Cayman. I ran my 718 GTS with both 0.16" - 0.18" total rear toe. It worked well.
Just my tuppence worth.
