As my exhaust is on its way out due two a hole in tailpipe and the cat starting to blow, Iv'e been advised to replace the exhaust, I'm thinking of a Blitz Nur Spec straight through to the down pipe.
So I will need to replace the ecu which ones would u recommend. I'm not wanting to highly mod my Scooby but if the exhaust is blowing my engine could be running lean.

You don't have to replace the ecu just for exhaust swop. But if you really want to then I would go for thr TSL live mapping board priced at approx 500 quid mapped, the Simtek will set you back approx 1200 quid.

£1200!!!!!!!!

from enginetuner £995 fitted mapped inc VAT

Sorry should of said that included antilag at 150 quid. Total price was 1160 I think, so approx 1200 quid

jd5217

thats better

renno rannes

I think its £150 + VAT for the anti-lag upgrade.

just remap the existing ecu, don't need to replace the whole thing, or scoobyecu it

what year is the car and if only changing the centre and backbox you don't HAVE to get it mapped.

Depends what year the car is. I would not bother with a remap just for an exhaust.

KINGTIGER

Sorry guys I've should of put cars details its a 97 STIV5.
Well I asked if I could get away with replacing the ecu and they said without a new ecu your car would run incorrectly and could damage engine.

Sooo someone told you to replace your ecu because of a blowing exhaust (am i correct?) and you will replace it with a stainless steel exhaust.

Methinks someone is taking the ****

sorry why do you want to replace the ecu? (should of read the post better sorry)

KINGTIGER

Well at the mo Iv'e a Apexi Exhaust Stainless steal all way through to first cat. And my cat is blowing aswell so they said to decat but will need to replace ecu.

Imports only have 1 cat in the downpipe don't they?

I run my earlier import with a decat and it's fine (a few r/r sessions) to get the best out of a decat a remap would be better.

possible it might overboost with decat downpipe.. 97 is unlikely to be version 5 btw..

Simon

KINGTIGER

Ok I will be thinking on doing that. Anyway evan though I'm using t99 I might need a remap for fuel anyway. I will probably check out Scoobybits as its not to far away from me.

2 cats, centre and down pipe. If it has a stainless system then just replace the cat that is blowing with a decat pipe and forget about new ecu's you won't need one.

KINGTIGER

I'm still debating weather its a V4 or V5. I've posted pics up and people hav come back saying its a v5 something to do with the interior and Clear headlights. The dealer said its a V5 is there a way by looking a vin

chassis code for the version 5 sti is GC8F4ED,code for the version 4 is GC8E4ED IIRC.Things get slightly more complicated if its a typeR but try Which Car is a WRX STi

This is my old v4.
The front end + interior only came like this as a V4.

You can tell by looking at the engine:

V5/6 the dump valve is bolted to the front of the intercooler and the coilpack is on the right side of the inlet manifold on V4 the coilpack is in the centre of the inlet manifold.

KINGTIGER

Well this is a pic of my Engine. And I believe from the pic the DV is in front of intercooler which could mean its a V5.



If it is a V5 it must be a MY98

Jolly Green Monster

that is indeed a version 5 and it is therefore possible to remap the orignial ecu using EcuTek.

Simon

KINGTIGER

Great I will be considering it. So if its a version 5 is it a my98

2.5STI

what about on a 98 uk... would that need a remap if it just had a full system...?

MartynJ

Don't forget chaps that the SimTek is also available for the 99-00 cars and does away with the dreaded crappy MAF.....!

KINGTIGER

Well I've just decivered the applied code and I'm rather happy its not a my97 infact its a MY99 so does that mean its still a V5 or is it a V6. I'm rather happy bunny, as the dealer said the price of the car goes by condition mileage and age and he said its a 97 so was sold at 6500 now they had a 98 model in which had about 84000 miles on which he was selling for 8500.

So is there anything extra I need to know is the MAF dodgy on these models

MY99 = V5
MY00 = V6
