So after you pull both paddles back to find neutral; do you just pull right paddle back one time to go back to first ?

Pull either paddle once and you will go back into appropriate gear for your speed, not necessarily 1st gear.

I believe the manual says that if your speed is near 0, you have to apply break pressure at same time as paddle flick to get back into gear.... Presumably a safety feature.

Learned something changing oil the other day. Make sure the 8mm hex key is all the way in the oil drain plug when torquing it down or you'll spin the key in that soft aluminum. Then you need a new drain plug with crush washer and a "multi-spline extractor" to remove the old one (everything is a piece of cake with the right tool).

Good tip! Learned this one the hard way...now I'm just changing out the plug when I change oil too! Bought extras from Pelican. About $2.50 each.

Car wash note: Don't blast underneath the engine area if your car is hot. Hot headers and cold water is a no no.
That's relieving to hear :P

I have a GTS. I was driving in 95 degree weather a few weeks ago in normal mode. I notice the oil temp started to rise fairly high, up to 230 degrees (normal is around 200). I thought it might be the A/C putting stress on the engine, so I turned it off and the temp didn't move. I then left the A/C off and turn Sport on, the temp drops to 210 in 5min. I then turn the A/C on and left sport on, the temp kept dropping to 200.

My hypothesis was the car runs cooler in Sport/Sport+. I did research and it's confirmed that if your car has a 3rd (center) radiator, turning on Sport/Sport+ opens up that 3rd radiator. For cars w/o the 3rd radiator, it stills runs hotter in normal mode for maximum combustion efficiency (fuel economy). This also means don't turn on Sport/Sport+ in the winter as it may take longer to warm up.

Cheers.

Please share your random discoveries...
Every 991 has a water-to-oil intercooler mounted above the engine. It opens to provide additional cooling when Sport or Sport Plus is pressed and drops the oil temp ~20 degrees. The third radiator works independently to keep coolent ("water") temps down.

I realized i lose the rev matching feature (throttle blip) when the traction control is turned off. Silly.

Is the third radiator for coolant in the front "open" all the time or is it switched on and off in series/parallel with the other two up front?

I have been pleasantly surprised by how my 991.1 GTS cab has gotten throatier with "age." It has about 9,000 miles (got it in October). Somewhere after 2,000 it really seemed to find its voice throughout the rev range, including on ignition. I did not find this to be the case with my prior 991.1 (C2 cab). Perhaps it is a placebo effect and I am hearing things but I don't think so.

When slowly creeping to a stop with the PDK (Mine is usually in manual mode), you can quickly blip the gas pedal and the car won't go faster. You get to hear the beautiful exhaust tone!

For you PDK people you may not know this and may not care but...in the manual tranny cars if you give it too much clutch and kill the engine all you have to do is push in the clutch and the engine restarts. You don't have to touch the key at all.

That's a good tip. Very cool.

Now's that's amazing. 991.1 or 991.2? I haven't drove in "normal" mode for more than 5min yet, so MPG is poor.
