FTO AUSTRALIA

I'm getting her serviced on the weekend but thought I'd pose the question here first. In the first say 10 minutes of driving, the rev limiter on my FTO occasionally kicks in at totally the wrong location. An example being last night, I pulled out of my driveway, floored it in first and the rev limiter kicked in at 5000 revs!!! Of course the engine isn't even working at that point. After the first 10 minutes, it never happens and she'll happily rev right rough past 8000 revs.
I can't see this being related to the stepper motor (which was causing the odd idle problem but seems to have stopped now) and I'm sure it's the rev limiter, there's no mistaking it.
Anyone experienced this or got any suggestions?

the ECU limits your rpm while the engine is still warming up so you dont damage the engine.... once its warm, it lets you rev out to your normal limiter...

There's a cold start rpm cutoff at 6k rpm which also disables MIVEC if you have it.

This same mode occurs when one of your important but not critical sensors fails.

Moral of the story, don't floor your car as soon as you start it =)

Ahhh, isn't that clever
So how long, all things being equal, does it take for the car to reach operating temperature?
And what "non critical" sensors create the behaviour.
And most importantly, does the forum stop branding me as a "Newbie" when I stop asking stupid questions like this?

normally allow 10 minutes (or more) before really "driving" your car..

i always give me a warmup before driving it when its cold... normally the length of a cigarette then drive it slowly for the next 5-10minutes (i.e. not above 3500-4000rpm)

hahah its based on how many posts youve made i think... even though ive been a member for ages, i was a newbie for most of it because i didnt post much until recently

LOL!

The "newbie" status has more to do with your longevity and the number of messages you have posted on this forum.

We go gentle on the newbies so as to not scare them off!

As a newbie however, it is worth learning about the " Search" button located at the top of this forum as you'll find that most of the questions "newbies" ask have already been asked by other "newbies" who joined the forum before them. As such most of the answers are already on this forum along with a wealth of additional information you may not have thought of.

But we were all newbies once, so don't fear about asking, at worse we'll just point you to this "training video" that Twistea found

Oh, and remember, there is no such thing as a stupid question, so ask away.

lol missed this the first time ... its post based and its something like 100 for n00bs....


oh there's no limit on the number of dumb questions you can ask

Gee, I never had to worry about taking it easy with my Hyundai Excel

Now I just have to think of some more posts and/or stupid questions to up my postings count

you don't have to take it easy... but they're expensive to fix

Eek! No! Be gentle, boyo!!!

mmm generally when the little tempreture sits in the middle of cold and hot u no... the one in the dash between the speedo and revs

Well, normally you wait for a bit longer, as the oil takes more time to get to operating temperature then your coolant.

I've stalled my car before by thrashing it while it was cold. Just left work and hammered the car in an attempt to make a set of lights. Didn't make it and my car stalled at the lights. Quite funny when I think bout it now.

Yeah... Think 10 minutes driving for oil temp to get over 50 degrees C, as opposed to 2 minutes driving for the coolant temp gauge to get into the middle.

The oil temp gauge I added to my FTO will have added years onto the expected operational lifespan of the engine!!!

yeah that'll be a dirty stepper motor doing that... when you drive it hard it confuses the hell out of the ECU...

Found this article on installing an oil temperature guage but more importantly it gives a time frame of up to 15 minutes for the oil to reach operating temperature and thus a good indication of how long you/I should wait before trying to engage MIVEC.

LOL!
That article is by RichardH (look 3 posts above).

So Richard, was that 15mins idleing or 15 minutes driving?

As per previous discussions, an engine warms up faster under load (driving), and I would have thought that 10min of driving (under 5,000rpm) would have been enough to get the oil to a safe temperature.

I want to fit an oil temperature guage but my clock has already been removed and a vaccum guage installed in it's place. An oil temperature guage would be so much more useful...I think.

hehe. Yes, my words coming back to haunt me.

It depends on how bl***y cold it was overnight, hehe. If you head off on a cold cold morning, tootling around quietly, it can take a good 15 minutes to get over 80 degrees.

80 degrees is being pretty conservative, I know. But why thrash around on cold tyres, with cold gearbox oil, and tepid engine oil, eh?
