If you're upping the boost much on a MY02 (eg by fitting the ecutek), I'd recommend changing the up-pipe first/at the same time. Higher boost can apparently cause the up-pipe cat to break into pieces and get into the turbo - somewhat undesirable! Decatting the up-pipe also brings the turbo in earlier. Also recommend fitting a samco intercooler hose as the standard one has been known to split under higher boost and is a bit restrictive too.

Potential power wise? My MY02 with decat up-pipe, sports cat APS system, ported headers, samco interccooler hose, and an Ecutek gave over 280bhp from 5800-6800 (284bhp peak) and over 260lbft from 2800 to 5300 (272lbft peak) at Power Engineering on the day it was mapped. Is now good fun!

Cheers for the info guys. Now wheres the best place to get it from??

I have a scoobysport uppipe for sale - drop me an email.

Also...

This log was done very soon after the map upload. The power outputs improve over the following 100+ miles and up to 20bhp can be added during this phase of self learning

Pete,

I am dumbfounded !!! This is a regular MY2001 UK WRX ?

Do you have a chart for a STI-7 ? My JDM STi-7, fully decatted ScoobySport turbo back only got the below result:

Does my car look like it is running ok or do the remapps really make that much difference. Again, I am Shocked !! the UK WRX blows the socks off my JDM STi 7 ?? Unreal

Cheers,
Ray

Razor2001

Just for comparison the above car you remapped is doing over 210 ft. lbs at 3,000 rpms, my JDM STi-7 is only doing 130 ft. lbs at this point ????

Pete,
Can you get a graph like that for my Sti7 you did a while ago or does it need to be plugged in again?

Ray,

Remapped WRXes with full systems are very potent on the road, and will eat a standard JDM STi for breakfast If one has a "play" with the STi it comes alive and makes much more than a WRX could possibly hope to with the stock turbo and injectors... change those and the WRX becomes a different animal altogether; we've got one that's making about 275 BHP at the wheels with 1.25 bar boost, and it's getting pretty close to maxing out the STi injectors we fitted. I could lean it out a bit (still running it damn rich!) and raise the boost a little to get the magic 300 BHP at the wheels but I'de prefer to play it safe, remember this puppy is still running a standard TMIC which is massively smaller than the STi!

Torque comes in really low down on the WRX with it's diminutive TD04L turbo, which is why they're such a joy to drive day to day, especially after they've been remapped. Having said that I can get the boost in strong by 2700 RPM on a STi VII Type UK, but that is with the smaller VF35 turbo, so ultimate power won't be up to the JDM's potential. An STi needs more driver involvement and stirring of the 'box to get the best out of it, but keep it on the boil and it doesn't half shift

Your figures seem about right for a "stock" STi VII, assuming a 23% transmission loss you'de be making about 297 BHP which is probably about right (Pete, multiply by 1.30 for a 23% transmission loss, not 1.23).

Dave,

We'de need to plug the laptop back in; it's a newish feature in DeltaDash that was introduced after your car was mapped, but you should have a graph from PE, when you did that run that made 335 BHP (about 257 at the wheels?). I would be happy to Road Dyno your car, if you would like... perhaps at the same time you get the fuel pump fitted ?

Cheers,

Pat.

mccltd

Pat,

Will be up to see you soon for the Pump, and if you have any new tricks up your sleeve for more power let me know .
Ps.. the light has stayed off for ages now, great fix you have done.

Da\/e.

I like . Would love to see what a little ecu remapping can do

Cheers,

Razor2001

Would love to see a 100% stock JDM STI7 4th gear run to see how I compare. Oh, by the way my above run was at roughly 27 degrees C for whatever that is worth

Cheers,
Ray

Edcase

Pete - seriously impressive figures there. So let me get this straight this is an 01 WRX with a full decat system and a remap???

Presumably the next step after that is larger injectors, uprated fuel pump and some better cooling?

I'll be in just as soon as finances allow!!!

BL

Edcase

You have mail

Edcase

Hmmm...not as yet I don't?

Pete Croney

Ed

Exactly that, on our own full system including an up pipe. The real figure for me is that at about 2200 rpm, its got as much torque as the standard car has at its maximum, so you can imagine how driveable the car is

Edcase

I can confirm it goes very well, ferociously actually.

Forester_GP

Pete, is it possible to disclose what boost you're holding at the top as i'm planning a similar remap.

Thanks, George

BL

Lofi

Did you go for the Ecutek with a full decat??

chiark

I think I have just found the route that I'll be taking when I get my MY03

BL

Chiark

I have heard that the new PPP for 03's is going to be ecutek based as well. Maybe worth getting it that way (although more expensive) thus keeping warranty intact.

chiark

It'll be coming from Holland anyhow, so I'm not too bothered about warranty. I say that now, but if it goes *bang* then I might be a bit upset . But there's still confusion over PPP on EU imports relating to warranty, so I'll probably risk it.

The PPP will be ECUTEK but I am personally doubtful that they'll give it the same sort of power/torque as mentioned above. After all, they don't really want to be treading on the toes of an unmodified STI, do they? Or do they?

EVO this month reckoned 260-odd BHP, which is coincidentally just below the STI's standard output of 265...

Cheers,
Nick.

BL

Chiark

Mines an Eu import as well & ive given up with them & PPP. So ecutek it is.

When you getting your new car??

chiark

About 5 months after I order it . Probably July/August...

BL

Chiark

Have a word with Hans @ garage troch Think URL is

Tell him Bobby sent you.

I'm curious how the ecutek chip/firmware actually adjusts itself over the first 100 or so miles. Does it stop learning after a preset period of time ?

If not, why can't you make other mods (to exhaust, for example) and expect the ECU to cope ?

Pete Croney

Stan

It doesn't stop learning but by the time you have covered this distance, it has optimised its correction tables and will providing optimum performance.

BL

I have a MY02 WRX which i am planning on upping the performance due to a poor show on a rolling road well thats my excuse

Right, i currently have a HKP Hiper with a decat centre (both pipes), ITG panel filter + Forge VTA DV.

What sort of performance would i achieve with an ecutek map applied to this vehicle??

What would the differences be if i decide to install a decat downpipe along with the ecutek.

Another optionis to install an elcetronic boost controller. What difference would this moake over standard & compared to the ecutek.

Hope someone can help


[Edited by BL - 2/7/2003 3:55:02 PM]

elgordano

I'd agree with those figures. I managed 282bhp with full decat, ITG panel filter and EcuTek remap from an MY01.

These are Delta Dash logs of one we did yesterday. It had a full Scoobysport decat including up pipe.

Remember the figures are "at the wheels" not at the flywheel, as outputs are normally quoted. A very rough guide is to multiply by 1.23 for a flywheel figure.
