Restoring a 1999 impreza turbo 2000 uk car,decided to give it some more power,exhaust panel filter decat.But now looking to purchase a ecu upgrade.There are two available to me,they are both prodrive.My question is would both fit straight plug and play,or do i need to get them coded to my vehicle(what does this mean),the ecu details are as follows



on cover the following information SP sti 1001056110 A18-000DIX 0418 3 PLUG ECU



Next ecu the one i think thats most favourable



on cover the following information J2 2261af041 A18-000-do2 This ecu states by the seller just plugs in



this coding question is what confuses me???



Any valid advice welcome!!!

SP is the correct prodrive ecu for 99/00 cars & is just plug & play, to need to code any keys etc.

to get the best out of it you really need the upgraded Y-pipe, either the prodrive one, or an STI item,

Tidgy

its just a map change, not an upgrade. get existing ecu remapepd and job done.

thanks gambit and tidgey,gambit so no coding problems with sp,just plug and play for uk turbo 2000 year 99? also any links to y pipe informationwould be helpful for example ebay uk sale Thanks

prodrive Y pipe looks like this

Std Y pipe looks like this

Prodrive one just flows better - you can pick up the Y pipe usually for about £40

Ecutek remap is £550+vat for reference! but i wouldnt be going down this route unless changing the turbo

270bhp is achievable on the Prodrive ECU & yes its, to the word, plug and play

just to add, i had an MY99 uk classic for 4 years, 3 of which was running the prodrive ECU, and this was in Belfast, running on 97RON fuel. never skipped a beat

the fella who bought the car off me is still running it in same spec and its on 120k mile now

bang for buck you wont beat the prodrive ecu, and being in NI you have no ecutek mappers except those that come over for 2days every 6mths.

Thanks alot Gambit i appreciate your straight talking and information going to go for the sp sti ecu,put it in my subaru impreza turbo 2000 awd,hopefully give it better power and driver appeal,my folks from east belfast,i live co down myself thanks again Genie

The gain of a PPP ECU is barely noticeable on a MY99 which already has a slightly better map than MY00. I did blinded tests with a boost increase with MY99 vs PPP back in the day. If it is cheap it would save you doing ghetto methods of raising the boost limit.

cheers John appreciated

Tidgy

270 on a ppp ecu? you having a larf?

geniershow

tidgy,I agree with gambit,the sti prodrive sp ecu you could achieve in the 'region' of 270bhp,with full de cat air filter,440 injectors and td04,even with sport cat.Did my homwork with a tuner.

john banks

PPP, decat downpipe and boost controller did 257 on Maha, where a MY00 with full exhaust did 220. There can easily be more differences between dynos than standard vs modified.

Tidgy

we talking off the shelf map or after custom remap?

sssssteeeee

ecutec map or depending on plans alcatek the new boards have much to offer at a good price to.

no.

PPP ECU, prodrive Y-Pipe & center resonator removed
HKS Panel filter
Newage Intercooler
Std Catted Downpipe

only other thing was acuator arm tightened up. held 1.2 bar (as opposed to 1.1bar std on PPP, reading via PSI3 Datamonitor)

257bhp/268lbft

Sport Cat Downpipe was then added, but never dyno'd so id say yes 270bhp was possible -unless JGM's 'road' dynoplots are optimistic

you can crank the boost on a std MY99 ECU as they run stupidly rich as John banks says, only difference would be the midrange improvement the PPP gives which made the car far more driveable imo

So can the prodrive ecu be remapped?

Bob Rawle

Yes it can

That delta dash plot figure is reading the peak, in practice you should take the average of the high and low points across the graph but its not a million miles off as the graph is decently smooth

270 is possible with a remap and supporting mods using 97 ron

cheers

Who maps the Prodrive ecu?

Shane

iTrader: (6)

Don't remap the Prodrive ECU, get the standard ECU remapped and sell the Prodrive on, a remapped standard ECU will give exactly the same results as remapping the Prodrive one.
I run a Prodrive ECU, Green Cotton Filter, Decat downpipe, Prodrive Intercooler Pipework and prodrive back box and have left the centre cat in place to stop the turbo over boosting, it made 251bhp on Surrey Rolling Road with fuelling spot on.

Nice, you can't remap standard ecu on 1997-1998 without esl, and sure the same for Prodrive ecu same year.

What year is yours?

Shane

Mines a 99, both the original and the Prodrive/STi ECU for the 99/00 cars are only mappable by ECUTEK or ECU LABS. Only other options are finding a compatible aftermarket ECU like an Apexi Power FC.

Out of interest, did ESL ever work on a solution for the "phase 2" MY99/00 cars? I can't remember if they did or not (but that the venture just petered out - so to speak?).

Hi mate I'm running a prodrive ecu on my 99 Impreza. From what you have just said I may have removed the wrong cat.

My understanding was you take the centre cat out and leave the down pipe one in place but you have done the opposite.

Can someone confirm which cat should be removed please

Shane

iTrader: (6)

PPP spec was to remove centre cat but they had to meet emissions controls, I didn't If you go full decat on the standard or PPP 99/00 ECU you'll have overboost problems, by leaving the centre cat in place it helps keep everything under control, a decat downpipe is a lot less restrictive than the standard downpipe and will help it spool up a biy quicker.
You've not done anything wrong by removing doing it the way you have, it's just that there are better gains to be had by keeping the centre cat and changing the downpipe.

SunilWRX

Thanks for clearing that up mate.
