Are you guys talking about it holding slightly high revs when you do a cold-start? Like 1400rpm for a minute or two? My old XJR does that, I think most modern cars do it...

 

Yes, I'm still in total agreement with Foosh on this one. I got a similar result when warm starting not long after a previous shut off, which made me think we were on to something, but the technique was never reproducible on cold start.

 

I think the question/comment was how to have a less "dramatic" (using TahoeDave's word) start. In other words a quieter start. I'll give it a try later this morning...not that I have any qualms about my dramatic start.

UPDATE: Started the car this morning...business as usual. Nothing quiet about it. Loving every minute of it Jerry.

 

To build on Jay's response a bit, it is not the extended 1400 rpm warm-up that is being referred to, but rather the instantaneous automatic throttle blip to 2500-3000 rpm with open baffles that occurs immediately upon start-up.

 

BTW, that was a cold start. Last time the car was started before that was Monday.

 

Mine too. Not questioning your personal experience - your You Tube clip is proof it worked for you - or DJS's, but based on mine, put me in the debunked camp.

 

Well, then apparently your car is very unique. The only thing I can think of is that your ECU was re-flashed at some point, with a different version of the software.

 

As we posted when it was first suggested, it doesn't work with a genuinely cold start. If the car is warm or has been started a few minutes prior, the next start is quiet(er). That's easily reproducible. Nothing seems to quiet a start when the car is properly cold or hasn't been started for a while.

Edit - I popped into the office this morning and just tested this again when starting to head home. Same result. The car was as loud for the initial when using the technique described and quieter on a subsequent restart.

 

so is it normal for the engine to hold 1400rpm for a min or two for start up. Should I wait during this time and let it rev? My car has done this a few times, I think sometimes it even goes to around 2000rpm.

thanks

 

Yes, normal. Many modern cars do this now for a faster warm-up.

 

So should I wait for the car to go back down to idle? Or it doesnt matter?

 

There are two issues being discussed in this thread. First, is the start up blip where the engine immediately runs up to probably 2500 rpms and throttles back very quickly. After that, it has a faster idle for a short period of time as I think you're describing.

It's OK to put it in gear and go during the fast idle. Just putting it in gear will throttle it back.

 

In generally, it usually takes about 30 seconds for a complete oil cycle on a vehicle. As long as you give it that amount of time (which is about the amount of time the increase idle lasts), you are fine to go into gear and start driving.

Can you do it before then? Yes and it likely won't be a problem. However, I tend to stay with the 30-45 second rule just to be easy on my cars.

 

Agree here on this to me no issue at all

Weird trick. That maybe I’m hallucinating. Leave it in dynamic mode. That way when it starts up. Atleast to me in my 2015 R it’s strangely quieter.

will post video when I get car back in a week or so.

 

I don't remember what the update code was, there was thread about here and a few members weren’t too happy with the update and I was one them initially. The only reason why I found out about the update because I started noticing the car was reverting to normal mode even if it’s in dynamic mode when I turned the car off and it wasn’t like that before I brought it to the dealer to be serviced, if the car was on dynamic mode when I turned it off it would still be in dynamic when I started for at least a couple of hours later. It might even be longer I can’t remember, it’s whenever the car went to sleep mode, i think thats when it resets back the default normal mode. It makes sense if they’re trying to lower the db levels at start up. when it’s in normal mode the exhaust valves closed and is not as loud as when it’s in dynamic with active exhaust valves open. Apparently JLR felt there was enough demand/complaints and they needed to do something about it and if i recall correctly it started in europe and then came to the North America.
You should check with your JLR service about getting the update if it hasn't been done and maybe it will be quiet enough for you and your neighbors and everyone’s happy and it would be one less problem you have about your ftype. I think I speak for everyone on this but most of the people that get into an FType knows about the much louder than the normal exhaust whether its a v6 or an 8 Ftypes are known for its exhaust notes and as you put it “the dramatics” its what gives the car character, its part of the design it is what it is and you either accept it with all its quirks and or you don’t. It doesn't matter what anyone else or what the neighbors think or feel about your car and at the end of the day the only thing that should matter is how you feel when you’re driving the car. Are you excited and does the car make feel more alive and want to drive the car like you stole it and the loud exhaust does draw attention, good and bad but it comes with the territory when you own and drive an FType and if you can’t accept and deal with it, maybe it’s time to consider driving something else maybe something that doesn’t draw attention and blends with the crowd and something quieter perhaps a Prius or a Nissan Leaf .

 

6 hours was the stated time that it would stay active, and een after the update the car still remembers the mode - it just resets when you switch on. You can verify that by seeing the red ambient lighting when you get in the car.
