PPP ECU into a WRX bug
 

Hi,

OK, I know a true remap is the better option but I have no confidence in the local RR in Helsinki, between me and a friend we have been there 3 times and not once were we even slightly impressed with quality of work.. took them 4 hours on a mates C20XE with Jenvey 45's and Emerald M3D to say, well it wont rev above 6500 and I dont know what the issue is, might be cam timing slightly out.
The other semi-local RR when i asked, said they would need to sell me a ViPEC or Autronic ECU.... umm. no.

So, I thinking can I plug a PPP ECU into my WRX bug?
As to my knowledge the PPP was ECU, sports cat downpipe (STI only?), mid decat, blue IC pipe, air filter, fuel pump (STI only?), rear box. (have I missed anything?)

My car has KN air filter, PPP sports downpipe and HnS 2.5" down pipe back exhaust.

I know I might need a new Walbro 255 fuel pump.
1) can I just plug in the ECU to my WRX, re-teach the key and go?
2) will my Sigma (I think it was standard) alarm complicate the issue?
3) what other issues will I hit?

assuming the above questions dont give me any show-stoppers...
I think Im looking for a V3 (3V?) WRX prodrive ECU NOT a 3D (D3?) which was in the STI. is this correct?

your thoughts and feedback are appreciated.

You'll be easier writing the PPP Rom to your existing ecu.

Yup, the PPP isnt even that aggressive a map either from what I have seen. you might as well read up on doing it yourself via a tactrix cable, plenty of support on the romraiders forums too.

I think a lot of folk think that the prodrive map is a little special , but as you say it is quite a tame map , it obviously needs to be as it is a bit of a one size fits all affair
It's definitely a better option mapping from scratch and with time will yield far better results

HI,

the reason I was thinking a PPP map was becouse it is a one size fits all kind of solution.

By the time Im paid out for a tactrix £££££:eek: cable and a wideband sensor + gauge thats almost half way towards a full RR mapping session.
Add onto that the cost of my time... and its not a cheap solution.
Having 3 kids all under 5, free time is at a premium.

is there no alternative solution for the cable??... if there was Im tempted just to log whats happening at stock.... plug in a PPP map and see that its OK and leave it at that.

Vik

Hi mate there is a solution for the cable , a vag cable £6 ish you can log with a standard vag but not flash , but if you've got good eyesight or know Somone that can solder ,Small electronics you can mod it for flashing

Like this ( you must get the right vag cable if you want to mod it it's pot luck unless you've got a supplier that usually sells the type you need

I assume you mean just plug in a prodrive ecu and see what's happening ?
Not plug a map in
The cost can be as much as you want to spend with mapping , you can get set up for as little as £10 ,
I use my repositioned rescaled 02 for afrs ( been slagged of for it loads but IMO its fine ) but that's up to you if you want to go that way
The biggest thing with o/s DIY mapping is time ( and lots of it )
Like you say you're time is limited and valuable , so it may not be for you

Tony

The WRX PPP only needs a centre decat pipe and uprated air filter to bring the car more in line with the PPP spec. The fuel pump was not upgraded. Given you get the keys coded to it (don't forget to get all your keys done, then it should work. Yes its a bit diluted but better than stock, and probably as good as most DIY tuners can manage given limited equipment availability. At least you would know the car wouldn't blow up !
The alarm won't be a problem.

cheers

bob

BTW do not use a Walbro they tend to causes issues these days. But you should fit an uprated pump to compensate for you slightly different spec. HRC Performance HR255 would be a good option in your case.

cheers again

bob

Like loads of DIY tuners blow up then bob , ( what a stupid statement ) please give ( some DIY tuners a little credit
I've read blow ups are not just restricted To DIY either Bob?
The prodrive map IMHO is not worth bothering with for the gains it allows

I am using a Dynapex 260lph pump, had no problems with it and it is silent, had any reports on them?

Not aimed at you in any way toneh don't be so touchy .. thicker skin helps.

Don't denigrate advice given in support of a question asked.

The Prodrive map is a limited improvement, and Vik is fully aware of that.

So its his choice to do or not do ...

When you map as many cars as I do you see all sorts good, bad and very bad.

cheers

bob

Bob I'm not being touchy and I'm sure after some of the replies I've had on previous posts goes some way to prove my skin is plenty thick enough thanks

You've come into this thread and like all the other pro mappers try And bring down DIY mapping and rubbish it !
There are many DIY mappers that are quite capable and you know it
What gets me is this section was started as the result of a previous mapping thread and in part can help the small majority that wish to start to map or improve their existing knowledge and talking of ( I doubt DIY would get better results and blow ups does not help improve anything at all , it's just total scare mongering tactics by a pro mapper , yet again
I've asked Simon , Duncan , stu direct to give honest advice and Only stu is willing !( and respect to him for that )
Why oh why do we have to keep hearing , blow up , poor mapping , if you want to help why not offer proper advice ie , your experience of ignition vs boost or little hints and tips
DIY mapping is not gonna be done on a massive scale and has a very limited amount of participants , so why the negative attitude , it's help we need not criticism
As for bad mapping DIY or pro everyone does , and that includes yourself , but I don't go running round shouting you've done this or Duncan has done that ?
In fact quite the opposite , like I said to stu unbeknown to both Simon and Duncan I have flat out declined offers to map cars and pointed them to the guys that do it for a living
Most of the time pro mappers come into a thread is when touting for work or it looks like the chance of a job ,,, it's so obvious it's sickening

Very encouraging quote for the self mappers out there wanting to learn (I'm not). For a professional mapper to say something like that! Nice image :thumb:

I agree with a lot of what is said here.

My advice for anyone wanting tips from the current pros is to search on the 22b forums. (posts within the last 10 years)Simon, Andrew Carr and Duncan all posted regularly when they were first starting out.

I think Bob know his audience here....

Im not looking to spend time investigating how to map.. then how to make a good map.

My orignal Q was about plugging a PPP ECU into my car..
I didnt think about Keys re-programming etc...
so whilst it might be easier to reflash a '1 size fits all' PPP map into my ECU.. I would need to get hold of cables that I dont have the skills to make, or the wish to buy a cable for such a short use...

Bob.
I did drop you a mail a couple of months ago re Finland.. I guess it didnt arrive?

Cheers
Vik

You could ask around the local forums in Finland and see if anyone is local with a tactrix.

I regularly help people of all aspirations with problems and other things relating to their cars, I am certainly not out to rubbish DIY enthusiasts, I was one myself. So lets very very clear on that point !!

Where I think I can comment with relevance I will, forgive me if my humour is not to your taste.

You appear to be a bit sensitive to some of my comments, I commented on your use of the oem lambda sensor which seemed to annoy you. But it is fact and that view is supported by other tuners who have posted in here. They just haven't seen fit to be seen as the bad guys yet (lol)

You will find me adding positives as well as "be wary".

So, if people want to map their cars then thats great, they will hopefully be cautious.

No matter what software is used, and I reiterate I have all the Open source tools on my laptop, the rules are the same and a car can be damaged if they are not followed.

I have previously stated I do not generally use the OS software since I have noted too many variances compared to other tools, I have never rubbished it per say merely pointed out that I see these variances. There are some good results out there from it, and also bad, but thats the same for cars mapped using the alternatives as well. But for me the devil is in the detail and OS doesn't have the level of detail I want to work with. thats my choice.

Vik, no not seen anything from you in that respect, just searched my email archives using key words, send it/forward it again to rbr@brdevelopments.com.

cheers

bob

I know pro mappers time is valuable and do not expect valuable time and detailed info to every individual who requires help , it would be nice just to hear some honesty , like If you want to have a go at DIY o/s here's some do's and dont's and if you put the time in you can get good results ( which I must say you most definitely can )
Regarding the O2 issue , I did say in the thread I'm aware of the inaccuracies of the stock scaled / positioned O2 ,,
But at the end of the thread I had moved the 02 and rescaled it and asked if anyone got any experience of this , and no replies

Now if someone said I've tried repositioned /rescaled 02 and it was showing 10.2 but on a couple of after market w/b it was 11.2 , then I could see it in black and white
As opposed to just , it's not accurate
