Mapping out the cold start

[Noam]

Is this really necesary on a catless , or even car with CAT car?
Is there anyway to shorten those 2 min. of cold starts?
Thanks

When an engine is cold, it runs better with a rich mixture (more fuel, less air). Years ago, the choke pinched off the airflow to the cylinder (hence the name "choke") and was operated manually. Later it was operated automatically (often turning off too soon and causing the car to stall a few minutes after starting). In modern cars, there is no choke, just the computer controlling the fuel and air mixture on a moment-by-moment basis.

Surely the cold start system is there to help the car run when its "cold"!
I dont understand why you would want it removed ?

I was more under the impression that it was mainly to warm the CAT and ready it for proper emissions efficency.
Maybe the length of it could be shortened to half the time??
I just sit and wait it out , as driving at 1100 RPM gives an uneven feeling to the initial 2 min. drive . So more an annoyance thing

Just have to deal with it im afraid, its about whats best for the car and engine that matters, to me anyway. I can deal with a few mins of 1100rpm and gentle driving to make sure i dont damage the engine!

 

[mr_D]

yeah i dont get that! Why are you annoyed? What reason have you got to hate the cold start? Do you get really pee'd off quickly. I have never ever ever thought of the cold start being a problem.

have to wait a while anyway for the turbo to warm if you wanna have a proper thrash. No good ragging a cold engine/turbo.

also, I dunno about you, but it takes me abut 2 mins to get off my estate. Or are you one of these people that likes to race around housing estates?

i know this may sound a bit stupid, but your engine isn't going to warm up that quickly whether or not you have the cold start on or off is it? it's still gonna take a while for the heat from the combustion to warm the rest of the engine up etc. isnt it???

I know all that and for 8 years I've never even gone over 3500 rpm before oil temp. reaches 90c , so don't try to assume or pick a fight !!

 

[Fl@pper]

if you did remove it you'd end up with 10 mins of stalling and/or slipping the clutch keeping it revving higher just to move

its a minor inconvenience and not one that's on and off as it works on a sliding scale from the temp sensor

Thanks Flapper

Are you looking at the temp gauge on your dash or have you got an oil temp gauge installed?

If you are looking at the dash then thats coolant temp, so more than likely the oil wont be at the same temp as this. I know mines isnt when it reaches 90c. Get an oil temp gauge if you want to make sure.

No-one is trying to pick a fight, people just cant understand why you want this removed so badly. As all the reasons people have said.

But if you do want it removed, then im sure you'll manage to find a way but just remember to keep a bit of money back for all the parts which may get damaged and need replacing/repairing.

Another assumer I guess Ross . .
I have am oil temp. gauge.

 

[cupramillo]

Until people know the facts thats all they can do assume....no one is picking, just trying to understand why you want to remove the cold start, something VAG probably spent millions of pounds developing for the saftey of the car... thats all

 

[Noam]

I deal and will deal too .
It's just waiting with a loud zorst every morning or after leaving car cold in the winter is somewhat annoying . At least it gives me time to annoy my pain in the ass neighbour . .LOL

Just think about the replies that you have had from people with experience on the forum, and its upto you if you want to take heed of what they've said. I know i would
