Chip, remap Legacy 2.0i - possible?

[phuckin]

Is it possible to improve acceleration and reduce petrol consumption by sensibly chipping/remapping a 2.0i petrol Legacy?

Any help advice very welcome!

cheers,

You may benefit a little as Subaru set the cars up to be able to deal with varying fuel qualities but I would do it in conjunction with a high flow panel filter and a less restrictive exhaust - overall power gains will be minimal though. 

[phuckin]

Thanks for that advice. Do you know of any good way to gain useful improvements in acceleration and fuel consumption, or am I on a Mission Impossible?:)

Easiest way is to drive like a granny, but that's impossible !

Is yours a n/a car ? Pretty much a waste of money for a remap as Jay says the gains would be minimal vs cost.

Try using v power or a high Ron fuel it may cost a little extra every time you fill up but I found I was getting 20mpg more in my n/a car

20? Blimey I got an extra 1 or 2 with my outback [emoji14]

Do you mean 20 miles per tank?

[stants]

Yeah sorry lol

Sorry guys but I don't know what n/a means, but it does sound as though I'll have to put up with the way it is??

[david1972]

Normally aspirated is what it stands for; in the Subaru world, essentially non-turbo charged [emoji106]

Thanks, yes mine is n/a then!

Naturally aspirated to be picky 😝😜

You could Take the cat out that's good for a few ponies other then that it starts to get expensive (turbo/supercharger) . Or paint the brake calipers red? 😉

Lowering back pressure on na can lose a bit of torque.

[JamesJDMwagon]

Louder is faster ;) on a serious not that whole back pressure on n/a is good for torque thing is only true in the lower revs like below 2k. I think engine masters on YouTube did an in depth dyno test on it. And generally removing a cat frees  up about 10-15 Bhp on a 1.6 well at least it did on my old type r engine rover (highly modified straight piped) 

[Scoobyghost]

I'm only talking from my own experience. Had a 1800 na punto(you can laugh, I do too) slapped a rude boi zorst on it and it did make 16 extra HP but dropped 10ftlb torque.

[phuckin]

Thanks for that, I'm sure there is a way but maybe not as simple as chipping a diesel engine?

[phuckin]

I'm not sure I want to go as far as removing the cat. Does anyone know what it is like to drive and run a Spec B Legacy with the LPG conversion.? I am thinking that might be an alternative.

[Tidgy]

gains vs cost simply put dont bother. subaru NA engines don't tune well cos the power is derived from the turbo. Also you can;t turbo n/a's that well because they use different compression ratio to a turbo car.

 

Save your money and when time comes buy a turbo'd one :)

[phuckin]

Sound advice I am beginning to believe. Thanks for that. I think a Spec B with an LPG conversion might be the way to go. Any thoughts?

[Tidgy]

Personally i wouldn't bother with LPG

[Jay762]

As above - I wouldnt bother with the LPG route as dependant on how you drive you still don't really gain anything, certainly not more power.

[phuckin]

Why wouldn't you? They are carried out by Subaru dealers officially now.

[stants]

I'd do the maths 1st how long your going to keep the car how many miles you do a year how much the conversion will cost and how long it will take to pay for its self

You're right, I would only consider an LPG conversion when it was on a car which was fun to drive and preferably when the car I bought already had it LPG converted.
