how much would this cost for an import WRX MY95 and where in the Newcastle area could i get this done?

 

Not 100% sure about a place in Newcastle, there are no garages which are raved about up there to my knowledge unless someone knows different.

If however you chose to travel a bit, and get the job done by renowned people, someone like PowerEngineering or the like, basically someone who will fit an ECUTEK ECU to your car, and will map it for a chosen fuel....this will cost around £800 I think. Will give 260 odd bhp though and 260lbft torque with everything tailing off properly towards high revs to save engine.

 

ECUtek is a no go for that age of car.... Running the car on Optimax you should be ok as long as your not running silly boost. You could get a scoobyecu which is a plug in chip that could increase the boost to about 16psi and alter the fual and ignition to suit. Speak to David Wallis or Paul (Pavlo) for the low down.

nah i was just trying to save money and not spend any on octane booster but it looks like i will have to!

 

Oops didn't realise that, I thought ECUTEK I was for pre97 cars ? ECU TEK II for post 97 ?

 

You could try AS Performance based in Birtley, as-performance.co.uk
Tsunami Racing, Saltmeadows Rd, Gateshead, tsunamiracing.co.uk
R+P Woods in Heaton supply Superchips(eurgh!) and have a rolling road but I don't know if they are able to MAP Scoobies

 

Ritchie do you use OB? if so where do you get it from?

 

spence7: no, "Tek2" refers to a reprogramming of certain ECUs. "Tek3" is another reprogramming. Both use software developed by ECUtek. ECUtek software can reprogram certain models of ECU, typically UK MY99 onwards (their website probably specifies what can be mapped and what can't).

I'm not entirely sure about the "Tek1" job, it's not discussed often here. Tek2 is an off-the-shelf remap for cars with standard modifications (like exhaust and induction). Tek3 is a custom map for your car alone, it takes a base map and then is optimised according to how your car is specced and behaves. Tek3 remaps take longer (about 2 mins for a Tek2!) and cost more wedge, but you get better results.

 

Mickey, I usually use Pro-Boost from Revolution.
At the minute I use Millers and waiting for Andy at Tsunami Racing to sort me out with a couple of bottles of NF.

 

I think its a little bit excessive to get a remap for optimax fuel i have a 95 wrx jappy import just been for a week long ragging the **** of the car in Austria, Switzerland, Italy, France with subaru club Netherlands 45 alpine passes up to +/- 5000 ft even had to run the thing on 95 ron italy as no super only 95 fuel,over 2500 miles oil temps were hitting 130C no probs with any of the cars if something was gonna give cause of fuel it would of done then under these extreme driving conditions

 

Run your car on Shell Optimax.Re-set the ECU. If you get no pinking/knock on normal driving that is fine. If you are going to drive very hard then add 1ml/litre NF or a bottle of Millars Pro Boost. If you get knock with normal driving and Optimax then you need to run an Octane booster all the time.

 

Should have added that what Tony says is spot on. Paul or David can make changes to your ECU but that costs money and from your post I recon that is not what you want to do.

 

ok cheers fellas, so ritchie how much does a bottle of millers from revolution cost and how long does it last coz Tsunami charge i think £15 per bottle of NF, was gonna get some NF tomorrow coz hoping to get my WRX within the next weeks or few days!

 

Don't know anywhere in Newcastle but if you are ever down South (ish) drop Pavlo (off the bbs) an E-mail...... the guy is a star, he did mine for me and the car ran like a dream

 

Revolution only do Pro-boost.
NF works out cheaper per fill eg 1ml per 1 litre.
Pro-boost comes in 1 litre cans and recommends about 1.5-3% per litre so a 50 litre tank will need about a can full to meet recommendations. Some people just use a third of a can per fill however.
Tsunami stock Millers Octane Plus which is 1 bottle per fill and are trying to stock up on NF but it goes very quickly, Andy said he would try to keep a bottles for me though

 

well i might be at tsunami tomorrow do you think they will have any left?

 

Bloody hope so, been trying for weeks to get some!

 

Why do you want to remap for Optimax?

Just to clarify my question a bit further - What RON do you believe your 95 WRX is mapped for?

Chris

 

100 - 102 ron

 

correct - 95 WRX is mapped for 100 - 102RON ! Remap for optimax would allow all driving conditions to be in theory fully safe without need for OB

I have a 95WRX and add 50mls NF per tank - purely cos it sounds so much smoother and nicer mid-top end rev range using it. Going back to optimax alone it sounded rougher straight away. OK it needs time to adjust but it does sound smoother and better top end with OB. More power and economy as well I believe ! Just hope the knock reduction isn't a lie.

 

Sory guys - I asked the question as I believe this is just one of those myths - Old wives tales.

UK PPP is based on Wrx 95 ECU - the fuel & ignition maps are practically identical - Prodrive recommends 97 RON.

I believe the Jap maps are *actually* tuned for 98 RON.

So Optimax should be fine without Octane booster (Unless of cause you've raised the boost etc.)

Chris

 

yeah me too must invest in a knocklink asap, how much are they from BR developments and how much would a garage charge for fitting one?

cheers dears!

 

Try a couple of auto-electrical shops from yellow pages or even auto electrics/ installation of I.C.E. however it is very easy to fit. Microphone can be bolted on to existing set screw above no.3 cylinder for instance. Cable back into cab, suitable location and power feed and Bob's your uncle.

 

Chris, are you serious about that ? If so this is a revelation... it's been a myth for a long time that all the imports are tuned for 100ron and using 98 is just the best you can do in the UK without OB.

It does tally though in a way, I read a post once which claimed that knocking was substantially reduced / almost completely removed when 98RON fuel was used versus 97RON. I think this was a 95WRX as well.

However, I do notice a quieter and smoother engine when I use NF booster....maybe this is not actually increasing the octane though just improving the flame front / combustion efficiency. I only 50mls per tank so I guess this shouldn't equate to a large increase in octane rating.

So bottom line is optimax can be used completey safely...even for track situations if it's mapped for 98 ?

Cheers
Alex

 

is it improtant when fuelling up that you put in the octane booster first?

 

If you're running standard boost then Optimax should be fine.

There's no harm in putting booster in but I don't think its necessary.

If you're concerned then monitor the AFR & Det for further reassurance.

Chris

 

JDM is 100RON. Optimax is 98.3 RON. Running a car, mapped for 100 on 98.3 will likely result in det and even if not severe will result in premature failure in time. Hence the need for NF or similar.
This applies to Japanese domestic market cars (Jap imports) mapped for 100 RON and not UK or European Subarus.

 

now thats an answer

 

We'll agree to disagree then Harvey.
