June 18, 20169 yr 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, Philip Huckin
June 18, 20169 yr 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.
June 18, 20169 yr Author 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?:)
June 19, 20169 yr 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 Sent from my SM-G930F using Tapatalk
June 19, 20169 yr 20? Blimey I got an extra 1 or 2 with my outback [emoji14] Sent from my iPhone using Tapatalk Do you mean 20 miles per tank?
June 19, 20169 yr Author 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??
June 19, 20169 yr Normally aspirated is what it stands for; in the Subaru world, essentially non-turbo charged [emoji106] Sent from my iPhone using Tapatalk
June 19, 20169 yr 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? 😉
June 19, 20169 yr 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)
June 20, 20169 yr 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.
June 20, 20169 yr Author Thanks for that, I'm sure there is a way but maybe not as simple as chipping a diesel engine?
June 20, 20169 yr Author 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.
June 21, 20169 yr 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 :)
June 21, 20169 yr Author 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?
June 21, 20169 yr 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.
June 21, 20169 yr 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 Sent from my SM-G930F using Tapatalk
June 21, 20169 yr Author 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.
