VTune??

3kw from just mufflers? Sheesh that's not too bad. I guess the stockers must have been pretty restrictive then.

Darren,

The bang for buck is low though, $1350.00 for the mufflers (3Kw) and $350.00 for the V-Tune and Injector Power Flush (12Kw).

The V-Tune is the best mod bang for buck in my opinion and the car is a better drive for it!

Kind Regards,

Mark.

Anyone with a 6mt had a Vin tune that can post before and after dyno sheets ? I'm trying to establish a base line for my car before I start tuning.

Cheers,

David.

Hey David,

I can't answer your question, but I'd suggest that when you have the tune done, the first run should be the base run.

David,

I have heard (and seen) some dyno results on other forums of 128Kw ATW pre tune and 140Kw ATW post tune for the 6MT. Do not know about the economy impact. For my 5AT, I had an improved torque of 10% across the entire range from 2500 to 6000 and an improved economy from 9.6 down to 9.2 for my regular weekly drive 50/50 city/hwy.

I had a combined V-Tune and Injector Powerflush for 350.00.

I have the before and after charts in .pdf but I don't know how these can be uploaded on this forum. Alternatively, I could email them to you if you want to PM me with your email details.

Kind Regards,

Mark.

Are you doing a DIY home tune? Because pretty much all places should do a base run before touching anything on your car. Because each car will vary not to mention the different dynos produce different results.

Pulse Racing installed a Haltech piggyback ECU to my '05 Outback (83000km).
Cost $1550.
The result;

Good foundation mod on which to further develop the car i reasoned.

Hi Outback,

Is yours a MT ot AT transmission?

Kind Regards,

Mark.

Sorry Mark, I should have specified that. Its a 3.0 auto trans. Kinda wishing i got the manual now.. The delayed response of the trans is really annoying.

[BlackFlatSix05]

Thanks for the reply's.

Not exactly a "Home tune" as I've been using Romraider on my Wrx so I have some experience and I've had some help from a few well respected tuners. I do intend to have a dyno run when I've finished tuning so establishing what these things have at the wheels in standard form would be good to know to measure the end result. I don't intend to pay for a dyno run pre tune.

I've been corresponding with a tuner here and another, 555 Motorsport in the USA.

I have done a 3rd gear pull and logged my Liberty with Romraider logger and sent the log to both these tuners asking their opinions as to how things are running and where we can make gains in tuning when the definition for my ecu becomes available which should be next month I've been told.

The log shows that my car is running very rich up top and should be able to take a fair bit more timing. Then there's the DBW maps which should improve drive- ability but not KW.

If anyone is interested to see what a Romraider log of my car looks like I'm more than happy to email it to you so just PM me you email address as the log is in Excel and I'm not familiar with how to post it up here unless its just the same as when you post a photo.

Hi mate, great result. Good to know how these things respond to a good tune with a piggy.

I had a Haltech Interceptor on my WRX which was fitted and tuned by Southern Motor Works here in Wollongong.

When Opensource/Romraider became available I removed the Haltech and began flash tuning my factory ecu which was much better than the Haltech. You might be able to flash your Outback ecu next month if your ecu ID is the same as my Spec B. I sold my Haltech for $550.

Sorry Mark, I should have specified that. Its a 3.0 auto trans. Kinda wishing i got the manual now.. The delayed response of the trans is really annoying.

You should be able to fix this delay by altering the DBW (Drive by Wire) maps with a flash or Romraider tune.

That's the problem with Piggybacks. You can only do fuel, timing and boost (turbo).

Romraider or flash tuning allows you to access all areas of your factory ecu.

Talk to Paul at Pulse about this. He might be able to pull your rom and fix up the DBW maps and flash it while leaving the Haltech and tune in place.

Cheers for that tip BlackFlatSix05.
I did talk to Paul at the time of the Haltech install about the trans issues, but his response was that he had no available 'performance enhancing software' for the H6 a/t transmission at this time, as turbo 4's was where all the development focus is. He's an extremely busy man, and i was very conscious of that at the time, and happy to just see what influence the Haltech had on the package as a whole. The engine is noticeably better in every regard. This perhaps, has only highlighted the a/t's faults.
Excuse my lack of knowlage, but what is, and how does an Opensource/Romraider compare to a Haltech Interceptor ECU? In what way was your car much better with the Romraider as opposed to the Haltech? Would i expect to gain even more power with the Rom? Approx how many $$$ ?!
Do you make ur own tuning adjustments via laptop etc?
I havnt a clue whether my ECU i.d's the same as ur spec B. Should i ask Subaru Aus?
Sorry about the twenty questions, but it's the only way to learn up on these things!
Thanx so much for ur advice.

Probably best if you log on to www.romraider.com and have a read but in short the software which is free allows you to access your cars ecu and make changes to many of the parameters such as timing, avcs (variable valve timing) fuel, DBW (Drive by wire) and saving these changes just like you would save anything on a thumb drive or memory stick. Its all done with a tactrix cable which you can buy and plug into a laptop and away you go once you've downloaded Romraider and ecuflash. Romraider is used to edit and log your car/ecu and you need ecuflash (free also) to download and flash your ecu. Our ecu's are not supported at the moment but I have requested a definition for mine which could be the same as yours. Your ecu ID number is on a sticker on the outside of your ecu which is under the carpet on the passengers side front floor foot well. A list of supported ecu's is available on the Romraider website. At present there is only one or two for ADM Liberty's. In answer to your question regarding why flash tuning was better than the Haltech all I can say is the flash tune made my wrx much smoother but there is a lot more involved in a turbo charged car as far as getting the tune right and I think a piggyback just complicates things and is somewhat in conflict with the factory ecu. Probably not as critical in a normally aspirated car as boost control is not an issue so the Haltech is a good alternative especially when flash tuning is or was not available at the time which is why I had one on my old wrx but I think flash tuning is the way to go these days.

Thanks heaps for clearing that up for me mate. I've got a hell of a lot to learn about ecu's etc, so i really appreciate your taking the time to help.
Cheers.
