Hi peeps..

I will slowly be updating some parts on my wagon 96 and I know that after mods you need to get a remap.. My ecu in the car is a 3b a18000d19 6404..
Is this ecu chipable or mapable, also I read that some people get slightly better mpg after remap is this true...
cheers for any input.
What basic mods shoud I be starting with.
it is a my96 wagon 260..
All it has is a Mongoose exhaust from cat back...
Other than that it is standard..


If this is in wrong section please move if needed.

yes the ecu is chipable and mappable with the use of a ESL daughter board.

It all depends on what you want to be your max power/torque.
In standard form your car will be 220ps unless its a sti 260ps.
You could buy a z4 ecu and a td05 turbo which will take the car to 260ps as the saloons are, or a td05 and chip your ecu with decat and better fuel pump should see around 280bhp.
If your going for more than that then you will need a bigger turbo ie td05 or vf bigger injectors and a mappable ecu ie simtek.

Decide what power you want or max budget and take it from there.

According to the code on my car it is 260 already and would like to see 300

Must be a sti then and they already have a td05.

Keithslippery

GF8C58D = .WRX STi V2 5 door / 258 this is my model it is a may 96 import, so looking to gain around 40 - 50 bhp to get to around 300 bhp. And it has a td04 on it..

if its a sti then it shouldn't have the 3b ecu, that ecu is out of a wagon wrx with the tdo4 fitted.

BLACK V5

Thats also the code for a wrx wagon. Does it have the sti seats and strut brace and silver intercooler?

GF8C58D is a wrx code as well.
if you have a 3b ecu and td04 then you have a wrx.
do you have blue seats par chance?

Keithslippery

Yes the seats are blue all over not twin colour.
It is a wagon so being its may 96 and with the model code supplied it is a 260 model as the 220 model is for earlier date..

No to the silver intercooler and no to the strut brace...

So its a 220ps wrx then.

Keithslippery

Yes I have that now thanks so need 80 - 90 bhp gain now then lol, what sort of mods am I looking at to get to this figure without major costs if its possible..

Fuel pump, fuel regulator possibly bigger injectors better turbo and better intercooler.
I presume you are on the prefacelift slanty cooler.
All this isnt cheap.

The other route is chip, decat, td05 and a fuel pump this should see you 280, some have got more. This is the route I went and cost me.
£51 for the turbo
£110 for a chipped z4
£50 for decat
£110 for magnex cat back
£70 for walbro 255 pump.

This makes a huge difference to the standard power.

Keithslippery

Yes i have the slanty intercooler, does the td05 fit on without any other mods and how did you get yours for £51 lol.. Already running magnex cat back can get decat for about the same so if I looked at turbo, fuel pump bigger injectors and decat then the remap we should be getting there...

Thanks for all the input though it is greatly appreciated...

Ebay was my friend, it had a stud snapped off in it, bit of heat and it came out.
If your going that far you may as well put a front mount on cheap as chips second hand and a big improvement over the slanty.
The turbo goes straight on but you need the td05 metal water pipes.
You may get away with the standard injectors I dont know for definit, but if you fitted bigger then with the other mods and a nice map you will be pushing 320 maybe 330.

The cheapest acceleration mod is to strip it out, if your after a fast b road blaster I would look at whitelines products to stiffen it up a bit, also I aim you have the standard 2 pot callipers on which being are sh1te.
Somehow I managed to get a set of 4 pots with drilled and grooved disks for £25 which are a big improvement.

These mods can give you the equivelent to 30bhp.

Keithslippery

That would be nice lol but clutch and gearbox probabl die then..
As you can see im new to subarus so learning as I go along..

dj219957

burbling1, how did the chiped z4 cope with the decat? did it overboost/spike?
ive got decat in the garage but dont want to fit it to my scoobyecu chipped ecu for fear the car might overboost/spike and det its brains out. going to save for a boost gauge and maybee a knocklink first.

andy306

i went down the route of tdo5, front mount, airfilter, back box and z4 chipped i saw 309.9bhp and weighing 1214kg as i stripped it saw me doing 12.74 quarter mile at pod terminal 110mph but that was only with std injectors and that is a 220 wagon ie 2000turbo

ive now got a fully rebiult closed deck block with some nice internals and yellow 440c tubular manifold 3" exhaust fully decated straight through and some other nice shiney bits lol still running in though so dont know its potential yet should see a possible 350 due to limitations of turbo and injectors they will be updated in time though

there is probably hundreds of people who run a ecu chip from one source or another that have a decat and have no problems at all, me being one of them, the best thing to do is as you said get/borrow a boost gauge, fit you downpipe and take it to a reputable rolling road specialist such as power-station and have the fuelling properly check on the dyno under load, relying on a "knocklink" or another device and trying decide weather or not it is actually detting or not is IMO a waste of time and good money, you will know pretty dam quick if you over boost as you will hit fuel cut and if you have ever experienced this you will know how it feels.

Keithslippery

You mean ecu like this one then and then get it remapped

there is little point in spending out on the z4 ecu as it makes no difference when mapped as it reads off of the chip/daughter board.

Keithslippery

but would that one not be a better start as its 280 supposedly where mine is 220

my94wrx

iTrader: (4)

better start for what chipping? or a better start to run your car around on? if its either of those forget it as for the former i explained earlier that it doesn't matter what ecu is chipped as the end result will always be the same, if its the later forget it you wont see and gains as the z4 ecu is specific for a tdo5 turbo not a tdo4, the fuelling boost and timing will be all over the place and could run lean where the tdo4 needs fuel etc etc

How much money have you got, seriously!

Your car could well have been cheap to buy initially, but to get to where you want to be will cost the price of a used newage ontop. Decide now, do I really want to spend the equivalent money of a better more reliable car on a car worth at best half of what I need to spend ?

My answer was yes

Keithslippery

I was asking this because I now have a td05 that can at some stage be put on and I thought that I would be able to run that off of the z4 ecu stated earlier....as im new to imprezas I am just asking questions after reading many threads if I didnt ask the questions I wouldnt know. If I knew the answers to the questions then I wouldnt ask..I hope that someday I will be able to help someone with a question if I was able to..
I know the z4 is specific to the td05 hence why I looked at getting a td05 with the aspect of fitting a z4 to it to run it.

Keithslippery

And my answer is yes I would like to spend the money on the classic one I have if I was looking for that power from a newage I would have bought one but I didnt I prefer the classics and I wanted a wagon, I also wanted a cheaper one so I could play with it, and learn from it..

I have a wagon STi ECU which is TD05 specific and will match your existing setup.

Fair enough most people are naive to the costs involved in modding early classics and think a DV, induction kit and chip are a license to rocket ship status Clearly this is not the case

Keithslippery

I know where your coming from but I am 40 now and all that was done 15 odd years ago. I didnt want to upgrade things based on the td04 knowing that it is better done on the td05 not interested in noisy dump valves or hoovering up the tarmac with the biggest induction kit going, I am happy in the knowing that I would like my car running at about 300bhpish, not needing any more than that, its not the best impreza in the world but it is mine and I will repair things on it slowly as things break due to wear and tear rather than because i've overdone it, now I have the td05 or should I say it is coming albeit secondhand and Iknow the existing ecu in my car wont run it so was looking at putting a z4 in it to run with the turbo. It will be getting k&n panel filter in the next week, my question is can I run the tdo5 with either a z4 or the ecu above without an extra remap, because I will be getting probably a fmic soon but not right now and I know it will need mapping then. Thanks for your help anyway..
