Due to the environmental changes, it is very hard to say that power has increase substantially or to a noticeable amount. What has change in respect to the owners feedback is that the car has become responsive and the DBW performance has improved.

AVCS tuning, unless more is perform where we run less for testing, has showed no improvement and the maximum map set of 50 seems to be the max it will go. I would pretty say the car is max out as it is. I am not sure of the other markets, including JDM, but modifying it and working the Ignition map for the gas it runs now, makes the car very consistent.

Here are my thoughts on the ADM 2004-2005 Liberty:

• DBW needs tuning to improve throttle response and control
  Fuel requirements for the car is a little higher than usual and in some cars, maybe a little to high, cause great inconsistencies in power delivery and operation
  The fuel map looks good, but could be a little richer in some areas and leaner in others
  Modding the car and reworking the Ignition maps for consistencies on gas is a major aim for consistent power and operations
  The AVCS map seems optimised, but at this point in time, data is inconclusive.

I look forward to your thoughts.

I personal think that tuning the DBW and working the ignition map for Aussie gas, is the key in tuning along with mods such as a full exhaust, exhaust headers and intake systems.

If anyone is interested in just DBW changes tuning, along with the reduction of pinging causing varying performance levels, please pm me.

The tuning process is almost complete. We began with Edward’s test or finding rom V0 and we are up to V9 however some of the versions were numbered V1a, V1b, V1c etc so many hours of data collection and too many logs of cruise and pulls in all gears from 1st to 6th have been done as well as many kilometers and tanks of BP Ultimate.

Some unseasonably cold weather and now hot weather have made the results somewhat difficult to determine but I have to say that the results are superb.

We started with a car that was constantly trying to find a happy medium by pulling timing due to knock/pinging and an IAM which was all over the place not to mention what can only be described as an uninspiring dead or lazy throttle response.

What Edward has done is made the car come alive the way it should have been when it left the factory. He has tuned the car to suit our fuel and our atmospheric conditions which has transformed the car into something much more acceptable to someone who enjoys driving a drivers car.

The changes to the DBW maps gives the car much quicker and crisper response to light throttle application and the power delivery is more linear just like a cable operated throttle. You actually get in acceleration what input you give the pedal and you don’t need much of it to make it all happen with no delay.

I did ask Edward to make the DBW more aggressive which he did and I like it. Even from his first touch of the rom it was better. He made it like that from the beginning to make it constant for tuning purposes and he told me he would make it more aggressive for me once the tuning was finished which he did.

I still need to provide Edward some logs of rom V9 which I hope to do in the next few days but I’m really happy with how the car is performing so what ever tweaks need to be done now will only be very minor.

If you own a H6 then get yourself a Tactix cable and PM Edward. I’m sure he will help you with a competitively priced tune and you will benefit from the work I have done with him. I was in communication with another well known internet tuner who I was going to use however he had not tuned a H6 either so had no data or base roms to start with. Edward has all the data from my car so it should all happen quickly and smoothly.

Own a H6 ? Do it now.

David, thank you for the review here and on xtremeracingtuning.com

It was interesting to see the 3.0R in operation and I can only dream how it feels and the sound out the exhaust.

Guys, if you are interested in getting the DBW tuned, along with tuning for your fuel, please PM me.

Because of the time it takes and the effort, I think charging H6 owners a modest fee of $150-160USD for the whole tune seems very reasonable. Turbo owners gets charge $600usd for stage 1. Because of the power increase and very little room for tremendous power, H6 tuning should not be expensive.

Going through logs takes a very long time, especially if it is a driving log like what you see above. I literally drive through the log to get a feeling for the car and driver style. Like for example, David seems to like to drive in torque, because his power is 6000+, but he shift at 5500+. lol

The time for tuning takes as long as you can get back the logs to me. So if you are interested, please PM me or email me at socob.bb@gmail.com for details. I can also be reach at west_minist@xtremeracingtuning.com

I look forward to your queries.

Tuning is now complete for my car.

All I can say is I am more than happy with the service Edward has provided. The final rom was V13. To arrive at this there were many versions. I have 29 saved however, there may have been more that I didn't bother to save.

Many hours of flashing and way too many logs of the various versions/revisions of the roms have been completed to arrive at what we have now.

What was learned along the way is these cars are no where near their full potential from the factory and suffer from fuel pick up problems below half a tank and also spark plugs could do with a change at 50,000km not 100,000 as recommended by Subaru.

I now have zero knock/pinging in my logs and the IAM is constant now at 1 so there is no timing being constantly pulled by the ecu and the car is running at it's absolute best for our fuel and atmospheric conditions.

Compared to how it was before Edward's efforts it is ballistic for a stock 05 3.0RB. It's not like my old WRX but a hell of a lot better than before.

For my last rom Edward tweaked the DBW a little more which has made the car more lively and fun to drive. Edward could tell from the logs that I heal and toe. The DBW changes have made this easier as the throttle responds to slight applications.

I must also thank Tommyspecb for lending me his laptop and Tactrix cable. Without that all this R & D would not have been possible. I will be assisting Tommy with his tune when he is good and ready.

Edward is a top bloke and I hope that this R & D helps him in his business.

For those of you who don't know Edward is about to become a Dad for the first time. Good luck with that Edward. I know you hardly sleep now.

I know I've said this before but honestly if you own a 3.0 H6 Liberty/Legacy and want to get the best out of it then get in contact with Edward and get it tuned. As the mule/guinea pig all the hard work has been done so your tune should be over and done with in no time at all.

Cheers,
David.
