You must have a PDK?

 

He mentioned having a ‘23 MT Carrera T.

 

M3 is right 7-sp MT 992 CT

 

I spoke with Scott and I was very impressed. Unpretentious professional, running solid business.

Scott, thanks for taking the time to share your knowledge and experience.

I will have to upgrade my 992 with the Softonic mapping and experience what this car is capable of . . . I just need to nurse my injury first, so that I can drive again.

I will also have to look into brakes upgrade to preserve the golden ratio of acceleration to stopping power. But that is a separate/parallel discussion.

 

He is a class act for sure. Looking forward to following your modification journey.

 

Having not read 13 pages of posts completely, I'm not sure if this is covered, but I see that on the Softronic site he specifically mentions NOT eliminating cold start, while I know that is a feature available and often selected with those who opt for M-engineering's Coder/Tuner.

Scott's site says he can, but recommends against.

Curious why?

 

He mentioned benefits of the cold start process and related engine longevity due to the lubrication that occurs during cold start.

 

Cold start serves multiple functions, including preheating the cats, ensuring adequate oil pressure, and initiating the heating cycle of the engine oil. For me, that last point is perhaps the most important. Engine oil serves a very critical role beyond simple lubricity, and brining it up to operating temperature before placing the engine under a load, is one of the best things an operator can do for the longevity of their car. There are other considerations regarding the lubricity of fuel, challenges with horizontal cylinders, and direct injectors, but discussion's around that subject tend to devolve into bickering.

 

You are going to want cat preheating if you do/plan to run sport cats, they need to get up to temp to not trigger a CEL.

 

My understanding is that temp needs to be above 180 before putting the car above 4000 rpms as a general guideline and that even with a cold start, the car won't approach that temperature for at least a few miles. One would be sitting there for 5-10 minutes waiting on adequate temp and that cold start high throttle drops long before ideal temp is reached.

Does cold start suggest one does not move the vehicle until after the completion of the 90 second cold start routine. It's not physically possible to drive it without breaking the cold start rpm and as a result placing the engine under a load greater than the cold start routine.

 

I have always waiting to drive away until the idle kicks-down.

 

Go to Scott’s website and read the FAQ’s. He provides an excellent explanation along the lines of cavemanmoore’s well reasoned post above. The reason many eliminate cold start is to keep the wife and neighbors from bitching when you crank it up at 6am with sport cats and muffler delete exhaust.

 

Your reference to 180 degrees seems to be about engine coolant temp. I'm referring to engine oil temperature. I didn't mean to imply that one needed to let the car reach a certain temperature prior to operation, but rather that it's sensible to reach optimal engine oil temperature before placing the engine under heavy load. I usually let my car run through the pre-heat cycle, then allow it to reach optimal temps under normal driving conditions–limiting hard acceleration until the engine oil up to temp.

Yep, me too.

 

Really not needed, link ...the car warms up faster when not idling...

 

Fast idle stops once car is in motion.
