Had my scoob 2 years now and love it to bits, despite costing me a bloody fortune to run :D I've noticed a lot of talk on the board of ecu's and re-maps and thought I'd find out what is available for my beastie. I'm not bothered about massive power gains, just want reliability, a bit smoother and not have to be so worried about finding high octane fuel all the time.

Can't justify spending over a grand on big name ecu's just wanted to know what other people have gone for with their earlier cars, ecu wise

Any suggestions? :)

Try talking to Power Engineering, I'm sure I heard mention of later software fitted for arround £600ish... I think.

Cheers, Roy. :D

Had the PE chip fitted on mine, uses a 2000 spec ecu which is remapped, and also mappable for the future.

Power increased from stock 240 to 265 (also got Blitz exhaust and induction), but much smoother and clean power delivery.

They quoted me 450 on an exchange business, but by the time you've had rolling rod set up etc your looking at about 600-650.

Let me know if ur interested and i will email you a copy of the dyno print out

CharlieH Drop me a mail and I can sort you a remapped ecu board for your car.. see diy ecu remap thread in drivetrain.

David

Charlie,

Been running a PossumLink ECU for the last couple of years,
currently running revision Q software.
As remappable as your likely to need, also a good monitoring tool (with optional hand controller). New they come in at about £1400 for the full setup (slightly out of your £ limit) but these can be picked up second hand occasionally on the board at reasonable prices. The revision Q software allows monitoring / data logging and programming via a pc (with the optional serial link)
Quite easy to get 300BHP + with one of these and the right mapper.

(Mine may be up for sale soon due to major "upgrades" on the car)

Pete

Cheers guys. Dave, interested in what you have to offer as I live in Harrogate so your not a million miles away. Will drop you an e-mail Sat about it :)

Very Quick of the mark there David.....keep it up ! I have a tried and tested 16.5psi map if you need it. Infact I'll upload it to our hosting site (Even_Pro1.sre, ODD_Pro1.sre).

I like what I'm hearing guys. Nice to see so much work being done on the board :)

I'm running an Apex'i Power FC on my '94 WRX. A very nice programmable unit with high resolution. But the lack of laptop software available in English kinda sucks, as data-logging is limite to 10 second graphs on the handheld display.

Mark

scott I have to be :D

Not many northerners you see.. :D

Ill give the 16.5psi one a try... dont know what paul set the ones I have at..

David

Mark -

Let me know what you think of the Power FC setup - currently importing one myself. Interested in any feedback you might have. :D

Paul.Houbart@TheGecko.biz

Hello David

I have a 93 WRX aswell would be very interested in re map and software etc

My email addy is kevmwrx@btopenworld.com

Cheers

Paul, the Apex'i unit is very nice, and easy to work with, and I love having the hand held controler to display knock, coolant temps, duty cycle, RPM, ignition timing, battery voltage, etc. It really teaches you a lot about how the car runs. I normally run it to display knock, RPM, injector duty cycle, and coolant temps, all graphically, so I can see the past 10 seconds. This is especially nice for knock readout and injector duty cyle, as you can see the events of the past 10 seconds.

Disadvantages include poor boost control set-up (I run an Apex'i AVC-R, so the PFC doesn't have anything to do w/boost control for me, anyway) and lack of available laptop software for true datalogging. Oh, and you can't view the knock readout and the map location that its reading at the same time, so for tuning, it makes things harder, you'll need a knocklink if you want to accurately tune out knock.

But it is a very powerful unit with 400 RPM resolution. The base map was way too aggressive, even running 99 RON. I had to pull a lot of timing under load. If you can get it professionally tuned, its a plus, unless you're comfortable doing this.

EMail me at alloutforjesus@hotmail.com if you have any questions.

Mark

Pete,

Get a Z4 ecu from a 95/96 WRX. This'll give you 260 out of the box.

Should cost 100 quid. No more...

Try Midland Impreza..

Sorry to jump on but I have a MY94 import so if I put on a 95/96 ECU then it should really be knocking out 260bhp instead of 240bhp.
Is the ECU exchange an easy job...i.e could a guy like me do it who is no mechanic or auto electrian :)
Also can an STi 95 or 96 ECU be put on as that has 275bhp ? or is the WRX engine/injectors whatever different.

Hey Guys,

Are the Jap Import STI standard ECUs compatible with UK Turbos from the same era? I have a MY96 UK Turbo and am looking for an aftermarket ECU with some oomph! Any suggestions?

The only one I have been offered so far is a Superchip conversion for £435.00 +vat fitted.This is from Falkland performance.

Not sure about the outputs of this spec.

cheers.

Uk to STI/WRX from that era is a no-no I think, but....

95/96 ECU into an earlier jap car is a piece of pi55. Under pass carpet/footplate. Just disconnect the battery to be safe and change the thing over, being careful with the block plugs.

95/96 WRX ECU is a Z4 (260ps on 100ron juice)
95/96 STI ECU is a 6k/7k(RA) (280 ps on 100 ron juice)

luvlee jublee
Daver

why pay £100 when we can change yours to be a z4 for £60 if you want... Uk to jap and jap to uk has worked ok for me... so assume sti works fine as well..

David

AFAIK - Superchips is a boost clamp.. and bleed valve... not good.

David I emailed you about your software option but I have had no response can you email me please with whats involved.
Cheers.

I replied this morning from my work email address... there is no software option at the moment.. this will change once my car is on the road and I can develop the software better..

David

didn't get that email mate probably hotmail playing up again !
YGM.

Bryan,

I emailed you back however it would appear that you have subscribed to MAPS, as they`re IP records appear to be incorrect
it is most unlikely you will ever receive the mail :( Perhaps you
could contact them & advise them they really need to get their act together?

Pete

I've run a Z4 ECU in my UK (although only ticking over and revved in a garage).
It ran and gave no error codes but I didn't take it for a spin as was just checking my adaptor installation in Bryans ECU was O.K

David... hoping you might be able to answer something for me.

As you probably already know i have a gubbed TD04 in a 94 WRX wagon which i'm hoping to replace with a TD05. As you also already know the Wagon is 20 bhp down on the saloon, probably due to the smaller turbo.

Would the map you use for a 94 WRX saloon run ok in the wagon with a TD05? or are there other internal differences between the wagon and the saloon?

cheers,

Marty.

oh,...forgot to mention.. the ECU in the car is a V7? with the spare socket.



[Edited by marty_t3 - 10/15/2002 2:19:19 PM]

would it be safe for the engine to run say a 96 spec sti ecu in a 93 WRX? i know stis are supposed to have stronger pistons among other things, is the stock wrx lump able to cope with this extra 40 bhp easily?

marty... I have a v7 scott has a v7 so they work... the map would work with a td05... (mine is a 5dr as well)

David

David... you may well find yourself with another customer in a week or so :D

cheers.

my main concern is the sti revs higher than the standard wrx, if i put a sti ecu in a wrx as well as the 40 bhp increase wouldnt it also whack the revs up by 1000 or so.... surely that could damage the engine as the wrx doesnt have the stronger pistons etc the wrx has

ANy help/ advice would be appreciated

Hi Pete,

Thanks for the reply but I'm lost, maps? whats that.

Scott,

The car is running well, too well I've just had to buy bigger brakes now to stop her!

Rgds, Bryan
