[V8 / 9 Catless Downpipe]

Thanks for that info, I'll check. It's a 2005 vehicle but off hand I don't know when it was first registered here but I suspect it was around 2010. Cheers.

[V8 / 9 Catless Downpipe]

Hi All,

Just thought I'd ask the question, has anyone out there got a good catless downpipe to suit a V8/9 sti that they are looking to sell? I'm guessing I'll end up buying new but thought I would ask first!

Cheers,

Colin.

Ok, I'm ready for the onslaught of laughter and or abuse - just wondering if anyone out there knows much about these things - the pro's (if any?) and cons of using one and any problems associated with them. You read such conflicting opinions online.

Don't shoot me - I'm just curious if they offer any realistic benefits as a launch control or anti lag type system?

Cheers.

[What have you done to your car today?]

Fitted alternator cover and air intake that I just hydro printed carbon fibre AND fitted the new black projector headlights. I have to confess, they are a bit 'ricer' but I can't help it, I like them, they give it a slightly meaner look! I'll add some pics later so you can judge for yourself.

[ECU Help!]

See my 'from the beginning' thread. Mystery solved by a mechanic waaaay more knowledgeable than me! He tracked down a dodgy bit of wiring under the dash that just suddenly decided to cause problems.

[From the beginning!]

The great news is that now we can get on with the rest of the work required to get this car back to its best! Thanks to all for the helpful info.

[From the beginning!]

Unbelievable! It turned out to be a stray wire / wires under the dash causing the problem. They were left over from previous owner and poorly fitted previous alarm / immobiliser and just suddenly decided to cause problems. It's just ironic coincidence that the timing of this happening coincided with the other work around the car going on. All credit to the mechanic for tracking it down. Bingo! Now either of the ECU's runs the car, starts first time on both of them! Cars! Gotta lovem!

[From the beginning!]

Thanks for that. The mechanic is due back out in the morning, he has told me that the battery not charging and the fuel pump not running are both likely features of the failed board. We don't know why the replacement 1s board won't run it either, but I guess we'll know more tomorrow? It will be interesting if it turns out that the board not being bolted in correctly had caused the whole issue though! Cheers

[From the beginning!]

Thanks, we'll try that next. Could this problem come from the ECU?

[From the beginning!]

Now it's quiet, I got my son to check (car's at his place) and no, there's no sound from the fuel pump!

What's the cause I wonder?

[From the beginning!]

I'll check both those things again tomorrow - unfortunately working with noisy rain this afternoon so unable to hear anything going on.

Thanks.

[From the beginning!]

Ok, I wonder what the wealth of knowledge on here might be able to suggest. I'll relay the story from the beginning and see what you reckon.

My son's V4 StI has had a full bottom end rebuild and the heads done but it wasn't running quite right. Stuttering on take off almost like a misfire or fuel cut but was running ok once it got going - and then was boost cutting under heavier acceleration.

Diagnosis was bad plugs and a leaking boost actuator - both changed on Friday last and running much better as a result but not perfect. The ECU was also suspect as it had got wet 6 months ago and we wondered if it was causing minor running problems as a result (although it has been functioning ok since being dried out).

Anyway, the same Friday evening - it refuses to start, not even turning over - I tell my son to check the ECU connections because I know the mechanic only plugged it in (leaving it only finger tight on the bolts, planning to return to it next week)he pushes the plugs home again, bolts it down and hey presto the car starts.

He drives it home fine but once home and stopped, it won't restart - you can just hear the starter solenoid clicking but that's it.

I stupidly suspect the same ECU problem and when we remove it you could smell that electrical 'burnt' smell. Take the top off and there is a visible small component that looks like it has been too hot and the insulating material is cracking off it. This must be the problem?

So, I get hold of Johno's 1s ECU, plug that in - the same, just clicking.

Now the penny drops - maybe just not enough juice in the battery! Jump leads and sure enough it turns over but won't start. Try a remap? Turns over but won't start?

Back to the original 75 ECU? Turns over, won't start? Remap? Turns over, won't start?

Now in that awkward place - pretty sure the battery is not what it should be but would like to get it running first to isolate whether it is the battery or alternator that's causing the low charge. Now have 2 ECU's, the original which definitely has something at fault but we don't know if it is causing the non-running plus the 1s ECU and we don't know if for some reason it simply won't run the car?

Right now I'm stumped so any suggestions or tips would be welcomed! Cheers, Colin.

[ECU Help!]

What a good bugger! I went to see Johno today to collect that ECU - and he even gave me a couple of interior parts for my boy's V4 STI as well!

Well, if he ever needs a favour, he knows where to come. It's so nice to deal with someone that's just genuinely friendly and helpful!

The only unfortunate thing is that the car still won't start on either ECU so not at all sure what the issue is now? Oh well, time will tell.

[ECU Help!]

Thanks for that - trying to get something local that I can go pick up straight away if I can.

[ECU Help!]

I spoke to a Suby fanatic mechanic - he reckons as long as it runs the yellow injectors and the orange AFM it'll work just fine, so I'm keen! Colin.

[ECU Help!]

I'd be keen to come and collect it - right now if it suits?

I've PM'd you.

Thanks.

[ECU Help!]

We've just had the ECU die in a 1998 V4 GC8 STI. Is there anyone out there got one to sell? We're in Tauranga and keen to get this thing running again. If you know the best place to get one (close to home) any advice would be welcome. Cheers.

[Best place for spares?]

We need to find a lot of small odds and end spares for a 98 GC8 STI. Any recommendations on where to go to find them as local to Tauranga as possible? Cheers, Colin.
