Hi all,

I am still trying to get hold of one of the original Prodrive PPP remapped ECU's for my MY94 scoob. But I was wondering just what potentially could happen to the car after fitting it. Basically, by taking the car up another 35+ bhp surely must put more strain on some of the main components, most likely shortening their lifespan...

... so what can I expect to happen?

Regards

if its an official prodrive ecu, then it shouldnt put any huge strain on the engine, and will be less risky than some other chips, however if your engine has more than 60,000 miles on it or you have excess piston slap then be careful! the engines arent bullit proof as many people think they are and and a new short engine is around £1200 plus vat and fitting! if you think your engine is in good condition, then go for it, just let it warm up for a good 10 mins before going on boost and let it idle before shutting it off. Also make sure you do regular oil changes!

 

The Pre96 Prodrive ECU upgrade was a replacement ECU badged 'Prodrive'. This had a 27C1028 chip in the spare slot on the ECU main board which ran an ever so slightly modified version of WRX95 Code (the Prodrive ECU for the UK wasn't released until 1995/6).

This was set up to give you 13.6psi peak as opposed to 11.47psi. But also gave a much better ignition and fuel mix for better torque at approx 3,000rpm.

I have one of these fitted into my MY94 Prodrive Edition (which came with everything except the ECU upgrade, origionally), or rather did have until we cracked the ECU Adaptor option. The Adaptor I now have fitted runs modified the code to give me 15.5psi. The Prodrive chip now sits in a small box in the garage ready for refitting when I sell the car.

The standard Prodrive 13.6psi map gave me 255BHP at Tuning Japanese a few months back, with TSL Backbox, ITG filter and Magnex Center.

See http://www.scoobynet.co.uk/bbs/threa...=119754&Page=1 or mail me for details of your options

 

Thanks guys for some good advice/explanations. I'd like to source the original PPP IC as my car is just short of 30,000 miles. If I do get one, and it goes well I'll no doubt be taking it to the next step with a more gnarly remap so I'll drop you a line.

Again thanks, and all the best for the holidays,

Two beers,
are you still looking for a PPP ECU? May be able to help you with that...

 

Is there a ecu upgrade for the 96 mcrea model, and what are the specs and cost for such a device ?
Can i also use it in combo with a diff chip (chiptorque) ?

See www.scoobyecu.co.uk

Or mail me

Or see my add in Scoobyshop (when I get round to re-posting the advert). I use one in my own car that runs 15.5psi. I expect that your Mcrae runs the same as my standard UK MY94 Prodrive Edition (11.5psi or 13.6psi if Prodrive ECU installed).

 

I SENT AN E-MAIL TO WWW.SCOOBYECU TO SEE IF THEY COULD SUPPLY ONE FOR MY 94 WRX WAGON , AND THEY SAID THE 94 MODEL HAS A DIFFERENT TURBO AND THEY WOULDN'T WANT TO FIT ONE TO IT AS THEY HAVEN'T GOT A MAP FOR THAT YEAR

 

What ECU are you running. If it's V7, 7D or Z9 then it's now not a problem.

mail me...

 

>If it's V7, 7D or Z9 then it's now not a problem.

Sorry to b*tt in, but what about 6D?
Anyone know what it is? and what to do with it?

I am still trying to source one, yes. I'm hoping that someone may be keeping one aside for me at the moment, but I'm open to other kind offers if you have one

Cheers

Let me know your email address and I'll mail you offline

 

webster... that was me that replied...

sorry if the reply was a bit short... im very busy these days...

Appollogies to anyone waiting for an adaptor (no cheques cashed though)..

Im also needing to test some still

The td04 is different to the td05, and the duty cycle maps would be different... Im intending to dump a map from a wrx wagon, then Ill have a look at sorting something..

David,

I have the map out of Markus's Wagon (Z9 ECU), if you want it. The Boost and Duty cycle maps tail of dramatically from mid to high revs.

The Standard Saloon Duty cycle causes overshoot and the inevitable fuel-cut.

I am waiting comment from Markus on the latest chips which he should of received over christmas.

 

Wouldnt mind a look.. Cheers..

You know where to email or upload

Hope you had a good christmas and new year...

David

 

>>If it's V7, 7D or Z9 then it's now not a problem.

>Sorry to b*tt in, but what about 6D?

You are not alone..i too have a 6D...unfortunately Scott and David don't have a map for it AFAIK so we can only wait to see if some1 in UK emerge with 6D ecu...

 

What boost does a 6D run as standard ?
If it holed about 11psi then it's likely to be the same/similar to a UK Wagon.
If it peaks at 11psi then drops to about 8psi then it is similar to a WRX Wagon.

I'm sure we can try something that hits around the 15.5psi mark.

 

2 Scott: according to gauge, originaly it peaks at 0,8 and holds at 0,7 in 1/2/3 gear...and holds 0,8 in fourth and slightly more in 5th (around 0,85-0,9b...depends on weather/fuel/whatever)...
Right now i'm running mine with Dawes Device at 0,9 in first 3 gears and 1,0 at 4th and 5th...i thing gauge under reads for cca 0,1b couse whan i was hiting slightly over 1,0b i got fuel-cut (which should be at 1,15b afaik)...hope this helps

Ola has a sedan and i have wagon...as i mailed Ola we both do have same ecu and similar mods but something is very strange about his car (imho), couse he can run 5th gear up to limiter at 280kmh...me, i can't pass 5,800rpm at 245kmh in mine...go figure

 

Sounds very similar to a UK map, which peaks at about 11psi.
Should be able to sort something out, maybe the 15.5psi map that I run in my UK Saloon.

I need to order some more PCB's, but David may have some stock if you would prefer he sorted you out.

 

2 Scott: Should be similar...i will try to crack open my ecu to see about that socket...is it there or not. Who will sort remap/adapter is up to you abd David...sounds good to me either way

 

I have a PPP ecu on JAP MY95, I get a fuel cut at 1.3 bar. The ecu was brought from a prodrive engineer not prodrive. The car seems to be running okay. Its been on the car for a year now.

It has made a vast improvement from the original. I don't know what mapping its running etc... but happy to find out if anyone volunteers.

 

Even more 2 Scott: If we have those empty sockets (bdolgu and me) and regarding that other thread about upgrading ecu where u mentioned to me that main problem is if we don't have that socket, if we actualy have one...is there a chance you can sort us out than?...

picture of EU 6d vers connectors (pinout is the same as in UK 96 ecu)->

 

One/Two weeks is not a problem...at a moment we have 50cm of snow here so it's not like you can explore added power that easy

As i saw in your advert you can provide one of 3 maps...i'm interested in either Stage2 or Stage2 Plus map...which one you reccomend?

Can you take allready done mods and tweak the map for them (in general kind of way)...It's nothing major but both of us have similar stuff...me, i do have Full decat and backbox changed...Blitz SUS air filter...So according to my AFR i'm a bit on lean side after that air filter mod...Anyway, whatever you think it's best please...
Paying...you can mail me so we can arrange it either with CC or money transfer (CC is easyer, i think)...but again, whatever u think it's best for you..

Thanks upfront...

BTW. one question though...is it possible to DIY remap EPROM afterwards ? I mean, u fill it with one map and send over mail different code...can i remap it?

 

Stage 2 UK map would be best suited for your application.
CC not possible as we are private individuals.

remapping is possible if you have the equipment to blow EPROMS and have suitable files/spreadsheets to modify the code.

 

Ok Scott...we will sort out paying trough money transfer or something...we can switch to mail now...

As for remaping...if you can provide info about what i need to have to reprogramm eprom i think i can find some1 who has it..

 

More 2 Scott: The 6D ecu have a empty socket in the ecu.
I think it's the same as my96 uk, only LHD? isn't the ecu connectors diffrent on RHD and LHD (upside down on one of them?)

As to why my car is as quick as it is for no apperent reason, I guess I'll know when it goes boooom and I have to open it up

Oh, by the way, it boost ~0.8bar standard and fuel-cut is just over 1bar on my meter

Sounds like it's not going to be a problem and as you say it sounds similar to a UK ECU/Map. I am in the process of ordering another batch of bare PCB from the supplier, and hopefully will have these in a week or 2. In the mean time I think you need to decide how you intend to get funds from Croatia to either myself of Davis in the U.K.

Boost on a standard UK is 11.47psi
Fuel cut on a standard UK is 14.87psi
Boost on a PPP UK is 13.64psi
Fuel cut on a PPP UK is 15.65psi

A PPP UK map is just a WRX95 MAP with the following changes :

7 out of 256 values changed on the fuel map (PPP a tiny bit leaner, but very minor difference).
4 out of 256 values changed on the Ignition Correction map.
14 out of 64 values changed on Target Boost map (PPP runs slightly more boost, 13.64psi as opposed to 12.7psi).
8 out of 64 values changed on Boost control map (PPP adjusted for above reason)
Speed limiter on PPP map increased to 170mph from 112mph.
