Right am thinking about modding the car a bit for more bhp. Here are the guidelines, do not want to void warrenty, and do not want to make anything to obvious for the insurance company. Therefore was thinking about an ecutek, anyone know how much they are, and where to get them in the south. Also if I do get one, will I have to have it remapped once I decide to get the exhaust and anything else, and is it going to cost the same or a lot. Any help would be appreciated.

when you say Ecutek, do you mean a PPP?
If not then a TEK3 Ecutek will surely void the warranty

 

Sounds good, the ecutek would void warrenty, but my local dealer is a friend and very lenent.

I find it strange that you can afford an STi8 and yet you are willing to risk a £25K car for a £700 mod If you did have an accident there is a chance that the Insurance Co may find out that the car has had a re-map. IMHO it's just not worth it for the extra you would have to pay. I'm sure more of the specialist Insurance Co's will now know about ECUTEK.

Get the PPP if you want more power, at least that will also add value to the car as well as not voiding the warranty.

 

With PPP you keep your warranty and have 300 hp max on a good day, i.e. cold. However,if you change any part of the exhaust system over that used on PPP, even the backbox, you will void your warranty. It seems harsh, but at least one person on SN, has had this happen when his STi7 engine blew up. Now the PPP system may be loud enough for you but for many it isn't.

The alternative is an after market sports cat exhaust system or catless system, e.g. Power Engineering, Miltek, Scoobysport, H&K, Blitz etc, plus an Ecutek remap done by a reputable tuner, e.g. Power Engineering, Scoobysport etc. This should give you a great sound, at least 310-350 hp and probably a safer map. Of course you will lose your warranty, but you would lose it anyway if you modify the exhaust in anyway.

I believe PPP on the STi8 uses an Ecutek remap partially developed for Prodrive by Power Enginnering. This is a standard map compared to a bespoke map as described above.

Cost wise there is not alot in it. My own experiences with PE leave me to the opinion that my modified STi7 has more power, e.g. at least 10 hp above that of a STi8 PPP on a rolling road, a higher quality exhaust system, and a safer map. For instance all PPPs are now fitted with an uprated fuel pump, but for 8 months they were not. PE were fitting uprated fuel pumps from the start with their own system. Another advantage of a bespoke remap is that if you carry out further modifications the map can be adjusted accordingly and you have the opportunity of further map upgrades as they are developed.

To summarise it really depends on how much you value your warranty compared to what performance increase and future mods you are planning. Insurance wise it doesn't make much difference. For me there was no increase in premium for my PE remp and exhaust, but then I am twice as old at you!

The new ppp has been revised, so im told, now 320bhp!

 

I don't think so

 

"Sounds good, the ecutek would void warrenty, but my local dealer is a friend and very lenent."

That won't help when Subaru now send an independant engineer around to ANY car that has an engine warrenty claim - and are imposing fines/threatening to withdraw franchises from dealers who defraud them as i assume you imply your friend will do....

Best to stick with the PPP m8 - its awesome!

It seems that every time someone posts about such a mod, people with PPPs pile in and say it your engine will blow. Not one car mapped by an authorised EcuTek installer has blown an engine. There is an approved list of installers at www.ecutek.co.uk/pricing.

All of us are protective of this 100% reputation and will not tune a car to the point of destruction, no matter how much you bang the table asking for even more.

It wouldn't surprise me if Prodrive do up the figures as their original maps were without an uprated fuel pump. With the uprated pump fitted, 340 is easily and safely achievable with a custom map, so 320 would be conservative and fine for a "one size fits all" map such as the PPP.

 

Cheers for the advice, have got some info back from xtreme scoobies, and they are saying about £800 for uprated fuel pump, and an ecutek which would hit abouve the 320bhp mark which sound fairly reasonable, anyone know if any of these companies do finance, as I am a bit worried about taking such a large sum out, especially with uni coming up, would much prefer to spread the payments, and let the student loan cover them. Cheers for all advice, and I hope to get some more soon.

Chris

 

You won't safely get over 300bhp without some exhaust work too. Speak to some of the approved companies listed in the link above. They will have done many similar cars and will have a good understanding what can safely be achieved.

PE are just up the road, BRD are near you in Richmond and we are further out at Basildon. Plenty to choose from.

I don't think any of the companies listed do finance, but all take credit cards.

 

LOL
I thought student loans were for books etc?

 

come on you have a nova really dont you

 

come on you have a nova really dont you


if its a real sti8 how much is the insurance

 

I'd like to clarify some of the points made

Lemmy
When recalibrating the ECU with all our performance packages, we take the opportunity to use some of the engine protection maps that are not used as std. These generally allow us to make sure the engine is going to operate safely both when it is cold as well as when it's too hot. This is done so that if the intake temperature or the water temperature are too high, boost is reduced. On the road with the air moving over the car this will always allow the engine to operate normally up to ambients of around 38 degrees which we don't see here very often! What has much more of an effect is the less than optimal conditions caused by heat soak, typically seen in v.slow traffic or when the car has been stationary for any length of time, even if the engine is off. As an example, at 25 degrees ambient, the intake temp was 44degrees after the car being parked for 2 hours! On the road this temperature drops very rapidly to 2 or 3 degrees above ambient but in the confined spaces of a rolling road it takes much longer. Hence the inaccuracies seen with cars tested on some rolling roads where the airflow is not sufficient to cool the car as it would on the road.

At no stage have any company remapped or been involved in the mapping of our cars although we do have a very close relationship with EcuTeK. In addition PE were not fitting fuel pumps before we did, we actually found the issue on our car, albeit on their dyno, very early in the development cycle of the performance package.
I think you will also find that EcuTeK do not map ECUs, they merely provide experienced tuners the software to map cars although they do provide example maps which some 'tuners' use as a basis for the products they sell.

The PPP for the STI uprates the engine to 300ps (around 295bhp) only, this has not changed and there are no plans to change it. Info from Subaru tech helpline.

FI I am going the scoobsport route for 340bhp. Have spoken to them and am confident my engine wont blow up!

 

Our performance package actually gives 305ps and we have had cars dyno'd at higher figures. As far as I'm aware, nodody has accurately dyno'd cars with similar mods at significantly higher power outputs and certainly not as high as 340bhp

Mike

 

Think I will agree with Mike on that, 340 bhp is big claim to make given the variability car to car that does exist. Which is why the PPP is "stated" at 305ps I guess. Its possible that a "good" car would make close to that figure with exhaust/induction change and a detailed remap but to claim that as a consistent achievement is a bit "brave" imho.

The difference tank to tank of fuel is easily able to cause the ecu to pull timing and effectively lose such a car 45 bhp at the drop of a hat.


cheers

bob

 

I agree with Bob.

My mates STI8PPP on one tank of plain optimax achieved 230lbft/230bhp at wheels on DDRD with an IAM of 9 (intake temp 20 degrees), then the next day (on same road etc) with a fresh tank of optimax plus 1ml/litre NF and after an ecu reset achieved 260lbft/255bhp at wheels with IAM of 16 (intake temp 19 degrees)! Boy was he pleased, as that should put him over 300bhp at the flywheel

Octane rules

Just to add:

My UK STi8 with full Milltek exhaust, stainless equal length headers, uprated fuel pump and custom EcuTek remap - at PowerStation last week, on a very warm afternoon - gave:

300 BHP / 275 lbft

...admitedly this would probably be 340-350 on some other dynos in cold / damp weather, but it shows what is / isn't possible with the EcuTek'd STi8 - even with serious exhaust work (and not insignificant cost!)

Shades

 

My STi7PPP on Optimax and no other Mods(bar blue indicators) Prior to Fuel pump Fitting I got a respectible 287Bhp 250 Lbs-ft. Max Torque @61mph 4570rpm @ Powerstation,

So quite chuffed really and Warranty but you pays your money and you make your choice

15k miles has seemed to knocked the Cobwebs out of her and it certainly seems to go comparitively well to most other MY02STi7PPP's and MY03StiPPP's

While all the surrey lot are here I might as well reply, too.

Try Power Engineering in Uxbridge for Ecutek.
