Have you got a wideband?

yessir. 

[gotasuby]

I could do my best to walk you through it/ look at logs etc. Is wideband inputted into ecu

I don't suppose you'd be able to help me remotely just to get a safe run in tune on my RA??

 

Could get dwight to do it 600 for a road tune if it goes swimmingly.

It's not yet. I'm getting all my final parts this week and will be putting the RA together. So probably in two weeks time.

I'm booking in for D-Tech on Jan 23rd, but need to get motor run in by then.

Can run in on dyno. Most do. Not worth toasting an engine to save a few bucks before hitting the dyno. Its not hard to get fuel dialled pretty quick but without proper knock gear I wouldnt be too keen. Remember you need to load the engine on run in not nana it.

[gotasuby]

I do agree with evo wrx. It could be done but risky. We only run race engines in for 20-50km now and then fully tune them. This is on endurance, rally engines etc. With today's fine tolerances and machining along with the materials used that's all they need. If not run in by 20km they won't ever be run in.

Good news to CHCH based members. SAS has just bought a Dynapack hub dyno. it will take a couple of weeks to get setup but after that i'm hoping to help guys out that want to tune their car. I was going to suggest putting their car on the dyno and teaching/show how to tune and what affects what. There will be more information over the coming days/weeks.

 

And to ibpenguin, it could be knock but would definitely get it looked at. Dtech and PBMS i have heard good things about and not too far of a drive

 

This sounds good, can't wait to see my car on your dyno!

Is that the stm one @gotasuby

Yes it is

Sooo from my limited knowledge on wg duty this looks ok but i thought to get better and more ball and spring mbc sudden spool feel i would run closer to 100 on the wg duty at low rpm... thoughts?

You dont need 100% dc to keep the gate shut.

ahh ok, i did not realize that. So its probably as good as it can be. i trust DTech have done a good job. just interested in gaining some knowledge on the topic

 

this is an interesting read; http://www.clubwrx.net/forums/tuning-electronic-engine-management/134360156-wtf-tuning-part-2-turbocharger-101-basic-boost-control.html

Remember that's max wastegate duty not what it will run unless poorly setup

hey thoughts on carberry rom on stock ECU for v7 STI? any features/setup to ask for when taking in for dyno tune?

 

also is it worth it for me to have link ecu installed while at the tuner or other things i could better spend the cash on? carberry does speed density already which i heard can be an advantage when set up right (which link also does) but i believe carberry doesnt have closed loop boost, not sure what else there is..

Okay, so before people (Adam @kwi_fozze) jump in and say that replacing a factory ECU in v7+ is useless. Here's some important things.

 

Links have a much more in-depth fueling, boost, and timing tables.

Can do Closed loop

Significantly easier to tune (really can't deny that, it's 100% true)

Veeery easy to configure to setup change

 

Carberry has it's advantages, yes, no doubt.

Like not having to fork out a S*** load of cash for an ECU. ¯\_(ツ)_/¯

 

However, in the case of where a car is, lets be honest @Batbaruman rather modified like your own, a Link will possibly come out ahead. 

But once again, it might not actually be needed.

Is the initial outlay for a link 2.2k+1.2k tune vs stock ecu 0k+1.2k tune cheaper hell yea. Is it easier F*** no. Lack of tuners let alone someone who uses carberry...links easy to play with even at muppet level. 

[Kiwi_Fozze]

Yeah... I have to admit links are a shkt tonne easier to tune.

 

But the v7 ecu is free, and does about 95% of what a link does, without a 3.5k total outlay.

 

Fairly sure the latest carberry has closed loop boost, will need to check. But I use stand alone boost control because I cant be arsed with the boost maps (lol?)

 

Each have their disadvantages and advantages.

 

A good tuner will be able to set up carberry as its still speed density, but can run maf as well (also closed loop fueling)

 

It comes down to money. Can you squeeze 500hp from the stock ecu? Yes. Is it user friendly? Not really. Bit its a retunable ecu that you dont have to pay for.

 

There was someone pop up recently who was pretty scathing of the link he juat bought, same tuner as his carberry tune, got an extra 2 or 3 kW at the wheels, nothing else changed. Ended up with a 3.5k outlay for a more user friendly ecu but no increase in power (worth writing home about)

 

Talk to your tuner tho. Best place to start, have a yack with the poor sod who's setting you up

[KingCole]

Dont you need an IAT sensor with the Carberry that you need to hook up? I have heard great things about it but you would need a good tuner to tune the car with Carberry.

[Andy_Mac]

Get a link. I'm starting to sort on the wiring for mine now with the stock ecu staying for controlling non engine related stuff.

Stock ECU's are good when they work correctly, but you're relying on someone on the other side of the world to spend their unpaid free time getting it spot on which doesn't always happen. Mines a good example of this where the boost control wasn't addressed/indexed correctly so there has been no control of it and alot of wasted time and money chasing the cause of it.

 

Sure issues like that won't be present on a much more common ECU/vehicle like a V7 STi but food for thought

[Batbaruman]

cheers guys, should have mentioned car is already running on carberry rom and was tuned on it by Gary Capper. Since last tune previous owner has changed turbo hence my need to retune and considering ECU upgrade while i'm at it. PBMS were offering a deal for CS members on the link when we tune with them so I'm super tempted on the Link just waiting to hear back about final $$$ impact

[kgsyeti]

The new Link ecu's are good if you are constantly changing the car whereas for a once off mod session a reflah is good. You can eliminate the afm with the Link too.

 

[Abomb]

Anybody around Hamilton run open source? I need a little tuning done, I'll buy the cable if need be. 

[willisnz]

Random question, if you lived in central/west Auckland (Avondale) where would you go to (legally) do 2nd gear pulls for an e-tune?
