Technical Red Line?

[OCZedd]

I have pondered on this often,so you`re not alone asking this question.
My GP (1.4 Sporting),will happily rev to 6500 with no apparent problem,and there seems to be no rev limiter cutting in. I don`t think revving a petrol engine to high revs does any damage and is probably healthier for the engine than constantly driving at low revs,otherwise known as driving like an old woman.

Hmm, why would it be healthier to rev it lots. I am guessing not when its cold.

Dont rev it past like 3k untill its properly warmed up. After that it shouldnt do it any harm taking it to the red line.

If there was one lol

 

[punto_matt]

There is its 6.5k. Try reving past that and the engine just stops revving

If there was one lol

there is

we have the same car

Thats not a redline, thats a rev limiter. On a 1.2 active there is no red line, thats what the OP asked about.

if you read,

they say about the dials not showing it. and therefore ask what revs it hits the limiter

stop being petty and trying to cause an argument.

They are basically the same. The red line will start at 6000 if the clocks were coloured in red and would finish at 6.5 when it hit the rev limiter.

I'm not being petty and trying to cause an argument. I am just saying a redline is not a rev limiter. And I would like to know what a redline is in the 1.2 Active.

Where did you get 6000 from?

:bang::bang::bang:

 

[punto_matt]

What do you mean where did i get 6000 from?

 

[OCZedd]

You said the redline would start at 6k and end at 6.5k (the limiter) how do you know this? Because mine is white lines all the way to 7k.

Also I am not trying to start an argument I am just asking a question.

 

[punto_matt]

i dont but im thinking logically. Ring up fiat and ask them if your really that bothered about it.

 

[OCZedd]

Alrite no probs, I just thought you actually knew it from somewhere. I guess it doesnt matter that much, i rarely go aboue 4.5k normally.

Sorry,forgot to mention I let her warm up well before going over 4k. I have read it somewhere that engines unused to highish revs develop a ridge on the cylinder bore.
This kind of driving also tends to lead to carboning and other bad side effects. Some mechs. just take a car on the road and give it a good burn-up for a few miles if they know the car has been driven slowly (Italian tune-up).
Don`t forget it`s an Italian engine and has been built to be revved hard.After all,that`s how the Italians drive them.

 

[OCZedd]

Yeah I see, hehe well I should know, they do.

i have learnt that:

if you drive it at low revs it the ecu will get used to this and change the way it fuels and the engine wont drive the same as mine (which does get revved) mine goes up to the 6.5k limiter no problem in 1st,2nd,3rd but yours may not if it is never taken above 4.5k like you have said.

i believe that the ecu learns every 400miles on the way the car is being driven. i have experienced this in my dads old stilo when he has been doing a lot of motorway driving it would rev around to 6750rpm no problem but if it had been going around town for a while and not really being revved then it would only hit 6250rpm then the limited would come in.

not sure if this is the same as new cars but it was only an 02 reg so it could still be the same

please correct me the people that are more educated than me i'm just speaking from my own experience

 

[OCZedd]

Wow, thats sounds pretty cool that it changes the rev limiter depending on the ECU's data. Oh and I said I don't go above 4.5k in normal driving. But when I get onto carriage ways and bigger roads I give it some, to about 5.5k (no point in going over as this is peak bhp).

i may be wrong but thats what i've noticed

 

[punto_matt]

The ECU relearns when it is reset. When it has been reset you should keep the revs below 4000rpm for 20miles so that the engine can map itself for the higher rev range. If you hammer it from the go then it is likely to run lean in higher revs.

That is for a mk2 1.2 8v engine so i dont know if it would be any different for the GP engine. I dont think it would though.
