Fingers crossed that Cat does the job!

What sort of scan tool do you have? I need to scan the ECU in my turbo project to see what codes are there so I can figure out how to sort out the CEL that’s always on when the engine is running. The ECU is a SF series 2 GT.

Its worked to a point Bennie, but for some reason its still picking up knock from somewhere. Running like an absolute pig at the moment and guzzling fuel. I've used half a tank to 200km travelled on 95, and the foot has to be well into it to go anywhere at the moment. All noise and no go...
Tidied up a few things in the shed and cleared some codes last night, but until I take it for a drive today, I'm not going to know if it's fixed anything. I know the codes for the two front oxy sensors are back again already, just by starting it last night, but I think I'm gonna pull all the heat shielding off the exhaust, it MIGHT be vibrating enough for the knock sensors to pick that up. The new cat is a bit smaller than the OEM one, so maybe the shielding is vibrating there. Trying lots of different things.

I've got a couple of different cables for talking to these things, but at the moment the only one that sorta works is the ELM327 one, which is really basic. Some light monitoring, and code reading, but nothing glorious. My tactrix doesn't seem to want to play on the 30D ecu. Definition files might not be there, but not sure on that.
Gen3 is a pain on this front. Picky SOB it is.
Tactrix should work well for you Bennie, I dont have too many issues on the sedan ecu, as its an 04 STi unit. Definition files are there for the turbo motors.

Anyways. Hopefully get some time in the shed to do some more tinkering today.

Cheers,
Ben

Cant remember exactly what engine you have Bennie but if its got the GD style 2 piece intake manifold with top feed injectors itll be a piece of piss to read that ECU

Got a VAG-COM KKL cable coming that suits freessm on the laptop. Once that arrives, I can interrogate the daylights out of the ECU and TCU, and figure out exactly whats making this SOB run like crap. Be it one of the oxy sensors, the replacement cat not having enough cells in it, or the TCU telling the ECU to torque limit, or if its just good old fashioned knock.

Auto is gonna be gone semi-soon, as I have some classic diff whine from something under the car. Not loud or obnoxious yet, but it's progressing.
5spd is in the process of being removed from the track car per the other thread, and will be shoehorned into this as soon as I have a spare bit of time.

Anyways. Nothing else really of note except the still running like crap. Got 320km to the full tank of 95, so economy is ratshit at the minute.

Anyways, catch ya's all later on.

Cheers,
Ben

Plans have changed... In a couple of weeks I'll have be driving around in a gen5 Legacy...

Been hiding out here, quietly reading peoples updates while my plans solidified a bit. Nothing much has really happened to this thing at all, bar the economy has gone to absolute shite, worse than the above post. 220km to a full tank of 98. I can't deal with this sort of thing as a daily, its just getting way to expensive to get to and from work. The problem could be one of so many things its not funny, right through to even a potential faulty ECU. The VAG COM cable revealed nothing of interest. Could probably interrogate the live data feed, but I'm getting over trying to make it work. No codes, either stored or pending that make sense.

So I'm cutting my losses and parting this out again. Some parts are destined for the track car, others will be sold to help recoup the costs of this amazing little endeavour...

Anyways, I'll be back in a few weeks with a new thread...

Cheers,
Ben

Awww… the H6 dream is ditched. Sad day!

The gen5 sounds interesting. I’m guessing it won’t be stock for long!

Yeah, it sucks, and it was amazing when it ran correctly. Would not even be considering this if it still ran properly, but the time and money required to see this project out is not worth it in my eyes. Realistically probably needs a replacement exhaust plus sensors, engine and ECU to get it running right, and even then that may not even cure it. An extra probably 1500 to 2k I can't justify throwing at it for a MIGHT fix it sorta arrangement.

Haha, you'd be very correct there Bennie! Parts are already sitting in melbourne for it. Not big changes, just therapeutic ones at this stage. Once I actually take ownership I'll make a thread up. Only real downside to it is CVT, but considering its a daily, I'm not too fussed.
