I have sourced a PPP ECU for my MY98 UK Turbo and want to try and fit it myself.

From what i've heard it should just swap with my existing ECU and run without any problems

Can anyone give me any advice on fitting

Where is the ECU located exactly in a classic, is it an easy job to do, and how do i reset the ECU afterwards, is it just a case of disconnecting the battery.

Also do i need to take it to a dealer to have the immobiliser reset, if my car has an aftermarker Cobra Alarm

cheers

the ECU is situated under the passenger side carpet (where the soles of your feet rest!). Remove carpet and you will see a metal 'can/shield', remove this and the ECU sits in its own 'can/shield'. Not sure on my98, but on a my99 it's just a matter of swopping plugs over. If ECU has been unplugged for a while there will be no need to 'reset' the ECU. Cant help with your alarm tho'.

It is a "very" easy upgrade........!

The alarm shouldn't cause any problems.

 

The immobiliser will though

Needs the keys recoding IIRC.

Cheers for the advice guys, will give it a try and see what happens.

thanks

'97 AND '98 cars WILL need the immobiliser re set with the new ECU or you won't be able to start the car. IIRC you may well have the same problem if you remove and then replace the original ECU, so just trying it may not be a great idea.

On my '97 car I pulled the carpet back, removed the cover and basically did everything bar changing the plugs from the old to the new and then took it to a dealer, they swapped the plugs over and re set the immobiliser for about £20.

 

i got a Prodrive ECU for my 97 UK Turbo...

swapped them over, and alarm/immobiliser was fine, didnt need anything done.... just plug n play

 

Unless someone disabled the immob in the ecu ??????

 

I just phoned my local dealer and they quoted me £16 to redo the keys, but £65 to fit the ECU. Had a little argue with them and seems, i will have to fit it into the car on the road outside and then push it into their service garage!!!

makes me laugh!!!

 

If you have the carpet up you can swap the ECU in about a minute. Its just 2 plugs....

Pull up right outside service bay doors at dealers
Lift up the rug
Remove 3 nuts
Chuck tin pon in back
Remove ecu and plugs x3
Plug in prodrive ecu
Try and start ?
If it does tell the thieffin ****** in dealers to do one
If not they will have to program keys cuz your blockin the way
Pretty damn easy from where i'm sittin LOL

 

I like that, good plan, definately not paying for something i can do myself so will change it there and just get them to do the keys!

What sort of change in performance should i expect, I've heard extra 20bhp or so over standard in the MY98

 

I think 20 might be pushing it. Depends on your mods. Will be better than the one you have though

The PPP came with a larger I/C hose, larger back box and and uprated panel filter from memory?

I already have an STi intercooler, an HKS Hypermuffler and full decat so hoping it will improve the torque more than anything??

 

Just being a bit diplomatic towards the robbin ******* at dealers lol
I think the figure prodrive quote is 20% Torque
The 97\98 prodrive ecu was pretty tame and as you should know you carnt do anything with the oem one..
Save ya pennies and get apexi well worth it.
Heres a link to the ppp my 99 gives you an idea.

my immobilizer works? wont work unless i disarm it on alarm.... i have a clifford alarm... if i dont start ignition after 30seconds it reactivates...

good enough for me

 

Could you tell me how to tell between a Prodrive ECU and a standard one ? is the label different ? whats is look like (Maybe a pic if poss) ? Cheers

 

it will have a pink sticker on it with Sti on it or something, cant remember from memory.... it left the bubble wrap and got bolted down 10seconds later lol.

Thanx for that guys I`ll get her in the garage and have look now.

 

Some do some don't.

Fitted PPP to a 1999 expecting to get keys recoded, it was fine. The car hadn't had a battery in for 2 months or an engine either. Started fine on OE ECU then turned off, disconnected the battery replaced ECU. Fine.

Did another 1999. Immobiliser needed doing. Why?! God knows.....!

Would I be able to fit equal length headers wit a prodrive ecu on a 98

 

Hey guys, im new to scoobys.
Can i put a STi ppp ecu from an 2003 straight into my 2002 WRX without doing anything else?
(already fitted COBB mid section and back box, plus a mesh panel filter)
Cheers,
Mike

 

You cannot put STi ECU on WRX,i'm afraid.
Because your WRX lacking AVCS and other features and this will cause more problems than one...
Probably wise for you will be get your ECU mapped etc.,its worth to do
