This is my car, just posting my thoughts here. Its been a big learning experience for me and for the car, but luckily i usually pick things up pretty quick . I contacted edward after reading all the good feedback from people that had their cars tuned. I've noticed immediate improvements in throttle response with light applications, and especially with the v1 rom, it feels like it pulls stronger from low rpm. I'm happy with the gains so far, and edward has been very helpful getting me set up!

Tuning is finish

5kw gain at 500rpm
10kw gain at 6000rpm
10-20Nm gain across the rev range

good bang for your buck
compare that with forking out for an Air intake guide or CAI that give 0.1KW gain

I've been very happy with all aspects of the service Edward has provided. Considering the time difference he's always been very quick to respond to any questions or updates I've sent. The car now feels much more responsive, more powerful, and more linear especially at the top end. The last 1000rpm is actually useful now! The DBW changes have made it easier for me to drive, as i'm used to a more sensitive throttle. The service came recommended to me, and I would recommend it to others as well.

Edward,
Given the number of vehicles that you've now tuned, is there any real trends starting to show
with regards to similar corrections that need making across all teh different cars?

I.e, whether you have enough data to know that every vehicle will need at least 'X' timing pulled or added through a particular load range.
just thinking that this would allow you to build a generic V1 flash as opposed to needing to study all the data from V0 before making any changes.

I guess that if you can build a map like that it will cut down on your time, and give an "instant result" to the customers.

just some thoughts i had

[west_minist]

Sir,

Every car is custom tune. Each car is different and each location adds that extra variable.

I can tune in 1 go. Yes. But I don't think my customers would be happy and XRT represent the X in tuning. I cannot think why a person would settle for less. If a customer wanting a generic, yes.

[Robbks]

i didn;t mean that you would sell it as a "generic" map,
but more to give you a more advanced platform to begin the rest of the custom tuning from.
maybe to save you from needing to custom tune 1 or 2 different versions, when you could use a generic V1 to speed up the process.

[west_minist]

Yes there is some generic one. But each car behaves differently.

[west_minist]

Let me explain. V0 is a finding one. If you been tuned with me, you would know how this rom feels.

V0 all ready have all the changes, except ign. As the versions continues, ign is always tweak, so as some fuel and avcs in minor areas. But mostly ign reduction. Tuning is specific and detail to each customer because each car behaves differently and not only that, a tune once working well with ign, can change dramatically due to fuel or other factors, but mostly fuel.

I hope this help, but the key idea is that each car behaves differently and yes there is a starting point. That's v0 for me. V1 release is more a cleaner rom having all ign compensations.

I would like to start by saying thankyou for doing such a good job and for your patience.
I just flashed V3 DBW and realised how bad the stock DBW is. I dont know how i ever drove the car lol.
V3 is leaps and bounds ahead of stock.
I will flash V3 back on the car.
I did a log but i was in traffic, good indicator of how rubbish stock DBW is, i attached in case you want to look at it.

MY07 Subaru Liberty 3.0R Spec B Wagon Manual with SI DRIVE.
Modifications so far include K&N air filter, TEIN S Tech springs, DBA 4000 wiper slot rotors, Dixcel type M pads, lower control arms bushes.

When i first contacted Edward (aka west_minist) he was very keen to tune my car as was I. I didn't quite have the money to pay for the tune in full but this posed no problem. Pay me some now and the rest later, wow who else would give you those options unless friends or family.

I paid $500 via western union with a $50 fee and we got started. I paid another $250 with a $30 fee two weeks later.
So all up the cost to me was $830 for the tune $230 for the tactrix openport II from tactrix. New Denso iridium plugs IKH20 $70 on ebay US delivered.
and roughly $70 worth of fuel for logs only(not including normal driving around).

$1200 was the end result but once you take the leap off faith you will be rewarded at the end.
It is a worthwhile investment as i get a better feeling when driving the car than the day i purchased it.


Started on a friday night did some logs using romraider with my openport II plugged into my laptop, drove on roads i would usually drive.
Logged normal driving style and some general cruising at set speeds 60 80 110 with the parameters edward requested. I then took some logs driving it like i stole it. Did a couple of back to back 3rd gear pulls hold 2000rpm hit log then wide open throttle to redline letting the rpm drop back to about 2500rpm, stop log. Then same road same direction same point. Remember you will hit around 130kmh in a gear pull so do it somewhere safe.
Gear pulls where only needed for stock V0 and for me V4 Totalling 6 gear pulls.

Saturday morning i had my first tune V0 emailed to me which i saved to ecuflash. Connecting the green connectors at the passenger side i flashed V0 using ecuflash then unplugged them. I read up on the forums and watched youtube to understand the process and contacted edward on msn for piece of mind
First drive the car was very different. It was very responsive and had alot of bottom end torque but felt a little flat up top and nothing much like stock. This is just a base setting for the tuning process, but rest assured as you get each Version the car gets better and better.
More logs emailed to edward and V1 was received on....

Sunday morning. The time difference is great while i sleep edward works on the tune. V1 put my mind to rest the car was now sooo smooth. I couldn't believe it the top end power was back and the new torque levels where still there. DBW still felt a bit too aggressive for my likes so we would change it for V2. Again more logs emailed to Ed and another tune emailed back being V2

Monday V2 flashed on car surprised 3 tunes in 3 days that's quick. V2 was great DBW was working well with good feeling, car again was smoother and power felt nice more logs and a few days later V3 arrived.

V3 This is where the car felt really refined in all driving conditions and i didn't think it could possibly improve but.....

V4 This is where its at the car has come to life. Torque is very strong and the top end pull is ridiculous with no flat spots. If you are game enough to test 0-200+ on stock and V4 you will know.
The torque is so good now you can short shift or go into redline easily. I find myself putting it in 5th gear cruising 60kmh instead of 4th.

Its been about 2 weeks since the start of the process and i am about to do some logs on V4 for V5 but i am assuming that's where it will end.

Forget looking at the dyno pulls they don't do the tune justice, driving the car along your usual route is where you will notice the difference in the tune. They are just there for reference.
The car pulls from alot earlier and the power is linear not like the rough power band we are all used to.


The rev limiter has been raised slightly to a safe level. It doesn't have that annoying cut out that we have all hit from time to time going into the red.

The DBW is where i am the most impressed. I was blessed/Cursed with SI DRIVE and for those that have it know what i mean.

Stock
Sport# is quite nice when driving hard but too aggressive for peak hour traffic.
Sport mode has so much throttle lag it is almost impossible to drive. I would almost stall the car on take off every time.

V4
Now Sport is very easy to drive throttle is responsive and power is usable in all conditions traffic or open roads.
Sport # has gone to the next level the throttle response is just as crisp but you get more feeling from the pedal.

To keep all my logs consistent i used same fuel from same servo (premium 98 octane) fuel level was always around 3/4 full and i was always on my own to keep weight consistent.
I would usually log between 9.30 and 10.30pm only because of traffic.

Unless you have modified your intake or exhaust you must remember you are tuning a stock car so there wont be massive power gains just better fuelling, drivability and improved torque from earlier in the rev range. But if you have modifications edward can still give you a custom tune.


Overall edward is very helpful and professional. I have no problem recommending his services to the next 3.0R Spec B owner.
These are just my thoughts and opinion.

Hey Ladies and Gents,

If you are looking at a based map to little or no tuning, I can offer this service now. Do not expect peak performance as it is not custom tuning, but a map you can get and drop on that will change many parameters as in custom tuning, which I perform.

I am able to do this based on my local customer feedback on his JDM Legacy 3R, which I carried out the same function.

Because XRT custom tunes so much, its hard to accept not having a really tuned car, but we answer to custom's needs.

Costing will be half the price of custom tuning as stated here:- viewtopic.php?f=53&t=7575

Please email or pm me if you are interested or have any questions.

West

Do you get many requests for fuel economy tuning for the H6 for the NA engine?

Are you able to make any improvement on the factory fuel economy?


I think the new service you offer and the pricing was a VERY good idea, it will filll the needs of most people

[west_minist]

I think every customer gets better fuel economy once they adjust to the car. I actually reduce fuel as Subaru's runs very rich at you approach high rpm. You will see 9's. AFR. So yes they do, but I encourage them to keep to the oil and spark plug changes. Change spark plugs on every second oil change. Oil changes should be done well under 10000km per oil change. The MAF should at least be clean on second oil change or unless you live in a high polutant area.

Also keep your tank above 1/2 full. Subaru's have pickup issues.

I hope above helps.

Yes I think this new service can help, but I am trying to decide what is change to what is acceptable for me to release full accessible maps. The JDM customer does check and does not allow anyone to touch his car and he asked me about tuning if anyone ask. So its trust related issue. So far I haven't receive any request.

A few people have done local tuning and I have asked them for logs for just dyno, rpm and speed and I never get them. So I guess their tuners maybe frighten to compare their tunes to mine. All I asked for is rpm and speed logs for dyno'es. but it would help people to compare on a basic level the effects of tuning.

[Tradewind]

Also keep your tank above 1/2 full. Subaru's have pickup issues.

INTERESTING- Same problem for all NA 2.5 liter Subaru Impreza since 2001 also

Our supercharger kit install instructions mention keeping tank above half full for all later model 2.0 and 2.5 liter Impreza

Now I know to expect same from Liberty

It does seem the problem doesnt exist with WRX or STI, is that correct??

[west_minist]

Yes it does exist for all models. Not sure about 2008+.

Now you know why Subaru's feels better on a full tank lol

Some of my customers appreciate...well my driving style in testing... Some don't But the harder you drive the more that pickup shows.

Wellll I drive rally style within limits not to hit It just added that touch to tuning when the customer needs it. I more specialise in the STI. I hate off boost performance, so I use WRX techniques in tuning to enhance the STI bottom end. I hope to get a 2007 JDM STI next year if I can, once the house bug does not bite me, but a house would be a wonderful project
