Z4?




Mines???


also wat gaines am i luking at from both

Quick comparison to what you are running and the z4

Boost Targets & Fuel-Cut Limits
WRX/STi Saloon ECU's 2C, U8, W6, W9 - As above, 11.47psi held to redline. Fuel-cut 14.57psi
WRX (1995/96) ECU Z4 - 12.71psi, dropping to 11.78psi @ 6600rpm. Fuel-cut 15.65psi


The Mines ECU run at the limit of what's possible (and normally mapped for the better Japanese fuel)
IMO you would be better off seeing what PolarPerformance can do (basically they place in chip in the spare slot of your ecu to run the car)

midas303

Import 94 wrx standard ish on the rollers 260 bhp, as far as I'm aware only induction kit and exhaust.

Steve Simpson motorsport ecu no additional mods remapped 303bhp 265 ftlb

Since then about £3000 spent than remapped currently. 312bhp 295ftlb. Std internals and 1.4 bar.

Should have left it at 303 saved up for an RA, or type R.

i just wanna break the 300 mark or get to 300 bhp will the z4 not take me there the mines is already mapped for another car its second hand so if i plug it into mine will it harm the car if i run it for a while b4 i get it mapped to my car ??????

The Mines ecu are normally mapped for specific mods.
An unaltered z4 is 260ps (with improved fuelling and a boost controller) it wouldn't be impossible to hit 300bhp.

what did you spend £3k on?

20withascooby

i was thinking that 3grand and on and extra 9 hp musta been gutted.wud i be able to run the mines ecu on my car tho without damaging it ???

20withascooby

when u say improved fuelling do u mean a fuel pump?????how much am i looking for a decent fuel pump and a boost controller???

Or higher bhp

AFAIK the Mines ECU is a very aggressive map.

Walbro 255l/ph fuel pumps are about £90ish

Boost controller, all depends what sort you buy. GReddy one in my car is about £300 IIRC. Apexi AVCR's are highly rated and about £250ish I think.

myblackwrx

iTrader: (1)

Increased fuelling would be a fuel pump (walbro) looking at £80 and an uprated fuel pressure regulator (£200ish).
Boost controller a Dawes device is about £25 direct from here 3 Bar Racing---Home Page or you could go for more expensive electronic ones can be a scheap as £150 or a bit more expensive.

Have a look at - Flat4online.co.uk Subaru Impreza Mitsubishi Evolution EVO Walbro Fuel Pumps Injectors Intercoolers for examples of what you can buy (not neccessarily the cheapest prices though)

Although you could look at PolarPerformance for their live remapping chip for early ecus along with fuelling mods,better tmic (maybe) will see 300bhp for £1000 perhaps

I have mate that uses a mines ecu and hit 289bhp on the r/r and everything was fine.

iTrader: (29)

Friend of mine running the Mines ECU, made 340bhp/29?lb/ft. Similar spec to my car.

My mates car didn't have a boost controller or a fmic though.
Had a look at your car and it is rather impressive for standard management and i guess it's healthy running that?

You Will have aTD04 Turbo, you will not see 300 without an upgrade to a TD0516g,

myblackwrx

iTrader: (1)

standard turbo on a 94wrx saloon is a td05 16g

mickywrx

iTrader: (29)

Not sure how you mean healthy running? It goes well, but my little injectors max out about 5k rpm, I would never advise anyone to take my approach.

I'm probably very lucky it hasn't blown up. Alyn from AS Performance mentioned that he was surprised it hadn't as he's seen less modded cars blow up.

I've got a Power FC under the bed (literally), for when I get some bigger injectors and turbo.

Thats a good figure for your mates car

Ok I stand corrected, was it 95 they went to the td04?

'It goes well, but my little injectors max out about 5k rpm' holy ****

At least you don't advise anybody going your route though
still impressive though

MY97 was the change i think but it wasn't across the entire range as the turbos were different on the wagons and the saloons but according to Andy Fs website

'Ranging from the smallest very responsive Mitsubishi TD04 as fitted to MY 97 onwards UK and Euro cars including pre 96 UK wagons.
Next there is the range of IHI VF series turbos fitted to 97-00 WRX and all STI 97 onwards
Finally the Mitsubishi TD05 as fitted to most pre 97 UK, Euro and WRX saloons.'

Like I say, not advisable but it seems to work for me.

95 WRX should have a TD05

20withascooby

i have a 94 wrx import ???

myblackwrx

iTrader: (1)

94wrx has a td05 16g the td05 was fitted to the early range of wrxs if in doubt have a look on the front of the turbo at the bottom (it's a bitch to get to though) and it should have some id marks on it.



Marking say TD05H (piccy of a 94wrx)

mblackwrx can u comfirm that a z4 ecu will just plug straight into my car no probs for me b4 i buy it and i shud feel a little diff yea???/

myblackwrx

iTrader: (1)

Yep because i fitted one to my 93 wrx it holds the boost better along with better fuelling (with a decat, full stainless exhaust and IK).

if you look at post 2 i put the stats up ,although it doesn't look like it's much different the Z4 is a lot smoother.
Don't pay more then about £75 imo as any more you may as well chip you r ecu.

20withascooby

ive got a full stainless decat de silenced de baffled exhaus hks dwn and rear section and a h and s centre section dont look much diff but hope i can feel some sort of diff.its 50 pounds thats posted aswell

myblackwrx

iTrader: (1)

That's a fair price (imo) but once you get it you'll want more ( i know i do )

20withascooby

i no but atm im only 20 and ive gone from a 1.4 corsa to this and omg i love it atm the sound aswell and when it pops a flame out the bk and ppl look and see how young i look its great suprisingly tho i get more police attention in my corsa then i do in this duno y

Brakes (which are fecking terrible imo) would be worth looking at and some subtle suspension mods may also be worth looking at.

mac12

all uk models pre 97 have tdo5 saloon and wagon

if you get the chip from scott.t plus full decat (which you have already) and filter and a better intercooler you will be close to 300bhp. (alot bette than a z4 ecu)
everything will be maxed out though i.e injectors,intercooler (if still standard one)

if you want to go above300bhp then it gets alot more exspensive i.e live mapping front mount bigger injectores etc etc then you have to be careful with your gearbox.

if on a budget i would go the chip route, roughly £150/£180 of ebay if scott still sells them on there,then £40 air filter and different intercooler lots of optionson on them (although yours may still be ok) and around 280bhp/300bhp.
