remap for 95ron???
I have a standard 1995 wrx, If i was to get it remapped to run on 95ron fuel what sort of power could i expect?
Is it currently supposed to be 260hp?
The reason i ask is because its a pita getting super fuel where i live
The only mods its got is a full decat exhaust.

1995 WRX Import is 240bhp or there abouts, if it's a UK then it'll be about 215bhp. Have you got a mappable ecu, as the standard one cannot be mapped?
Power wise you should see 280bhp on 95 ron I would think if its a saloon, but your injectors won't do any more than that, so thats really your limiting factor.

Cheers. I realise that i cannot map my ecu as is, What would be the best way to get a remapped ecu and price? Im not really fussed about loads more power im more interested in being able to run it on 95ron fuel. i have got a spare ecu apparently fitted with a chip but dont know what it was mapped for.

I was looking at getting my 06 wrx remapped to 95. It's running 334bhp and 381lb/ft torque now on Tesco 99. The 99 is getting more difficult to get hold of now and there was a thread on here discussing how it might be getting phased out.
Any idea what sort of power and torque difference and loss I would expect? Also, will it be more likely to det in lower octane stuff?
Thanks in advance and sorry to hijack your thread.

Best way to make your car remappable is either with an ESL daughterboard, £550+vat includes fitting and dyno tuning from me, or something after market like an Apexi, (second hand only), or a Simtek ECU £960 incl vat and mapping.

I had my simtec mapped for 95 ron and second map on v power the difference was 17 bhp.
When i get round to modding my new car i will put the cheapest nastiest 95 ron i can find in it and have it mapped on that and if it costs me 25 bhp i won't care as the hastle and cost involved in price of fuel as well as looking for it is not worth the 17 bhp difference.

Sorry for the thread hijack again, but had a thought I wanted to ask Graham.
Obviously if you have the car mapped on 99 and run on 97 or 95 you risk det and damage to the engine.
If you have the car mapped for 95 can you still use 97 and 99 without having to worry? Also, Would you see a minimal power increase running 99 on a 95 map?
Thanks in advance.

So you have your car remapped at a cost of 500 quid, the difference between 95 and 99 is 3p? you fill up 60ltrs every 2 weeks, thats £1.80, times that by 26 = £34.60? so per year thats how much extra you would have to pay, now note that you would need a good 10 years to break even, its not worth it.

Every 2 weeks? We obviously don’t do the same mileage then! My car is an every day car, gets used a lot, filled up every week at least.
Trouble is, 99 is getting much much more difficult to get hold of. I have to drive quite a way now to get it as some of the local stations have stopped selling it. That’s the main problem!
So yes, I am considering getting car re-re-mapped! Say what you like, will make my life a hell of a lot easier!

Its not down to price, never has been. When your paying £480 a year tax and Christ knows what on insurance then I cant say I have ever had a problem with spending. If you car about how much it will cost you to run then you cant afford to run it.

Even then you would need 5 years to break even, and I dont have that 480 tax bracket to pay (import ) so its still not worth it tbh, and just look around for fuel, more than enough available in oxfordshire 99/v power

Besides, not £500 for re-remap, is a lot cheaper for a tweek!
I always use the 99 stuff, hate putting anything else in it, just becoming a right pain to find (outside of Oxfordshire) these days.
Completely agree though, if your looking to re-map it for 95 to save money then its completely pointless!

9 miles to my nearest shell or tesco, so 18 miles to fill up. 1 gallon or £6 petrol wasted, plus 8p a litre more than 95 ron.
so, if i remap to 95ron, i'll save £4 on the fill up and £6 not wasting fuel, so £10 per tank
so, £50 for a map tweek will pay for it's self in 5 full tanks
