have just pm'd as you suggested. once you have the ecutek license your map can be tweaked for approx a couple of hundred quid depending on the mapper.

Mike @ prodrive was commenting on another matter the other day that if it a mod is worth doing and it didn't braek the law (emmissions in this case) then they would have done it as part of the ppp.

Dudes, for the money and the effect - the up-pipe needs to be changed for a slip-jointed decat version.

You might not gain many horses BUT the drivablity is increased big time, spool up reduced significantly, thus a better car to drive with power up earlier, wider powerband etc etc.

Yes I did it to mine and it made the car very diff to drive i.e. Much better.

Just my 2 penneth worth from my experience...

I don't want the hassle of having a car that won't pass it's MOT without swapping back in stuff. Fitting decat up and down-pipes are also quite expensive in comparision to just doing the centre and backbox sections. I think both up-pipe and downpipe together will probably give 15-20bhp max? As has been said earlier, the car will be very noisy and I think mine is noisy enough with the Afterburner Vortex on there to be honest. I've heard a couple of full decat cars in person and they can be literally deafeningly loud.

As far as the regulator is concerned, it's recommended because at low engine loads the uprated fuel pump can overload the OEM reg which results in a rich running car under the conditions in question. I don't think this is a major issue to be honest and I doubt I will bother changing the regulator on mine. Fuel pump again might not be necessary as PPP uses the standard one but have heard claims that it helps performance somehow and is a worthwhile saftey precaution. I'd rather spend the money for an uprated regulator on a boost guage.

RRH

You can usually get a fully de-catted car through its MOT by replacing the centre cat and making sure its nice an warm- sometimes it works, sometimes it doesn't.

Downpipe is fairly easy once you get the bloody nasty horrid heatshields off providing the studs don't shear off.

Preacha, my point was that there's no point doing the up-pipe if you still have a cat in the downpipe mate

sily question alert

what does a fuel pump do , and is it essential?

Ben WRX Bug-Eye

Pumps fuel. Yes - essential.

Roojai

but you could save quite a bit of dosh on the fuel pump. Bought mine for 70 quid including vat and fitted myself.

why is everyone not considering the ppp as an option.why do people think the prodrive kit is lees power than a tek3 car??. prodrive arent a small back street garage are they!!! lol.
from day to day driving conditions change, the weather, the loading in yor car,a combination of both.as i beleive ,prodrive have to make the car as quick as posible with making it reliable for everyday ,every condition driving!!.
where as your local mapper, no offence ment,are mapping your car on the day,for that certain days conditions!!

Ben WRX Bug-Eye

By uprating the fuel pump you reduce the chances of fuel starvation and hence engine damage. It's not essential in the sense you have to get it done with the remap, but I've heard it argued that a remap will put the OEM pump under strain. If this OEM pump is wearing out and not quite as good as it used to be it may not be able to meet the demands of the remap at some point in time. I have also heard that uprating the pump will improve engine response etc - not 100% convinced on this one though. I orignally wasn't going to bother uprating the fuel pump but now take the view it's worth it for the margin of safety and knowning that this isn't holding back performance in anyway. On STI's it is essential that the fuel pump is uprated I believe.

I think that the ECU is able to adjust the custom map to the conditions of the day as done when the car is running the standard map. EcuTek cars generally give more power because the map is custom to the bespoke mods the owner has added. All the PPP does is fit their partial decat exhaust and map to that. A EcuTek car may have a more powerful exhaust fitted and an air filter upgrade that will be optimized with the map. I would expect my car to produce more power than the same car PPP'd for these reasons - I have filter mods and a less restrictive exhaust fitted.

RRH

The PPP solution is great if you want to increase the performance whilst staying within your warranty, and there is no doubt that they are one of the best. If you go any further than the exact spec of the PPP then the map won't be optimised, where as a TEK3 is mapped to your car with your mods, not a 'one size fits all'.

The PPP is pretty much the end of the line; they don't have a solution if you want to fully decat, change your turbo, injectors, intercooler etc etc etc, and at circa £1600+ it ain't the most financially viable route.

Also bear in mind that later versions of the PPP use ecutek software anyway.

Got MY02 re-mapped at WRC, it's got a prodrive full system and a walbro 255lt fuel pump and makes 290/312 and pulls like a train well happy.The reason i went that way was because i wanted to keep the warranty but then they hiked up the price! by which time i'd found a brand new prodrive exhaust system at a good price, so i fitted that and went the ecutek route, plus, as already said, you can add other mods and get the ecu adjusted!

Had to have my uppipe changed as the cat started to disintegrate and was making a rattling noise, fitted a magnex decat pipe and it certainly has made a difference, complete b****rd of a job though (5-6 Hrs).

RRH

was it failing as a result of tuning though?

fallwood

I suspect so as the car is running at about 310bhp, has made a noticable difference up the range, not as flat near top end.

Ben WRX Bug-Eye

That's very impressive 290/312. What boost is the car running to achieve that? Is this with just exhaust, fuel pump and remap?

Thanks, um i'll try and find my graphs! Yes full exhaust from a PPP, sorry i've just looked at my post forgot to add MY02 Sti.

Sorry for the slight thread hijack but are the cats shown in this the only cats or is there another?

^ that doesn't show the up-pipe cat ^

Ok thanks.

up-pipe is on other side of turbo

Ben WRX Bug-Eye

Nice! Bet that does go like a rocket - significantly more than a PPP'd car.

Ben WRX Bug-Eye

Sherlock - or anybody else who's had their car remapped - did you notice any change to the exhaust note on full throttle after the remap?

Cheers

On max chat it seems a bit more "raspy" if thats a word? but on tick over and normal driving i didn't notice any change.

I was well impressed with it after i had it done, it really does fly now, I was suprised how much more it pulls and it just keeps going.
FMIC and cold air induction might be next, so i'm saving now

Ive got one of the original piggy back PPP's on an MY01 WRX.... can this be ECUtek'd????

I thought of doing the up-pipe and down-pipe route -but would also like it re-mapped at the same time?

Jza

not much except for all the pops and bangs on over run

BrynO

Yep, they just take the piggyback chip out then flash the ECU..

If you are going to do the up & down pipes at some time, worth doing these before getting the Ecutek done (or you will need a further session to fine tune the map after the de-cat mods)..
