Subaru Impreza chip upgrade ECU performance mod on eBay, also Chips, Performance Tuning Parts, Car Tuning Styling, Cars, Parts Vehicles (end time 15-Mar-08 12:53:03 GMT)

Can someone enlighten me as to whether these are a good idea? It all sounds good, and is reasonably priced, but its almost too good, unless it is that easy to get extra power!
I have a full decat exhaust and a blitz airfilter.

THanks Mike

run away.

Run away fast... There is no chip that will cover all imprezas, simple example, the wagon and saloon have different turbos, the wrx, sti and RA have different rev limits.. so no.

If you want to go down the chip route use a reputable supplier who will supply a chip for your make and model.. I have a polar performance chip from scott T on here and its been great.

Unless you know the map on the chip ,as jd5217 said, don't bother.


no idea what a 'stage 2 tuned impreza' is

Speak to Scott T at PolarPerformance for the chip he can supply and he can offer you customer support.

There are some people who don't like the idea of using chips to increase the power etc and prefer a remappable solution (APexi power fc,Simtek,ESL daughterboard etc)

pretty much what i thought, ta

IS removing the resonator box in the air intake a bad idea??

satancom

No i think thats quite a common and safe mod.. will increase induction noise and standard dump valve noise though!

mikey2

iTrader: (1)

ok cool, not too worried about the noise, its never going to be quiet. Thanks

Tidgy

generic maps are askign to play catch the piston!!

stay well clear.

dont worry, i am not gonna bother, i have a unichip which i plan to have fitted and mapped for the car anyway, gotta be better than nothing!

Tidgy

tbhj its not the chip thats the problem, its the map on it, it needs tailoring to your car.

so if your having a chip fitted and then mapped to your car you should be fine.

no idea on how good unichips are

mikey2

iTrader: (1)

i know they are quite old, so are no doubt going to be bettered by others, but if it does its job then its ok. Its got a spura map on it at the min so its not going anywhere near the car until its fitted properly and mapped straight away. Mind you, the car runs like a bag of sh*t at the min so prob wont make much difference, lol. *joke*!!!!

would an sti intercooler be easy to fit to the wrx? i think they are the same age, or same design anyway.

What year is your impreza?

Isn't the Dastek Unichip a piggyback ecu?

mikey2

iTrader: (1)

yeah it is, my car is a 93 L wrx.

mikey2

iTrader: (1)

Its got a Z4 ecu in there now, but at the minute its not running well at all, its only on 2 cylinders so until i get it right i wont be doing anything anyway. Its been off the road since Nov, but i am getting another ignitor for it, and am hoping that will solve the drama.

satancom

It will fit.. but lotsa modifications are needed... Done it myself, hard work.. Trim the Throttle body and intercooler, trim the rear engine mount shroud, weld up the DV hole and relcate (leave blanked if not using a dv)... remove the old intercooler brackers, move the wiring harness against the firewall down a bit, and the vacume hose above out of the way!

Its more hassle than its worth on an early car...

Tidgy

if its a 93 then just get the standard ecu mapped

mikey2

iTrader: (1)

its not got the standard ecu in there, i think that went ***** up so i changed it for the z4, i still have it but i dont trust it, have had loadsa probs with the car, coil packs exploding, running on 2 cylinders. The ecu chucked 16 codes up originally, then i reset, went down to 12, then i changed THE ECU and had 1, the idle air solenoid, now i have changed that aswell so should be down to none.
Can the Z4 be mapped?? if so who by?

jd5217

so you have fitted a different ecu to the car and wonder why you are having problems

dan83590

Early ECU's cannot be mapped. Speak to any of the mappers on here and they'll be able to supply a good chip that can be plugged into the ECU and matched to your car. An example here.

Not very helpful!! Why not try and explain instead of just shooting him down?

Tidgy

thats not true anymore, only 96 ecu's are a problem

dan83590

Why, whats changed?

Tidgy

the standard chips can be mapped

dan83590

I didn't think the standard ECU came with a chip. Do you mean the ESL Live board?

mikey2

iTrader: (1)

no not really. I apologise if i wasnt clear, but... i was having problems before i changed the ecu, all the problems infact, not only that but its been better since i changed the ecu, no more error codes.
I was driving along one sunny day and i lost all power, well most of it, car wasnt responsive and was very juddery, i pulled over and discovered the coil pack had melted, so i took it home and parked up, it has been there since, i changed the coil pack, the second one blew up, literally. i am in the process of changing everything in the ignition line, the ecu, the ignitor and the coil/sparks.
So far i havent solved it, but i am waiting for a new ignitor. I was under the impression that the z4 was a suitable ecu upgrade for the wrx.

Tidgy

chips all over it lol

jokign aside, i should have said the standard ecu can be mapped.

excpet that on the 96 impreza
