Title: remap / chip
Post by: Mark b on 25 July 2014, 18:35
ive a 2.0 gti non turbo and just got back from a remap place near me so I can go from 115bhp to 128bhp with that increase would I feel much difference

Only one way to find out......

On N/A cars a remap helps fill out the lack of torque at the bottom end and make the car that little bit sharper overall

Said it before in previous threads you have asked it's a 2.0 sadly they are sh!t either make it look tidy or buy a 1.8t simples

Doubt you would gain that much power tbh 3/4 bhp is about normal on a n/a car.

I disagree

I think you lot get hung up on PEAK power figures and forget about AVERAGE bhp gains which can be quite a difference

13bhp still seems lot from just a remap on a non turbo car  :undecided:

it was the same with my 4mo it never gained much bhp but it did drive ten times better getting rid of any flat spots it had  :smiley:

Power is basically proportional to how much air the engine is breathing. Which is defined by the geometry and valve overlap. In cars with variable valve lift and overlap, you can reasonably alter it to change how well the engine breathes at different points along the rev range, and therefore power.

The 2.0 doesn't have any of that, it's fixed geometry and timing. So what exactly is one supposed to 'tune' to gain anything beyond minor alterations in fuelling.


Most N/A tunes involve raising the rev limiter to eek out the extra top end power, and a smoother fuelling map.

You can get 7-10bhp out of a 1.2 Corsa  :grin:

And 60bhp out of a C63 AMG  :evil: :smug:

Respect that but most remaps I have seen on standard n/a car have only seen a maximum of around 7bhp, 2.0 Golf has to be one of VW's worst engines in the mk4 so whilst it will make it a smoother etc I still doubt it is going to add 13bhp.

I didnt say it would make 13bhp

And are you talking about peak power or average power gains???

If you can't make an xhp gain at the peak (or top end), you can't realistically make a xhp average gain.

Unless you have a very strange definition of average, or you are splitting the curve up into broad sections.
Or you mean % gain.


EDIT: I'm not saying you are wrong in principle. I actually agree with you that it's the curve that matters rather than a peak figure. But high peak figures allow for much willy waving.

You want the most power, where you use power. Which for most people is sub 3000rpm.

the bloke said to me id notice the difference more in higher gears

Thats the way I think and its how I market my remaps  :smiley:

Do you want good, usable power across the rev range or a million BHP over the last 500rpm?

Peak bhp doesnt necessarily make for the quicker car  :wink:

That Corsa I did the other week, the bloke could feel the difference in the first 3 gears within just a few hundred yards

Again like a few others have said a remap done properly makes for a much nicer drive  :smiley:

It will be smoother but don't expect it to wow you mate in all honesty for £250 or how much it will cost I think it would be a waste of money difference on something like an r32 it's totally changes the car.
On a 2.0 it will be minimal!!

And let's be honest he's not going to tell u it's sh!t is he he will want business

That IMO defeats the object. You want the difference pulling away and getting up to speed

Yup I love the mid range area on my graph :afro:

Exactly. Especially where you live; a big top end is pointless  :laugh: :kiss:

Post by: xxChrisxx on 29 July 2014, 22:05
To be fair I think most people don't consider low and midrange power until they don't have it anymore.

My main driver is now a 325i. N/A 6pot feels great when you are driving it properly, but the lack of low down grunt can be a massive pain in the arse at times.
