wot engin????

[wilky]

hi folks, im new to the site and the world of leons. im goin to buy one in bout 3months when i get the money up. i can only afford to insure either the 1.4petrol or the 1.9tdi (90) due to my age and cos i live in n.ireland. wot 1 shud i go 4?

 

[acidstrato]

the diesel

then get it remapped

 

[wilky]

wot advantage will getting it remaped do. ive also heard of gettin it chipped. whats this and is it an advantage

Remapped and Chipped are two different ways of saying the same thing. If you're picky, remapping means overwriting the existing ECU data with a new code and chipping means replacing the physical chip(s) on the ECU. But overall they aim to achieve the same thing.

What do they do? Well in a nutshell, they increase power and torque. The ECU code is changed in various ways to extract more power from the engine, usually by increasing fuelling and boost as well as tinkering with ignition timing. It's a big subject!

Well worth doing though without a doubt.

And to answer your original question... get the diesel.

brilliant. thanks lads. wot bout fuel consumption when gettin it remapped

roughly the same although can improve as you use less throttle to do the same speeds. unlikely that you'll see much difference though

is it not your gear ratios that depend on what throttle is needed to do a certain speed?

 

[Reg]

Your gear ratios govern what speed you do for a given engine speed, not throttle opening. For example, in 4th gear at 3k revs, you might be doing 60mph. Whatever you do to the engine, you'll always be doing 60mph at 3k in 4th - whether you have 100bhp or 1000bhp.

The difference is that with increased torque, you don't have to have the throttle open as much to maintain that steady 3k revs. So if you are depressing the accelerator 10% less, you will be using less fuel. Or, the engine will happily pull a higher gear for the same speed. Again, for example, before a remap your car might struggle to comfortably drive at 40mph in 6th gear, so you have to drive it in 5th, or even 4th. Once remapped, the extra torque will mean you can leave it in 5th or 6th, so its doing less revs at the same speed.

thats not how it was meant to be taken

thats a better explaination sorry for the confusion

basically you wont need to push the car as much for the same rate so fuel consumption will be reduced.

I'd go for the diesel, feel much more torquey than the petrol

 

[wilky]

brilliant lads. ill keep u posted when i get it
