what companies still make chips for w6 ecu? i have full decat system and only looking the car to be 270-280bhp

 

I ran a Mines ECU on my 1995 wrx, never missed a beat, and pulled like a train.

 

I was looking at them but they seem to need v power fuel,in my area best fuel I can get is 97,polar chip seems to be my best option but can't find any for sale

 

Yeah defo need a decent fuel, or octane booster.

 

A fellow county down man , nice !

Youre best bet will be an ESL daughterboard, can sort you out with a real top mapper too if you need

 

Cheers,think I've got sorted,been offered a z4 ECU or 7k,gonna lift the z4 tonight to see what difference it makes

 

z4 is out of an import. It wont like the 95/97 ron.

 

My car is a import ,been told 97 works ok with it,was told 7k would need 99/100

 

My '93 WRX (originally with a w6 ecu) is running a z4 - it's totally transformed it, to the point where I've scrapped any further power-extracting plans!

I've always run it on V-power, but then I did so before swapping from the w6.

 

Feels like 2003 in here

Z4 would be just about ok on an otherwise standard car on 97 and was from the 94/95 WRX with 260 PS.

Shouldn’t really run a decat on it though - if you’re going to modify at all, then spend the money for an ESL chip and map and a safe circa 300 bhp.

 

Got it fitted,very smooth compared to old ECU,very happy,will get it on Dyno and fueling checked

 

as above, it will likely run OK but best bet for the future would be an ESL board fitted and mapped. If you still have your old ECU the ESL can be fitted to that meaning less downtime.

 

Would prefer to get polar chip but just can't find any for sale

 

you would rather have a generic chip than a tailored map?
doesnt make a lot of sense to be honest.

 

It's the price,polar chip gets great reviews at a fraction of the cost,if I wanted maximum power I'd get it mapped at an expense of £650/£700 which I'd rather put into getting the car sprayed

 

Chips n curry lol

 

Lol read your mappers thread,can bet I no were your car was done originally when I had issues

 

By a pack of flaming idiots mate
Your prob better off going your own way and doing your own thing with your car

 

I will be,if I wanted to pay the cash for a custom map id probably take it to a place in belfast Gsport as he is very good at the mapping but from what I've researched the polar chip will do exactly what I want at a fraction of the cost,just finished reading threw ur thread,that company just up road from me

 

Stay away from the bluffers bud

 

What turbo you running? I miss my wrx

 

Standard, so TD05 16g, I think? I love my WRX

 

Yea tdo5
