Can you change the cold start features of the c8?

If i cold start the car, then open the trunk / frunk the engine stops, how do i stop this from happening?

 

You can't disable that, its a safety "feature" much like how a normal car will cut the engine if you remote start then pop the hood.

 

It works fine on my Redeye, i guess Dodge is old school

 

I would not disagree with that! To pump out the Hellcats & Demons they keep those lawyers on a pretty tight leash apparently!

 

Where is the switch that monitors hatch position? Gotta be a way to bypass it.

Hmm, have not started my car remotely in 18 months and have no intension of doing that!

Can understand Daughter on NE OH who uses it when temps are below freezing when leaving work but in NE SC, although it gets hot if parked in the sun, can live with a few minutes of heat! Never gets cold enough in winter to consider!

Just don't understand the "big deal!"

 

Having heard both on cold start, the C8 Stingray, with performance exhaust, sounds just as good as a C8z06

I use Remote Start all the time, to enjoy the sound.... even at the local Porsche dealership they were impressed!.

 

Remote start the car, get in the car with the fob. With foot on brake, press the start button. Then you can pop the hood without the engine shutting down.

 

I agree, I love to hear it cold start. Also, it buys me some additional time to get the engine up to temp before I engage into gear, which I am OCD about.

 

Reminds me of my wife who is from NE OH and was taught you had to let the car warm up before you drive. Yep we're both '79 and back in the day cars had carburetors and the mechanical coke system make the air/fuel mixture rich with gasoline that went past the rings etc. Took time for that mechanical choke to warm and allow the car to idle at a lower rpm. Oils were often a fixed viscosity and were somewhat thick at colder temps (although a 1 or 2 minute warm up did little to thin it out!)

Today with fuel injection especially the DI where fuel is injected in a very fine mist into compressed air before a spark plug ignites and that "warm up" is not needed! It's a waste of gas AND causes more pollution.

Quoting a reference answering he question is a warm-up needed: "Only carburetor-equipped engines — without injectors, these engines run better once the “blood” starts flowing. Manufacturers today design vehicles with utmost efficiency in mind. So warming up your newer car in the winter is a waste of gas."

Also a short warm-up does little to heat the oil. That viscosity decreases little in a minute or two. Today manufactures use multi-viscosity oils like the C8s 0W40. It's like a 0 weight oil when you start. BUT still IT IS Important before using significant power to have the oil up to temperature- hot. The C8 helps by posting a red area above 3000 to 4000 rpm in the tac until the oil is warm/hot. I watched the tach and in my manual cars (all for 60 years before my C8) and "short shifted" until the oil was hot. In fact my C8 left dash display shows, Transmission, Oil and Coolant temps and those are my key indicators.

For example, valve springs are by far the most highly stressed parts of a high performance engine. Before hitting redline I make sure the oil is past 175 F. a one to 5 minute warm-up does little! Quoting: "Valve springs are the most highly stressed engine part. Just how much torture are we looking at? To put things in perspective high-tech connecting rods with a 250,000-psi tensile strength. the rod "rarely sees even 50,000 psi of stress under real-world operating conditions" (20 percent of its rated load, or a 4:1 safety margin). But it's common for a valve spring to continually operate at half or slightly more than half of its rated load. "A spring that's rated at 300,000 psi routinely will see loads approaching 150,000 to 190,000 psi every cycle." (To put that strength in perspective, the steel bridge you go over has steel with a tensile strength of ~50,000 psi or less. Also although springs are stressed even at low rpm near redline the added harmonics as the valve seats increases stress)

Now all that said I'll never convince my wife she can just drive off without "warming the car up for a few minutes!" Expect this will not convince many who will believe what they want! Or worse some who think their few minute warm-up before driving means that can use WOT before the engine oil is up to 175F or higher!

 

Jerry if that’s all true do you get into your car slam the accelerator to the floor and hammer the car or do you let it come up to temperature before your exercise the car? Each to their own but when I was in Ohio in the cold I too took your wife’s approach and would today.

I know my posts are long and few read them (glad some of the Silent Majority do and send PMs or emails thanking me so I continue!)

BUT I clearly said I wait until the engine oil is up to temperature before I use significant power. That takes quite a while. I presented that valve springs, particularly in a high performance car iike the C8, can use 300,000 psi strength steel. Gave a comparison that a steel bridge uses only ~50,000 psi strength steel. Steel has a property (unlike say aluminum) where at cold temps it can be as brittle as glass! The stronger the steel that brittle/ductile transition can be quite high MUCH higher then a few minute warm up will achieve. I said I will not get near redline unless the oil temp (which I monitor) is past 175F! NOT coolant temp which gets hot quicker.

Nope I don't wait even 30 seconds before I drive BUT would never use significant power until the oil is ~175F or higher. I have Oil, Trans and Coolant temp displayed on the left side of the dash! Yep a little Metallurgy 101 with these posts!

Some ship failures were attributed to brittle steel (like WWII Liberty Ships and perhaps the Titanic)

Warm the oil, drive it like you stole it, never had a problem in 40 years

Its not an F1 engine.

 

I have found that you can open the frunk after remote starting and it will not shut off the engine. However the rear trunk will. Strange the lawyers let that one get by.

 

The frunk doesn't give you access to the engine compartment. On front-engine cars, you can generally open the trunk after a remote start, but not the hood.

 

@JerryU
As a structural steel fabricator, I understand "charpy v notch" testing. Just like you, I will not punch the throttle until all fluids have come up to "operating temp", same with tires...
